Redid my wiring harness again just to clean it up and shorten most of the wires. The car is a 1973 Camaro 5.3/ turbo 400 had the motor installed by one guy and wiring harness done by another. The wiring harness guy also street tuned it. Ive driven it like 1500 miles and hated the half *** harness so I redid it. It didnt work so i redid it again and then i wasnt completey pleased with it so i did it again. I also have changed the head and gasket since i broke an intake bolt off in the last one.

ANYWAYS heres the codes in order by which they came.
P0102
P0135
P0155
P0101
P0102(again)
P0134
P0154

Car has good voltage on all the wires on the MAF and the o2s. The car has an LS3 Maf in it. Again its ran great before and this has to be the most stressful thing.
Desperate to drive this thing again....


Any help is greatly appreciated!

MAF has 12v on the pink, good ground, and 5v at the yellow
O2s have good voltage and ground and around 10ohms at the heater pins

All three sensors are new so i highly doubt they are bad. I had a code for P0102 and i thought i fixed it when my IAT was at -39 and i fixed it to go 33. But i guess the code came back and the IAT wasn't the problem
