94 k2500 5.7. So it is still stumbling and surging. Not as bad but it's still there. Runs like crap before 2500rpm, then it runs like a Nascar. Stalls occasionally going from drive to reverse. Stumbles off idle. Surges 50-100rpm at idle.
What's new:
Duralast gold distributor
Napa premium wires
Temp sensor
Iac
Map
Ngk v power spark plugs
Shorty headers
Cat and cutback
Ac delco o2 sensor
Vacuum lines
Throttle body rebuild
In tank drop in pump
I replaced all the fuel lines with a nylon type line kit
It idles around 300-400 rpm in park, drops down to about 150 in gear
Also just did the timing chain
