96 grand am SE power pack
Does this look like it would cause issues with the car running correctly? The car just started acting up one day and I had to tow it home. I could get it to start but it would backfire and miss terrible. The minute I put it in drive it would stall. Now it doesn't want to start at all. Sounds awhful when its cranking.
I had the ICM tested and it shows it is fine. I had two codes that I pulled and one was p0300 and p0172. I had read that some people had issues with the vacume line that went to the pcm, i think that is correct. Any suggestions would be appreciated. |

Re: 96 grand am SE power pack
A vac line to the PCM? That's a good one.
That's the ignition tower, you have a picture of.... Have seen carbon tracking problems in that white tower, cause misfire problems......but also you could have a coil problem(there are two in the tower)....could even have an ICM problem.....I know you had it checked, but more often than not, ICM's don't fail when cool and tested.... If I had to guess, I wouldn't be leaning towards the ICM.....Have replaced a lot of towers, and have replaced some coils...... With that P0172, I would also pull the vac line to the F/P regulator to check for fuel in the vac line.... |

Re: 96 grand am SE power pack
Glad you got a laugh from that one. It's the MAP sensor.
I'm going to check those first before I spend anything on the ICM or coils. Thanks |
