1997 1500 4.3L stumbling and missing
ok so here the issues the truck will start idle and rev fine,when I pull out it does fine till it hits about 2000 RPMs then it starts stumbling and the shift light comes on. Once i shift it will do fine. Till the same RPM Range, However if i give it more gas and pass over to about 3000 RPMs then it runs like a top. problem only seems to be at near 2000 RPMS. At highway speed that is cruising RPM. so this is a issue.
We have had plugs, wires and rotor button and Cap and coil all replaced and no change MAF sensor and fuel filter and pump replaced and no change.
I need Help Im racking my brain here....
