Can a bad injector cause a P0352 error code?

Okay gang... my 5.4L starting running rough about 6 months ago. I replaced the COP on #2 and all was well. Now it is missing under load. I went to AutoZone and the error code was P0352 (#2 cylinder ignition error).

I put a new COP (again) and replaced the plug. No change. It still misses. So my question is, can an injector cause the missing and error code? If so, how hard is it to replace an injector? (I have replaced all plugs before and COPs in the past, lower ball joints...I can spin a wrech or two.)

Any help would be greatly appreciated.




Vehicle history: 125K miles, rear lights came on with no key in the ignition. Wiggled the wiring harness under the dash and light problem fixed. Mechanic said I might have to replace the harness.

No, the injector cannot casue this particular code.

P035x codes indicates that there is an electrical fault with the COP. You might have a faulty harness, connector, or even a bad PCM.

More questions...

Thanks for the info Steve.

What's a PCM? How much? Where is it located? Is it hard to replace?
