ok guy's,
I have a 2001 yukon 2wd that I have lifted. I have put a 315-50-24 tire under it and added a 456 gear. After replacing the gear I had a problem with no power and it turned on the trac cntrl light, would not move unless I turned off the trac cntrl. I installed an edge cs programmer which has worked for awhile but brake and abs lights were on. This passed week I learned when I floor the peddle I get a check eng. light with a p0131 & p0151
I also have had p0141 & p0171 and they make the truck run bad. I have replaced b1s1 02 and the maf sensor. We also tried to reprogram the ecm with a tech 2 with the latest update and tried changing the tire size to a bigger tire which made things worse. can someone please help ?
