4.3 Vortec Swap Help
I have a 1991 S10 that had a 4.3 in it. I bought it and swapped in a 4.3 Vortec motor out of a 2000 S10 Vin-W. I swapped the motor wiring harness and pcm, along with all the smog stuff.
The problem I am having is I keep getting these codes for the O2's, P0199,P0135,P0147 and P0155. Those set first and then a week later I got P1133. I installed all new O2's when I did the swap (3 total). The freeze frame data shows it always sets under about 10% TPS and about 40-50 MPH.
Any Ideas?
