Top swap throwing some codes
 

Got my top swap done this weekend and have some issues. Car runs great but will shut off for no apperant reason at times. This occurs about 10-30 seconds after I am 75-100% throttle and let off at about 60 mph +/-. I get a P0101, P0650, and P1670. The car will not start after this happens so I either have to disconect the battery or use the key fob to lock then unlock the doors and it starts up and runs fine. Anyone have any ideas? I have a ZZP 1.0 PCM.

Sounds like you're having some security issues, did you email zzp?

p0101 = Mass Air Flow(maf) circuit range/ performance problem

Here is a link P0101 Trouble Code - Mass Air Flow (MAF) Circuit Range/Performance Problem

P0650= Malfunction Indicator lamp (MIL) Control Circuit

here is a link DTC P0650 Malfunction Indicator Lamp (MIL) Control Circuit

p1670= dono how to explain that one

heres literially one of the only gm links i could find
P650 and P1670 after Intense PCM and 180 stat install - GM Forum - Buick, Cadillac, Chev, Olds, GMC & Pontiac chat

hope this helps, sounds like you should check your conections

You have a ZZP 1.0 but was that set-up for a top-swap or did you have it before hand? (silly question but it could get overlooked)

You have the headers and rockers and CAI, modification wise you should be okay to run the stock pulley so all I could think is that the tune is messed up.

Going to email ZZP on it right now. Just wanted to make sure I wasn't over looking anything obvious.

Yes the 1.0 PCM is for a top swap, I didn't have it before hand.

Budsjlm - Thanks for looking that up. Couldn't find anything really good on those codes.

I'll let you know how I make out. Kinda worried that the P0101 isn't related to the other codes...hoping its not something major. No CEL comes on either when it shuts of which I find funny.

Found out that heat is causing this issue. If I run with the fans on the car doesn't throw the P0101 and it doesn't shut off. If the fans are turned off and it heats up the engine turns off and I get the P0101. Any idea's what to check?

I got a new PCM from ZZP today and it got rid of the P0670 and P1670 codes as I suspected it would, but the P0101 came back today but didn't shut off, just studdered for a second. It was cold here tonight when I got to try it so the engine didn't get over 170* so I didn't get a good test run in. If anyone has idea's what I chould check to see if its overheating causing the engine to shut off I'd appreciate it

Have you cleaned the MAF yet?

Yep, and tryed a second one. Thinking it might be ignition related, I have new wires so I'm going to swap out the ingition module and coils tonight as I found on another forum a similar issue and that solved it.
