Thanks for that info on the IAT.
I pulled the linkage off at the TB and watched the scan tool while manually opening the throttle blades. TPS voltage at idle was .54V and started increasing immediately, but would raise to .84V before the TPS % started to climb off "0"...Not sure if this is significant or not.....?
Looked over wiring and connections for TPS, MAP, IAT; checked the distributor cap and rotor for corrosion; checked the vacuum lines for cracking or kinking etc,
Next steps?
I am going to plumb in a mechanical fuel pressure gauge and closely watch that....looking for other ideas here. Summer is coming and I am getting frustrated lol.
