I received this code 10-24-12. P1352 #2 coil primary
Having dealt with the coil cascade in 2008 (3 went out in less than 1000 miles), I replaced all 5 coils and plugs with the ones recommended for my vehicle from IPDUSA. I reset the code.
It ran well for 2 days then I got the P1352 code again (no check engine light).
I switched the number 1 coil for the number 2 coil, ran good again for a day, then the same code.
This has been going on in much the same manner since then.
I have done the following items to track this down;
1. Switched the number 3 coil and plug with the number 2 coil and plug
2. added fuel system cleaner (I have been running Chevron Premium since I got it in 2007)
3. tracing the wiring from the connector at the coil to as far as I can get in the wiring harness (I have found a couple of worn spots and have taped them up).
I was told by a mechanic at the dealer this could be a compression problem.
Any help would be appreciated.
