    Due to the errors in the spelling and grammar, it is hard to distinguish what you are saying...... Can you clarify please?

Hi

If the light on the ECU is not flashing any codes then it is the ECU at fault, either due to an internal fault, or due to a supply voltage or earth fault.

If the light on the ECU is flashing then you need to count the flashes and pauses to formulate a fault code which will then point you in the right direction, but I would say that because you say the car would run okay whilst the PGM FI light was on then it could be the primary O2 sensor at fault.

However, I would look at the light on the ECU before condemning anything.

Regards

Geordie

My 1994 5-speed manual Pathfinder sputters and jerks when it's cold


Here are the common cause of surges, stalls at stops, slow idle speed, erratic idle, it is in most cases the idle speed control air-bypass valve and/or throttle valve and upper intake, these area's get full of gunk and combustion residue over the miles and cause idle issues (stalls, low idle) like yours, Get a can of intake cleaner from any local parts store, not carb spray, intake cleaner, it is made by a company called CRC, remove the air intake hose to the engine, hold the idle high so the engine won't stall, then spray the can of cleaner into the intake while keeping the engine running, use at least 1/2 the can, shut down the engine and disconnect the battery for 5 minutes, then restart and complete a number of mixed driving

Will not run at an idle


Try this, it is the common reason for this problem.
Here is the common cause of surges, stalls at stops, slow idle speed, erratic idle speed, rough idle and engine hesitation (and other problems), it is in most cases the idle speed control air-bypass valve and or throttle valve and upper intake, these area's get full of gunk and combustion residue over the miles and cause idle issues (stalls, low idle) like yours, Get a can of intake cleaner from any local parts store, not carb spray, intake cleaner, it is made by a company called CRC, remove the air intake hose to the engine, hold the idle high so the engine won't stall, then spray the can of cleaner into the intake while keeping the engine running, use at least 1/2 the can, shut down the engine and disconnect the battery for 5 minutes, then restart and complete a number of mixed driving cycles, town, freeway, stop and go etc., after a few days the problem will go away as the system will relearn to the clean intake

Car is stalling and idleing irradically.


I Would Suggest That You Complete A Engine Cylinder Leak Down Test.....(not A Compression Test But A Leak Down Test) this will tell you if you have internal problems....possible worn rings or a burnt valve(s) I would use a smoke machine to check for vacuum leaks also. Good Luck

93 s10 2.8 wants to stall out after restart


You probably have a clogged fuel filter. There should be an inline fuel filter between the gas tank and motor, replace that and your good to go. I have the same problem with my c10 pick up.

Have to jump every day if not driven and revs funny


what sounds like is a failing battery plus the reving is cause by the sensor in the air flow meter, for that buy a can of air flow cleaner and clean the air flow meter and all the intake system.
