mm1500lan -> Cavalier engine problems (12/6/2007 3:55:01 PM)


My son purchase a used 98 Chevy Cavalier with HO 4 cylinder engine. It has 125000 mile and he is having nothing but problems. Great looking car he had it a month when it started to misfire, we replaced the plugs and coil packs spark plug wiring system. It ran great for a month, now we are having problems again. If the car is running under 1500 rpm’s it runs great. Push the accelerator any harder and it dies remove your foot from the accelerator and the engine will still run as long as you are under the 1500 rpm limit. It does the same thing in park. We are not finding any error codes. We have replaced the fuel pump after our GM mechanic told us to. $500.00 later the very same problem.

u could have a throttle position sensor problem. those don't always throw a code.

franktorres -> RE: Cavalier engine problems (1/10/2008 4:09:41 PM)

it could be a number of things it can be throttle sensor, egr valve, or fuel regualtor

all of those sensors always put out codes, wether the engine light stays on, or just comes on once and a while then shuts off.

Fuel pressure regulator?

dirt_cavi_54j -> RE: Cavalier engine problems (1/20/2008 2:52:16 AM)

to me it sounds like a fuel pressure regulator or maybe even the fuel filter needs replaced

shawnvw -> RE: Cavalier engine problems (1/20/2008 9:41:57 AM)

I would also have a look at the fuel filter. a clogged filter can starve the engine of fuel when it needs it the most. Although it should have been replaced when you did the pump
