I have a problem with the car missing on the trailing 1 coil. I have replaced the coils and the plugs are new, i just replaced the motor and it ran fine for about a week. i do know that the bolt to the crank angle sensor fell out and the timing was screwed up after that the coil started firing funny, only on the trailing 1 coil though. i have an 88 gxl. please help!!!

 

i now have fire on all coils but the maf is still acting funny. instead of a constant flow of air it takes in gulps at a time and idles funny. it also jumps time once in a while?

 

why do you say its the AFM? Is the idle very uneven and stumbles, etc.? If so, you prob have a vac leak. That or tps needs adjusting.

 

yea it stumbles, i dont think its a vac leak i just replaced all of the vac lines with silicone lines

 

****. That silicone line idea sounds like a good idea. I'm probably going to do that. Have you checked the car when it is at it's operating temperature? I'm sure you know that the bouncing idle is usually a TPS adjustment thing. It'll probably go away after the car has warmed up some.

 

the tps is maxed out and it still wants to die?

 

no its runs when its cold its when it warms up is when it gives me problems and the intake sounds funny

 

Anybody else out there think it might be the CAS? That would be my guess.

 

well i had 2 of them and i tried swaping them and it did not help
