Question about 1997 Chevrolet Cavalier

1 Answer

1997 z71 5.7 350 stalls after warming up (bout 10min. of driving)

Runs great on a really cold day! runs worse as it gets hotter! when its cold it will burn the tires off then the more gas u give the less power it puts out and if you floore it it`ll fall on its face.temp gage never goes over 195 witch should be normal. i have changed spark plugs,wires,button,cap,air filter,and a 185 deg.thermostat. new catalic conv. and tried running without any on. engin light is not on so no codes to find. problem has going on for over a year .none of my local shops can figure it out. some say tourk converter, transmission cooler, im not a mechanic but i think its some kind of relay swich or sensoir but dont know where to start. thanks for your time!

    I have two of these same trucks out in my driveway and they both do the same thing. They have always done it.

Please Help 97 Chrysler Cirrus Stalling out

Could be alot of things. If it runs good when cold and gets worse when warm, at low RPM, it may be the EGR valve. May just need cleaning. A plugged fuel filter won't cause the light to come on, but it will cause a lean condition, which will. Possibly a bad crank sensor, they have been known to have trouble at the connection, check it to make sure it's clean and tight. it's on the pass side, at the rear, were the motor & trans bolt up. first things to do are to make sure the battery connections are clean and tight. Then replace the filter..Please click on this link its the service manual ,,,

Good luck..

Problems accelerating

the engine tickover is too slow when the engine is cold its running on cold start, ie:choke,, after it warms up the engine slows down this is what is causing it to stall in gear,, get some one to hold the brakes hard on and with the engine running in gear ajust the tick over till its reving at 750 - 850 rpm the revs will go up a bit when its out of gear,, before you pick a gear to go into push the foot brake down to stop the car lurching,,,

Guessing gets expensive. Is the check engine lamp ON? If so, there will be stored trouble codes that are necessary to propely determine the cause of the stall. Catalytic converters do not unplug when cold, if they are plugged, they are plugged at all temps and vehicle runs worse the more gas you give it but may idle OK. Typically, stalls after warm are electrical failures, often computers, or solid state components that fail when they heat, and cool off over tyme. Ignition components are highly suspect generally, as are sensors. crankshaft position sensor especially is common to fail only warm on most vehicles.

When engin warms losses all power if floored it just sputters!

Have u replaced the MAF sensor?, that is what this sounds like, when they fail they cause a severe loss of power but don't turn on the check engine light, a quick way to test it is to disconnect the sensor and idle the engine for a moment then drive it, if it runs better the sensor is the problem. Here is a photo.
