I thought you had a cts, it will read icp.I guess I need to check into the test procedure for the ICP because I have not tested it. The injector is worth checking but the way it runs, I don't think could be boiled down to just one injector.
No problem man, I seem to have a good memory in my old age(36), I dont remember it being that good in school, lol. I've read alot of posts. Yes, there are two sides to the ficm, the power supply, and logic board. Others, as deer creek, have had good voltage reading, with bad logic boards. It apparently can make the injector stick in one position, causing overfueling or under fueling. Other than that, you've covered everything I can think of......Southend, I did not mean to disregard your statement on the FICM. Having Deer Creek state his tested fine on voltage every time, but still no good makes even more sense. My problem understanding it was that if its tests fine, why would it need replaced. Now seeing (or if I would have understood you that it may voltage test fine but still be no good) makes more sense to me. It just worries me that it can test fine and not work. I still get an ICP low and an ICP high code, and cylinder 1 contribution code. Could that be caused by the FICM. Its blowing a ton of black smoke at idle when revved then clears and blows white smoke, has no power under its own load. Unless you guys have another idea, I'll send the FICM out.
