Hey guys,

Car is a 3.8L camaro with 62k miles.

So i drove the car home and SES light came on, the p1351 code came up on my scanner.

Its something to do with an open circuit, ICM wiring voltage for coil 1&4.

Its beyond my comprehension on how to address this since the coil, ICM are fine.

While driving home it didn't accelerate right, very slouchy coming off a red light. RPMs were up to 2900 and car was only going 20mph but it picked up speed gradually.

I really appreciate it if someone can shed more light on this before i have to take it to shop again.

Thanks!

How do you know the coils and ignition control module are fine?

More info on the car would be helpful, year etc.

Probably the ignition control module (under the coil packs).

Other possibilities are wiring between PCM and ICM or PCM itself.

The car is a 2001 camaro 3.8l

I replaced the ICM and all 3 coils just to test if any of these 4 things were the problem.

But the ses light with the code p1351 came back on again.

Message on scanner is saying something about voltage being too high on coil 1&4.

Thanks fellas!
