1997 chevy cavalier 2.4 twin cam engine dogs out when throttling

I have a 1997 chevy cavalier 2.4 twin cam that i have put every sensor, valve, timing chain,... on this thing just short of replacing the engine. i have taken it to the chevy dealer and numerous auto repair shops and all don't know what is wrong with my car. Problem: you can start the car and it will idle. when you step on the gas pedal real slow it will rev up pretty much normally. if you throttle it down the engine falls on its face (coughs, sputters, backfires) and will die if you don't back off and bring it up slow. as long as you bring it up slow (on the highway)you can go as fast as you want. any ideals?

    did you ever find a solution to your problem? it sounds like mine, only my car doesn't die. you hit the gas and it chokes out but if you are soft on the throttle you can go as fast as you want. please let me know if you figured it out.

Possibly bad tpos sensor

Bad idle air control valve

Bad maf sensor

Check the computer codes first before spending any more money on it

Also do a compression check

And check your valve timing and ignition timing just in case.

We took the head off an found that the valves are hitting the pistons on my 1997 chevy cavalier 2.2


Only way that can happen is if the timing belt/chain has failed and the cam and crank are no longer in phase with each other.

Replacing head gasket on my 94 cavalier I have removed the alternator, intake and exhaust are loose; question is how do I keep from throwing the timing off when I pull the head?


there is not a way to not affect the valve timing, the cam belt must be replaced in a repair like this, when u put it back together you must reset and confirm all the valve timing marks are in correct alignment, just no way way around this, if the cam is timed right the engines ignition timing is correct as well and will require no adjustment. this answer applies to all engine that use a cam drive belt.

I have a 97 2.4l twin cam in 2001 will it work


It will work as long as you have the ECM to match the Motors. The regular 2.2 has a different engine management system then the 2.4 so the engine will fit but the ECM needs to understand the engine.
Good luck and hope this helps.

My 1997 chevy cavalier wont start.its getting spark and fuel.but wont fire it has a 2.2 ecotec.


Sounds like cam belt has snapped. If it broke while starting, could be cheap fix...new belt. Worst case: cylinder head off for overhaul...bent valves / pistons replaced.

I have a 1997 chevy cavalier and my throttle position sensor is shorted how do I change it.


No big trick here, just unbolt it and put the new one in. If it's adjustable use the dirt on the throttle body as a guide for proper placement. Make sure it engages properly on the throttle shaft as well.
