The famous and unsolved code P0351
 

I everyone, I sure do need your help for this one. It's about the code P0351, I put the coil #1 on #4 change all six spakplugs, went to the garage and have the injectors clean up, and the f?%$# code still on, do I have to change the injector? is there anyting I can do before I go to the dealer? And can you tell me where the ECM is, I'm thinking of changing it.
Thank's guys.

Did you clear the code? Unhook the battery for 10 minutes and that will reset it. Then fire it up and see if the code comes back.

Same problem, comes and goes
 

I have the same problem for a few months now. I did the same things you tried. It will run fine most of the time, but usually once a day, it throws the code. It will run bad for a few minutes, then clear itself up. I have no clue what to do next. I have a code reader, and I reset it every time it throws the code.

Finally I went to the dealer, it's only a cutoff wire from the ecm, it cost me 45$

Please explain
 

Please explain, was it just a cut wire? or is there something called a cutoff wire? Where is this wire, any information you have would be greatly appreciated. If I can do this, I would be more than happy to take pictures and post step by step instructions.

It's a loose wire that connect in the ecm

Thanks, I will hunt down this wire and do a write up on the repair.
