88 pontiac 6000 shudders and stalls after approx. 30 min. driving

what in the world is a 88 sunbird, ISUZU"?
or a
1988 Pontiac Sunbird Sedan???? wrong forum
same as all cars.. this your first?
read car repairs for dummies first. (read the safety issues, 2 times slowly)
generic on all cars. (ive posted this like 10 times) searches work.

• remove battery neg lug
• gain access to starter, (jack stands or what ever it takes)
• remove the wires/cables from starter solenoid.
• remove the 2 mounting bolts. at starter
• it falls out.
• reverse above with new.

alldata.com has every bitsy steps.
and no engine stated.

I would step on accelerator and the car would hesitate and half the time stall and shut off engine. I had the PCM flashed to more current software (tis s3114b8) and the car stopped hesitating and stalling. Cost 135 bucks at dealer although some shops can do it cheaper.

Sounds like the engine is starving for fuel - plugged fuel filter, failing fuel pump, malfunctioning fuel regulator, etc. Have the fuel pressure checked.

Sounds as if the catalytic converter is clogging up. Air restriction threw the engine.

RICH MEANS TOO MUCH FUEL.........OF NOT ENOUGH AIR? ANY OTHER CODES?

Check throttle position sensor (TPS) is a sensor used to monitor the position of the throttle. The sensor is usually a potentiometer, and therefore provides a variable resistance dependent upon the position of the valve. The sensor signal is used by the engine control unit (ECU) as an input to its control system. The ignition timing and fuel injection timing (and potentially other parameters) are altered depending upon the position of the throttle, and also depending on the rate of change of that position. For example, in fuel injected engines, in order to avoid stalling, extra fuel may be injected if the throttle is opened rapidly (mimicking the accelerator pump of carburetor systems). the cost about 50-75 bucks.

try replace cooling sensor

You need to replace the TCC solenoid under the side cover pan of the transmission. You can also unplug the wires that go to the transmission in the front. After that it will not go into overdrive but it will stay running at stop lights untill you have it repaired.

there is a couple of things you can do ,, reset you computer take the hot wire off your battery for 5 min. then if that dont work check transmission fuild,, dirty trans fuild cause transmission not to down shift and stall

Hi,have you done a fuel pressure check on the vehicle.This will check the status of your fuel pump.If its a carb engine it will be 5 to 7 psi.If its fuel injection it will be approx.35 to 45 psi.Good Luck!!!
