- The tachometer is driven by the ICM.
- The cam sensor plugs into the ICM.
Hey, there'* three of your issues right there!
Now, before you run out an buy a new ICM, let me stop you and say that your fuel injectors aren't connected to it. However, if the computer is seeing erroneous readings and trying to adjust fuel injector timing to match, that could cause the P1200 code.
Assuming that your battery cables, the ICM'* 20A fuse, and wiring harness are all good, I'd look into the ICM. Thoughts, everyone?
Dude I would seriously by you a beer lol I changed out the ICM with another one i had, replaced the wires on the spark plugs for good measure. And after almost 100 miles of driving still no issue!!! I made sure to clean the plate under the icm real good and put a coat of Di-electric grease on it, i assumed this was a ground and the plate had crap all over it.
I really appreciate the help from all you guys. Things running better then ever right now.
