Replaced parts:
1. TPS
2. EGR valve
3. ICM (Echlin brand)
4. Entire engine (all new motor from GM)
5. Injectors
6. Distributor cap/rotor (10K miles on it)
7. New coil (10k miles)
8. New spark plugs and wires (10k miles)
9. Battery
Fuel filter has 30K on it. ICM was replaced just 2 weeks ago. I noticed right away that the motor seemed to pull stronger afterwards. The alternator is suspect right now: with all electrical accessories on and giving it some RPM's it is only providing 12.9V at best.
The issue is a hesitation from a stop and today I noticed it when I was climbing a small hill...it will normally do it only for a second but up the hill it did it several times in a row (I wasn't giving it a lot of gas). The truck is running great otherwise...very smooth. When the ICM went it left us sitting on the side of the road. Could the alternator voltage cause this issue? I'm running out of parts to replace.
Thanks for your help!
