So I picked up a 2003 reg cab long box 2 wheel drive with the zf6 manual. I got a really good deal that I couldn't pass up. truck has 262k on the clock but runs really good for the most part. Got it home and saw the check engine light on. hooked my scanner up to it and saw egr code but that was due to the wires were broken going to the valve. Replaced the pigtail and put in my buddys used egr valve for now till I get my delete kit. but looked in the intake and it was caked in soot and sludge looking stuff. been driving it hard to try to clean some of it out. will clean it out when I take the intake off to do my delete. Then I also had a code for icp voltage low and and cmp sensor code. I will get code numbers tomorrow after work. But I will have it where I can drive it and it will run great no problems. but then I will be sitting in my driveway or the parking lot before work and it will idle good then start idling like it has a crazy cam in it but looking at the scanner the rpms don't change. (Truck could be cold or warm) I check the icp and it will drop down to almost 600 then as high as maybe 680 at idle. But its jumping all over the place. Is the icp starting to chit the bed or is there something else I should look at? My buddy has a used icp that I might throw in just to see if its the sensor itself and check wires while I'm there. sorry for the long post but just trying to paint the picture for you guys. Any more questions you need to know please ask. I would like to really figure this out. thanks for your help.
