My 318 TBI engine likes to always keep me guessing. Some days it will fire right up and run like a champ, others not so much. This is a list of what it does: Cranks normal amount and runs fine, Cranks long and idles like it has a monster cam in it, Cranks many rotations and revs to the moon once it fires, Cranks normal and dies as soon as it fires up, then other times it will crank and crank and sputter and try to fire and finally will after like 20 seconds of cranking. It idles with that lopey cam sound a lot more on winter cold starts but all the symptoms I listed kinda just happen whenever and no matter the temperature. I have a new Idle Air Control Valve that I haven't installed yet. Anyone else ever have the same problem?

 

Oh, also, both fuel injectors drip a lot of fuel at idle. They spray better under acceleration but still drip some. I just haven't replaced the injectors because I'm having trouble finding ones that are correct.

 

Cam sensor and air sensor would be my guess. Leaning more towards air sensor.

 

Sounds to me like it has a PCM issue???
