While driving and holding steady speed, the rpm's fluctuate 200-300 rpm's


How many miles are on this vehicle? Is the engine light on? If so, can you have the codes read? RPM fluctuation can be anything (both caused by mechanical or electrical changes or failure/s). Fuel pressure, engine compression, 02 sensors, worn or sticking TAC unit, vacuum leak, poor fuel quality, dirty or defective MAF sensor, clogged air filter, old spark plugs, excessive exhaust back pressure, stretched timing chain, over due oil change, worn or damaged throttle pedal, or worn out spark plugs. These can all cause your symptoms. Let me know if you have anymore questions.

2002 PONTIAC MONTANA P0420 CODE


This code sets because the onboard computer senses that the exhaust quality before vs. after the catalytic converter do not meet design specs. It determines this via the upstream and downstream O2 sensors in the exhaust.
Possible causes are:
Poor engine performance.
Damaged/defective converter
Damaged/defective O2 Sensor(s)
Exhaust leaks

I recently replaced the engine on my Citroen c4 2005 model, now the warning lights stay on, the engine overheat, abs and anti pollution warning lights stay on.


The problem for engine overheating rise due to insufficient refrigerant. Try recharging the refrigerant tank with fresh refrigerant and water. If the refrigerant in the tank is of poor quality then also engine overheat.

The reason for ABS light to come may be due to air in the brake fluid line. Try brake bleeding to remove the air bubbles. Also the faulty brake actuator line may cause the problem. Check for actuators on each wheel.

Pollution warning light comes on if the exhaust system not works properly. Check for faulty Oxygen sensor or faulty catalytic convertor.

What can I do to fix these codes from recent inspection?


P0300 is a random engine cylinder misfire has been detected by the control computer of the system, it is called the PCM. Common causes are dirty fuel injectors, engine intake manifold vacuum leaks with poor quality fuel as the last item. Other issues cause this problem as well including general condition of the engine like low compression, only careful testing and diagnosis will find the exact cause or causes.
P0420 Catalyst System Efficiency Below Threshold
This indicates that your Catalytic Converter is not cleaning up the exhaust emissions to a preset level, it is mionitored again by the PCM.
Possible causes are engine vacuum leaks (may be related to P0300 problem), exhaust leaks upstram of the Catlytic Converter
All poss causes are listed below.
Possible causes - Three way catalyst converter Bank 1
- Exhaust tube leaking
- Intake gasket vacuum leaks
- Fuel injectors may be faulty
- Fuel injector leaks
- Spark plugs may be faulty
- Improper ignition timing
- Powertrain control module (PCM)

P0507 Automatic engine Idle speed Control System RPM Higher Than Expected idle speed during test.
Possible causes - Dirty throttle body
- Electric throttle control actuator misadjusted or damaged
- Faulty Electric throttle control actuator
- Intake air leak
- Poor electrical connection to the Intake Air Control (IAC) valve

Hello my mustang is sputtering badly, idles at between 900 and 1000 rpm. has a bad exhaust smell and acts like it wants to stall alot. the oem codes it gave were po303 and po316. what does this mean and...


303= cylinder #3 misfire the 316 is just another code for misfire detected during start up:
I would say buy a new plugs and wires, this will correct the problem, Tim

  • Faulty spark plug or wire
  • Faulty coil (pack)
  • Faulty oxygen sensor(s)
  • Faulty fuel injector
  • Burned exhaust valve
  • Faulty catalytic converter(s)
  • Running out of fuel
  • Poor compression
  • Defective computer

I have a 95 jeep wrangler 4.0 it turns over has fuel and spark but wont start


If the fuel is getting to your cylinders and so is the spark, then one of two things are out of whack... either the timing is off, of the fuel/air mixture is wrong. Check your error codes using a code reader, available from almost any automotive parts store. But not all readers are the same. Some just read, while other are capable of resetting the error codes, which must be done once the error has been corrected. This code will direct you to the problem if it is a sensor issue, which governs the fuel/air mixture. If there is no error code then it has to be the timing...it might be a stretched belt, where it has jumped a tooth, IF it is a belt as opposed to a chain or gear drive... this is easily diagnosed with a timing light, hooked up and scoped to the correct specs. One to 5 degrees off of the optimum timing settings, should not prevent your vehicle from starting, but when you are WAY off your timing then you should consider that you will need to replace the timing belt. There is no other way for your timing to be that far out, The timing belt has become so worn that it will no longer keep the timing, even if you just reset the belt and everything else, it will just jump a tooth again,...it will be only a matter of time.
