Doesn't shoot out dark smoke or anything when I start it or drive it, although you can see from tailpipe that there is a fair amount of carbon buildup there. Had trouble passing smog test twice before. Before you spend money on a rebuilt engine, we would suggest scanning the computer for fault codes. The compression numbers, although not ideal, are not that bad. Tore everything down, got the head milled, put everything back together.
Timing belt is absolutely on correctly.
Vein on dist. I really appreciate any help. Well, seems time to go back to basics. Check the compression, check for the proper amount of fuel and spark at the right time. My wife was driving her '96 Rodeo 3.2L V6 and the speedometer quit working.
