94 Cavalier Help

[bobbyr1229]

I have a 94 cavalier that while driving today made a loud enough pop for me to hear on route 4 then it bogged down and is now idling very rough almost like the engine is loping and it struggles to get past 30 mph I push the gas to the floor at 30 mph and it doesnt want to go anywhere any suggestions?

Catalytic Converter?

That was my thought, the converter in my 86 Cavalier died (yes this was a long time ago) and top speed suddenly became 30mph. I don't remember any loud pop, though.

Slap a spoiler on it.

Sounds like it jumped Timing. May need a new timing chain and tensioner. I have '97 S10 that did that same thing.

dont know if you still have issues with the car...

to check if it jumped timing by a tooth you could try advancing or retarding the timing by rotating the distributer... that is if you have a distributer... beware though if it is an interference engine (which it probably is) you could make it worse if the timing is really off...

head gasket could have blown... check for leaking coolant or if the exhaust smoke is different color than usual after car is warmed up. also check for any oil leaks.

Can you hear a clicking sound, or a metal on metal sound??

You may be getting ready to throw a rod through your engine block.

oh yeah if it revs fine in neutral (even though idle is off) could be tranny
