ok i know this is a camaro forum but my cousin has a 92 cav (at least its a chevy) shes telling me that it starts real rough and doesnt stall but the rpms will drop real low almost to a stall shes in ny and im in sc so i cant look at it to try to see what the thing does soon she will be venturing down to sc (about 900 miles) she tells me that after about 5 miles or so it will get a little better but not the same as a month ago im thinking fuel problem maybe the filter i was alsothinking the pump but when she told me it gets a little better i started to drift away from the pump i told her to try the stp compleat fuel; system cleaner and see if that does anything does any of this sound like anything you could think of (also she has no codes i told her to get it read anyways incase the bulb was blown she was a little upset to have to spend the money with no code) she also replaced the plugs and wires

 

Is the check engine lite lit? Most likely the car could use a tune up (plug, wires,filters, etc..)

 

like i said no cel just did the plugs wires cap and rotor about 15000 mi ago air filter just replaced last oil change am i safe to say its a fuel problem

 

Could try adding a couple of bottles of good injector cleaner, like Techron, to a full tank of gas. May also want to clean out the EGR valve, in case it is not closing fully at idle and WOT.

 

also forgot to mention the engine was replaces roughly 30000 miles ago and i belive there is around 60000 miles on this engine and what is WOT

 

WOT = wide open throttle. And the EGR (exhaust gas recirculation) valve still might go bad, but on a '92, it's not so easy to check - a check-engine light may or may not go off if the valve is bad, I don't know if the '92s had OBD I or not. A quick check of forums (Search for Cavalier OBD I and reading the flashing CEL light codes) might bring more info.

Then again, a '92 Cavalier might not be worth fixing, as they probably won't go for much even at junkyard prices - especially in rust-prone NY.

 

as long as it make it to sc every thing will be good she plans on getting a new car once she gets here but doesnt want to buy a rusty piece of sht from ny
