Hello,
New member here from GMT400.com, I do notice a couple familiar names from there on here.
I recently went to an 0411 on my 1996 Chevy K2500 with a 454 and a 4L80E, I received the pinout from LexTech, as well as his kit with the 0411 and connectors.
I followed his pinout to a T, although I did make a few mistakes such as not adding in the wire for the EGR and not properly putting the VSSB wires together, but both of these have been corrected.
It idles like crap now, it used to idle 750-800 RPMs, now it's 550-600, shakes like it's misfiring, wants to stall out when I put it in gear, and it's throwing 3 codes, a P102, a PO341, and the P1336 which I expected the crank relearn code.
I've had someone who's done the swap tell me the CMP code could be related to the CKP which does make sense, but I'm lost on the MAF code; I did clean it but it's still running rough.
I've checked my pins 4 times now, and I'm about to check them again, anyone got any suggestions? I don't really have a means of datalogging, I've got a crappy Harbor Freight scanner that shows me some of the information but not a lot.
