My car started to misfire about a week ago only when the car has been sitting around for an hour after being driven or it will take a long time to start or both. When it misfires you can smell raw gas in the exhaust and will only misfire for about 4 min at the most. I have changed the cam postion sensor and the fuel injection relay yeaterday. I have done a complete tune up except the coil. Tell me if you guys have had similar problems and what you did to fix them. Please need feedback

 

Any codes in the ECM?

 

No codes at all doesn't even pop a check engine light still checked though

 

Sounds like one of the injectors are leaking when the car is off.

 

How could one of the injectors be leaking when the car is off? I don't really get that I am thinking that the coil is going bad.

 

The injectors are like a valve that opens and closes. Sometimes they go bad and bleed down. You can remove the fuel rail and watch and see if they leak.

 

I would pull the plugs and inspect. When was the last time the wires were replaced? Cap and rotor?

 

I had a car once that had a weak return spring in one of the injectors and it did the same thing.I would do as Tech suggested, pull the fuel rail and see if one of the injectors is leaking down.
