Mine misfired bone stock a week after i bought it. I cleared the code and it never came back... I would do what the GM dealer would do if you brought your car to a dealership......

1- clear code
2- drive it to see if it throws it again
3- if it does... swap packs and or plugs.

Cars will throw codes all the time. I have HPT and I have scanned stock vettes, trucks, balts, all of them have codes. Some codes dont turn on the CEL for a few cycles.

 

Cleared the code, replace cyl2 coilpack, fixed the problem, Vince says the datalog is saying I'm running lean off the scam and to check the charge piping, any ideas?

check your intercooler for cracks

 

checked all the charge piping and intercooler.. from what i can see im not seeing any cracks, tightened all the clamps and did another datalog, waiting to hear back from vince, any tips on what might be making it run lean, any one experience this before while tuning? any info would be great, thanks dooooddsss

 

The cracks or leaks aren't always visible. You need to run a boost leak test.

 

Vince ran the datalog after tightening the clamps and every thing worked out fine, thanks for all the info guys
