Well, until last night the gtp was running fine without a problem Then I get in and take off about a minute later the check engine light comes on.
I know the guy I got the car from said he had that come on just previously to me getting the car and smoked it and didnt find any leaks but around the gas cap area but it wasnt the gas cap so he ran some sealant around the opening. Didnt have any more problems.
So now that came on and I was running down to the last 1/2 gallon of gas as I pulled in the gas station started sputtering. Put some gas in and no more sputtering. Hop on the highway and hit 70mph and was runnin at 3k rpms. Wouldnt get into overdrive.
Tonight I went to the gas station again and was getting down to the last 1/2 gallon again and started sputtering goin into the gas station again. I shut off the car and get out it smelled like rotten eggs outside the car. Then I got back in and the whole car inside was full of the smell.
So I went to autozone and got a p0440 code (evaporative emission system small leak/no flow condition).
(1)Defective or loose fuel cap
(2)EVAP canister or or hose cracked not connected
(3)Purge or vent solenoid defective
(4)Vacuum leak at engine
Well I got the gas cap just to try it out, its definitely not that. The guy I got the car from said pretty much everything was replaced. Said to try the fuel tank pressure sensor. But I was looking around and it seems like that would be a different code.
Any help here would be appreciated I dont wanna play the troubleshooting game of replacing a lot unnecessary parts..
