Ok so I've had a check engine light basically since I got the truck back together and it was because I had the IMRCs taken out but they were left in the tune. I decided to check them last night and there were some different ones this time. They were p0171 and p0174, lean bank 1 and 2, p0704 clutch pedal position switch malfunction and p1121 tps inconsistent w/ maf. Now the clutch pedal I assume is because of having to change the clutch master cylinder and I didn't get the connection back on all the way or something like that. It still works and allows me to start the truck and everything so I don't think it's too big of a deal. The others I'm not quite sure about. I think it might be becaise the truck still doesn't have its final tune but wanted your guys' input. Could it not being tuned exactly right cause those codes? What about the TPS inconsistent with the MAF? Does that seem more like the TPS or the MAF are going out? I'm going to clean the MAF cause I haven't cleaned it yet and see what that does but any other ideas as to the other codes? Any input I'd really appreciate.

 

With the 0171 and 0174, the first thing to do is look for vacuum leaks - those are indicative of unmetered air entering the intake.

 

I'll do some more checking for vacuum leaks. Thank You

 

Found a leak where the gasket had been leaking around the IAC on the intake and fixed that and so far seems to be working properly. Thanks for the help guys. I'll let you know if the problems come back or not.
