Re: 1991 dodge spirit R/T problems while running!
What do you mean WTF!!!?????
There are no WTF's until the problem has been diagnosed, not hit with the parts dart.
If the problem still exists obviously it has not been found and corrected.
You replaced a lot of parts but have yet to connect a scanner to see sensor parameters.
1)What is the controller seeing?
2)What are actual AIS steps at high idle..0 or stepped out???
3)What is TPS reading at closed throttle?
4)What is base idle reading?
5)How does the car idle with the AIS stepped in and removed from the equation?
6)You replaced all vacuum lines...
A)have you eliminated vacuum components as an issue, cruise servo, brake booster, HVAC issues, etc.???
B)Did you splice the existing harness...sliding rubber line over smaller nylon line, never seals correctly.
