Hi mdjd894...

Sounds like you have dirt/debris in your carburetor jets or fuel passages.

Make sure you are getting spark at the spark plug, to do this:
Remove your spark plug and check to be sure you are getting fire at the spark plug.
You do this by grounding the plug on the head of the engine and pulling the crank rope, if you are getting spark then:
Check/Clean/Replace your fuel filter if you have one, normally they are located in the fuel tank of weedeaters.
Also make sure you are using fresh fuel...and oil mix if your using a two cycle mower or weedeater with the oil to the right mixture and not too much oil as it can cause hard starting.
If the mower/weedeater is over a year old, then I recommend that you buy and install a new carburetor repair kit,because the diaphragm will get hard and that will cause it to be hard to crank.
Sounds like you will need to clean the carburetor or replace your carburetor internal rubber parts like the diaphgram and O rings.
I recommend that you use a laquer thinner type cleaner to clean and dissolve the laquer build-up in the float and needle jet passages.
Be sure to remove all plastic and rubber parts before using the laquer thinner because it can dissolve the plastic parts and render them unuseable.
Be sure to use compressed air to blow out all the fuel and air passages.
Be careful when blowing out the passages, because there are sometimes small rubber type seats in the bottom of some of the passages.
Sometimes you can get by with priming the carburetor or using starting fluid and letting it run a few times like that and it will flush the gunk out of the jets,but most of the time you will need to rebuild the carburetor.
Keep in mind that the float for the carburetor must be level when you go to reassemble the carburetor or follow the instructions you get with the carburetor kit.
When you clean your carburetor and remove the jet screws, you will first need to lightly seat the jet screws.
But before you lightly seat the jet screws count the number of turns it takes to seat the jet screws from their original position.
Be sure to mark the turns down on a piece of paper.
That way when you put the jets back in, you know to lightly seat them first and then turn them back out to their orginal position before you started.
Once you have your carburetor rebuilt that should solve your problem.

98 Chevrolet prizm stalls when put into drive. Replaced crank sensor ignition starter alternator and it is still stalling


Most likely the idle air valve or throttle motor is broken or stuck or not receiving signals from the engine ECU to increase the air flow to the intake in response to an increased engine load and therefore maintain the idle speed at the preset value.

I have a 2005 Dodge Grand Caravan SXT, Got a OBDCII reading of P017.1 and P017.2 simultaneously and I am confused to the reading. Can you help clarify?


P0171 is a lean code an could be caused by several different things besides a vacuum leak , Bad O2 sensor , mass air flow sensor , stuck PCV valve etc... http://www.obd-codes.com/p0171
P0172 is a rich code , here again could be several thing's - mass air flow sensor , injectors , O2 sensor , fuel pressure regulator etc... http://www.obd-codes.com/p0172

I have a 2002 honda accord lx 2.3 automatic My car starts and stays running until I give it gas then it stalls. I put in new tps sensor, spark plugs and the rotor and the fuel pump and still no change plus...


Check your engine wires or boots if this is a coil over set up. but i dont think it would cause a complete stall, just a crappy idle unless really bad...

Checking sensor activity would be best with a scan tool. Watch your MASS AIR FLOW SENSOR (MAF) G/S should increase as engine speeds increase. It should not be stuck. Tap this part if it appears in a stuck value it sometimes acts up and can show its self. This part watches air going into the engine. If this is false, the engine cannot meet the demands from you because it is has no idea how much fuel to mix or has a bad idea due to sluggish sensor. G/s @ idle is usually around 4g- 8g depending on most cars.

Also check for typical vacuum leaks and intake hose leaks. if you replaced this many items. My best guess would be check MAF sensor.

Good luck

Stalls out when gas is let off


You don't say what size engine you have, so diagnostic analysis is a bit difficult. Please supply engine size and answer these questions.

1. After it stalls, do you sometimes smell fuel?
2. Does it restart easily after a stall, or do you have to hold the gas pedal to the floor to restart it?
3. Can you keep it running by working the gas pedal?
4. Has you fuel consumption increased since this began?

I ask these questions because on most engines there is a coolant temperature sensor that the ECM used to control the amount of fuel to the injectors based upon the engine coolant temperature. When the engine is cold it supplied more fuel than when warm. If the sensor malfunctions it tells the ECM that the coolant is -40F
and that causes massive fuel to be supplied. This may not affect a cold start once the engine needs the fuel, but it will flood and stall out the motor when warm. If you can keep the engine running by pressing the gas pedal, you are allowing the motor to rev up and use the extra fuel, but you will find you gas mileage reduces by as much as half.

My truck starts and stalls and will not idle


Try increasing the idle speed. If you don't know, this is how to do it.
Open the bonnet and ask someone to push and release the gas pedal a five second intervals.
Observe which part is moving.
Yo will see a small adjustment screw on that lever. You will understand that by adjusting the screw you can increase the gas supply to the engine.
Slowly rotate the screw while the engine is running. (If the engine doesn't run in idle state as you have explained, ask someone to keep the pedal slightly pressed. After increasing the gas supply, ask the person to release the pedal).
Adjust it further to get a smooth running condition at idling.
Also check whether air cleaner is blocked.

98 vw beetle will idel won`t take gas speed hand does not work.


If you are saying that your bug idles but stalls when you push the throttle, then look to replace your MAP sensor. This MAP sensor increases gas flow as you push the throttle down which increases the air flow. Also get an OBD2 reader and get your error codes from the ECM system. Not as hard as it sounds. When you get the codes you can look them up or ask at the auto parts store.

1995 mercury villager check engine code p1200 injector open


P0400 = EGR Flow
P0325 = knock sensor (Do not ever change a knock sensor, they don't affect anything and cost $600 to replace for absolutely no gain)
P1200 = I can't find this one. I think it's injector flow
report back on what you find.
Egr flow may be plugged egr passages or a bad solenoid.

1996 PCED OBDII-Villager SECTION 1B: Description and Operation
Exhaust Gas Recirculation System
Exhaust Gas Recirculation (EGR) System Operation The exhaust gas recirculation (EGR) system (Figure 1 below) recirculates a portion of the exhaust gases into the intake manifold under average vehicle driving conditions to reduce combustion temperatures and exhaust gas NOx content. The amount of exhaust gas recirculated varies according to operating conditions and will be cut completely under:
  • Engine starting condition
  • Low engine coolant temperature condition
  • Excessively high engine coolant temperature condition
  • Engine idling condition
  • High engine speed condition
  • Mass air flow sensor failure
The exhaust gas recirculation (EGR) system on the Villager uses the exhaust gas recirculation/evaporative emission (EGR/EVAP) control solenoid valve to provide vacuum to both the EGR valve and the EVAP canister when commanded by the PCM. If the exhaust backpressure is sufficient to close the EGR backpressure transducer valve, vacuum is sent to the EGR valve and allows EGR gas to flow into the intake manifold. If the exhaust backpressure is not sufficient, the EGR backpressure transducer will remain open and allow vacuum from the EGR/EVAP control solenoid to vent to the atmosphere.
The EGR system monitor, for OBD II regulations, uses an EGR temperature sensor to monitor the EGR system. The EGR temperature sensor is a thermister located in the EGR passageway. When hot exhaust gas is recirculated into the engine, the temperature at the EGR passageway increases. This increase is sensed by the EGR temperature sensor and a signal is sent to the PCM to indicate EGR flow. If the EGR temperature sensor does not detect EGR flow when commanded by the PCM after two consecutive drive cycles, the malfunction indicator lamp (MIL) will be illuminated and a diagnostic trouble code (DTC) will be stored. The MIL will be turned off after three consecutive drive cycles are completed with no malfunctions detected. The DTC will remain stored in the PCM memory until 80 drive cycles have been completed without the same malfunction detected in the system.

Exhaust Gas Recirculation (EGR) Backpressure Transducer Valve The exhaust gas recirculation (EGR) backpressure transducer valve is used to control EGR. The EGR valve is operated by ported vacuum, but the ported vacuum will normally be vented off at the EGR backpressure transducer valve. As rpm increases, exhaust pressure increases and pushes on the diaphragm in the EGR backpressure transducer valve and closes the vacuum vent.
Figure 2: EGR Backpressure Transducer Value
Item Number Description 1 — Throttle Valve 2 — Vacuum Port 3 9D475 EGR Valve 4 9F452 EGR Backpressure Transducer Valve 5 — EVAP Canister 6 — EGR/EVAP Control Solenoid 7 — Vent
EGR/EVAP Control Solenoid The exhaust gas recirculation/evaporative emission (EGR/EVAP) control solenoid (Figure 3) is controlled by the powertrain control module (PCM). The EGR/EVAP control solenoid controls vacuum to both the exhaust gas recirculation (EGR) valve and to the evaporative (EVAP) emission canister. When the EGR/EVAP control solenoid is off (12 V signal from the PCM) vacuum is supplied to both the EGR valve and to the EVAP canister. When the EGR/EVAP control solenoid is on (ground supplied by PCM) vacuum is vented to the atmosphere keeping the EGR valve closed and no vacuum to the EVAP canister. The PCM will command the EGR/EVAP control solenoid on at:
  • Engine starting condition
  • Low engine coolant temperature condition
  • Excessively high engine coolant temperature condition
  • Engine idling condition
  • High engine speed condition
  • Mass air flow sensor failure
Figure 3: Exhaust Gas Recirculation/Evaporative Emission (EGR/EVAP) Control Solenoid
Exhaust Gas Recirculation (EGR) Temperature Sensor
The exhaust gas recirculation (EGR) temperature sensor (Figure 4) is a thermister type sensor that monitors the temperature of the exhaust in the EGR passageway. As the EGR flow increases, the temperature increases. This process creates a change in the resistance of the sensor, which decreases as the temperature increases. The signal is sent to the powertrain control module (PCM) to indicate that the EGR system is working properly. If the EGR temperature sensor does not change resistance as the PCM expects on two consecutive drives, the malfunction indicator lamp (MIL) will be illuminated and a diagnostic trouble code (DTC) will be stored.
Figure 4: EGR Temperature Sensor Exhaust Gas Recirculation (EGR) Valve
The exhaust gas recirculation (EGR) valve (Figure 5) recirculates portions of the exhaust gas back into the intake manifold to reduce the amount of the NOx released during combustion and to reduce combustion temperature. The amount of exhaust gases that are released into the engine is proportional to the load on the engine.
