Got a cargo with the 4.2l we thought the cats were clogged and they were so we knocked all the inside out and put them back on.
Bad part now the van still doesnt wanna go. Seems like its still clogged or timing is off. Checked the throttle position sensor it was gummed cleaned it. That helped but still is doing it. It just wont throttle up and hesitates real bad like maybe timing or its gummed up somewhere else. After about 5 or so minutes the headers will start to turn red "crazy" likes its lean.
Any ideas would be great we are kind of thinking maybe the cam sensor and syncro not sure any help would be great. No codes showing either
