It has to be a bad fuel sensor

SOURCE: Rough idle until warm

HMM, ya ont get a code unless ya figure out how to read the morse code values the OB1's use. Hmm sputters, and rough idle can be from poor air circulation, as well fuel delivery.

first air.......inspect and clean your vacuum hoses, cracks and leaks will most notably ruin your day. as well as the performance of your ride. check the seal for your intake hose around the throttle body, then clean the ports in and around your throttle body as well. Bad air supply, poor idle.. follow me..


second is fuel delivery. Your getting your gas, thats evident, but are you getting the required amount. hard to guage unless you disconnect a line and test its pressure. so lets USE the KISS method.. KEEPING IT SIMPLE STUPID

first, check and or replace your fuel pressure regulator...

second, inspect condition of your fuel filter.

thrid, and certianly the last thing, your fuel pump. go in that order. or your gonna seriously annoy yourself when a 5 dollar fix turns into a 3-400 dollar fix.

SOURCE: jeep starts and runs for awhile then shuts off

Hey Mike, it sounds like a problem with the ECM or a wire going to it, if the wires sheath does not look damaged I'd say that it's probably dry joints in the ECU. If you were to take the ECU to an electronic service shop it will likely be a lot cheaper than getting a new unit. I'm not sure what you mean by the federal emmissions ecm i'm in Australia, we don't have those.

SOURCE: I HAVE 95 JEEP GRAND

Had similar problem with 96 Jeep 4.0L engine. Tracked it down to the connector for the distributor pickup. Spliced in another connector and hasn't stalled since. Also, have you had any codes? Easy way to check on Chrysler products: turn key on, off, on, off, on (not starting) and watch the 'engine light' on the dash. It will flash off/on. Count the flashes with short pauses between and longer pauses between code. When you get a 5 count and 5 count, that is the end. This may also help

Ok...you mentioned that there is no spark coming from the coil when it's in no start...Is there power from the alternator going to the coil?
One other item...If the timing chain is worn and stretched, it is possible that the cam sensor and crank sensor are out of phase with each other, just enough where a temperature difference will change starting ability.
One question...while in no start, have you tried changing the throttle position while cranking to see if it lights at part or 3/4 throttle?

SOURCE: 1996 jeep cherokee shuts off with no warning signs

Suspect fuel pressure. You could install a fuel pressure guage. There is always a fuel pump cutoff safety switch. It is either in oil pressure switch or alternator connection. But have you changed the fuel filter?

My 96 prelude keeps shutting off when hot. What do I do to fix it?


96's are kinda the bad year for our cars being the only obd2 4th gen preludes so for any codes over 43 you have to look it up in the '97-'01 manual. Code 65 is "Secondary Heated Oxygen Sensor Heater Circuit Malfunction (Sensor 2)". Probable causes are an open in the secondary O2 sensor heater circuit or bad ECU. Have you tried resetting the ECU to see if it comes back? If so, you could check for loose wires coming from the secondary O2 sensor in the cat converter going to the 4 pin connector, or if you have access to another ECU I would try to substitute a known good ECU to see if that clears it up. The troubleshooting flowchart is on page 11-79 in the '97-'01 helms manual, and involves checking resistances and for continuity.

I think this could be the code I had on my '96 when I bought it. I tried replacing the secondary O2 sensor, and long story short it was the ECU. Luckily my '96 was still under the extended emmissions warranty, so Honda replaced it for free. I don't think you would be covered under the extended warranty because it was 14 years and under 150k miles. I just barely made it (within a month or 2 and 3k miles) last year.

As far as the engine sounds and rough idle, you could just need a valve adjustment. The secondary O2 sensor just checks the cat to make sure it's working right.

And all auto trans want to move forward when the brake is released.

2006 Ford F-250 6.0 Engine just shuts down at an idel or going down the road. it has a bad glow plug and shows a code for it . I just replaced the cam posithion sensor. Does the engine keep shuttting


I have had the same problem with my Ford mustang the only thing is that it only shuts down in high idle, after the engine temperature warms up there is no shut down. It could have something to do with the transmission or the temperature sensor the best thing to do is get a full diagnostic and not do it your self.

My jeep has issues with shutting off at random times. It can happen when I am driving or idling. If I am going fast, I will lose my acceleration and I will have to pull over. The engine will either pick up...


The issue lies with any of the following three things 1) can sensor 2) crank sensor and 3) ignition coil. Check the quality of the spark at the plugs as a way to check on the coil output. Next some Jeeps have one coil per two plugs and some have coil on plug. If you have one coil per two plugs disconnect the two plug leads to one of the coils (on four cylinder engine they are arranged plugs 1 + 4 on one coil and plugs 2 + 3 on the other coil). Turn the engine over and sparks should jump between the terminals on the coil. If this happens the crank sensor continuity is OK and that it is detecting crank position, if not then this a strong indication that something is wrong with it. Check it for cracks and check the wiring all the way back to the ECU and check the connection is clean. Replace it if suspect. Now physically check the cam sensor. Any cracks or distortion in the body of the device replace it. Check connections and wiring back to the ECU. Generally the cam sensor goes wrong when the engine is hot. If you get random shut down even when starting up this indicates that it is more likely to be the crank sensor or coil.

Autozone and similar stores will check the codes in the computer for free usually. That is the best place to start. Other possibilities are Engine Coolant Temperature sensor (saying the engine is cold when it's not) or excessive fuel pressure (bad regulator or blocked return line)

OK, you have a code PO341 which means their is a problem with the signal the ECU is receiving from the cam sensor. It does not necessarily mean the sensor is bad. It can be one of these things.
1. Cam sensor wiring routed too close to spark plug wiring (causing interference) 2. Poor wiring connection at cam sensor 3. Poor wiring connection at PCM 4. Bad cam sensor 5. Damaged reluctor wheel You replaced the cam sensor and the problem is still there so we can assume that a defective cam sensor was not the problem. Do this.
1. Check that the wiring isn't routed too close to any secondary ignition components (coil, spark plug wires, etc.) 2. Visually inspect the wiring at the sensor for any burn marks, discoloration indicative of melting or chafing 3. Visually inspect the reluctor wheel through the cam sensor port (if possible) for any missing teeth or any damage 4. If reluctor isn't visible from outside the engine, visual test can only be done by removing cam shaft or intake manifold (depending on engine design)

2004 F150 5.4L engine misfire


The concern is likely caused by the coil which sits on top of the spark plug. Your P0301 indicated misfire on cylinder 1. Your P0316 indicated it occurs on the first 1000 revolutions. Your P0171 indicated lean on bank one. Bank one includes cylinders 1,2,3 and 4. Your lean code is strange but could be related to misfire. I would recommend swap the coil on number one with number two. Clear the code and drive it. I would expect to see a P0302 which indicates the misfire traveled with bad coil. good luck.

95 maxima rough idle


The injector could definitely trigger a misfire code, but you also mentioned that you had a mass airflow sensor code , that code code be responsible for te sluggish moment of the vehicle and rpm going up and down. However if you have a misfire onCyl#6 and the coil and the plug is good the ONLY other thing to cause a mis-fire would be the injector. To check the injector get a NOID light, you can get one at almost any auto-parts place. To use unplug injector plug from the bad injector and connect it to NOID light the light should have a steady PULSE/ligt flickering. If light flickers fine then injector is bad and will need to be replaced. If light doesn't flicker or flickers intermittently then you may have a bad wiring to that injector. Check if wiring is good, then you may have a bad cam sensor or sensor gear. Good Luck and contact if you need more help. Thanks for using FIX YA
