Bought a 96 gmc k1500. Changed plugs, wires, cap and rotor. Went to tighten cap and broke plastic dist housing. Bought a new dist from oreilly. Marked locations and installed new dist in relation to old one. Ran scanxl and set cam retard to ~1degree.
Truck seems to idle a little rough. Not bad but I can feel it in steering wheel and seat. Here is the data from 2 mile drive with a few wot pulls. Any ideas? Only thing I can think of is dist is one tooth off. I am using 87oct fuel. No CEL. Does the spark advance look good? Are the amount of misfires normal?
