I'm Awesome
1996 K1500 vortec 5.7
New dizzy, plugs, wires, mpfi upgrade and throttle body gaskets, cat (need to install the other because it's started to rattle/ pos flowmaster cats), timing chain has 6* total slack, new fuel filter.
Starts up right away, fuel pressure may be a bit low/ 56 psi at key on, 46 psi at idle.
No codes.
Fully warmed after driving 15 miles so I plugged in my scanner to see what was causing a short lived but high idle (1500 rpm) when truck is put in park. No such luck, idle normal. But I have weird numbers and still have major ignition retard in #1. Truck runs really well but I can feel a miss or slight 'bump' at stop light or idle. Following data is from last mile and park in driveway.
