IAC and TPS are both new. When i bought the rig the last owner had screwed up the ECU plugs so horribly I was forced to cut them out and butt connect donor plugs in their place. Even though they are marine grade heat shrink connectors I believe the problem (bad crimp) lies therein. It was really tight working in there. I had to remove the front seat and the center console just to squeeze my head and arms under the dash.nThe heater core is ready for replacement and since i'm taking the dash out anyway the plan is to remove the butt connectors and solder the ECU plug wires for better conductivity.
I've noticed under the hood that sometimes if I move a plug the engine will falter. I know a few are past their prime and have breaks near the plugs and are surely corroded within - hence the impending "wiring tune up". I have an old beat up harness. Maybe i'll take the plugs with me and just start checking other vehicles at the boneyards. New kid, too much work and moving into the new place has all my time taken up. I was hoping someone might have compiled a list of good donor vehicles for plugs. If I find them I'll compile a list and post it.
The reality is that the hesitation is so slight and so intermitent it is barely noticeable. I rebuilt this thing from the ground up so I can be a bit anal about the little things. No sense in stopping at anything less than perfect after all the time and energy invested. Besides, I love this rig and it deserves all the tlc i can manage.
Thanks for the info guys - keep it coming. <img src="/forums/images/graemlins/kewl.gif" alt="" />
