hi there, you see todays cars are so emmision friendly that not even the vapors from your tank can be released into the atmosphere so what they have done is all your vapors are put into a charcoal canister to absorb the vapors and the next time you start the car it has a purge solenoid open and burn the vapors off. if you look around the intake youll see a hose with a green cap follow it back to the charcoal canister and while your doing that just check the hoses and the hoses around the canister to make sure there is no holes or cracks in them and then follow the hose from the canister to the gas tank. if every thing looks good then i would replace the purge solenoid.

- hi there again, sorry about not getting back with you sooner but my computer jammed up on me i finnaly got it going now on the evap system dont worry its not complicated at all first check from the fuel tank to charcoal canister, its just a solid plasic line that goes from the top of the fuel tank(which you wont be able to see without dropping the tank) just check for cracks or unplugged tees or elbows at the canister. 10 to 1 Im betting that the purge solenoid is bad its usually located by the canister or it on the intake with a two wire connector. now another little place you might check is on the intake. you will see another plastic line coming off the intake going to the purge solenoid it will have a green cap (test port for evap system) see if the line just came off the intake . now you can by a pressure gauge and test it there but im pretty sure youll spot the problem before it gets that far

I have owned my 1996 Cavalier for just over a month and I notice that it seems to rev alot when you start moving forward and takes along time to find second gear. The car also jerks sometimes when you put your foot on the pedal to move from a stop position ie: waiting at the lights. Can anyone give me any ideas to what this might mean? Is it the transmission?
