    what size fuel injectors?

    my 01 yukon has the 5.3 and a whipple supercharger pushing 8 psi max im leading to believe injector #8 is bad so im replacing it. however i THINK the injectors are the stock size since this whipple system is the one that has the two additional injectors out front. can anyone back up that...

    p0300 and p0308

    I know I'm bombarding you guys I just switched the plug wire from 8 to 6. and now the code went from p0308 to p0300 and is idling rougher and if its in park and you rev it a little it drops back down to like 400 rpm and bogs a little. so new plugs and wires and see where it gets me?

    p0300 and p0308

    I moved the coil and spark plug to #6 last weekend no change for whatever reason I forgot to move the spark plug wire. do I need to just plug the coil harness into 6 and 8 and 8 into 6 or cut and splice it? I may just change it out with a new one anyways since its mentioned. also let me explain...

    for those following this thread I tried today carb cleaner around the intake, no fluctuations in rpm so I don't suspect a leak. I also took out the #8 fuel injector, It really did not look bad but I cleaned it best I could and put it back in. with no results. still blinking ses light the only...

    Will this driveshaft work?
