Surging 1989 Cherokee Update
It looks like the surging problem is gone under normal everyday driving, but is still there occasionally when you turn on the A/C.
I replaced the TPS and calibrated it.
Cleaned the IAC. This piece is old though.
Cleaned and tightened ground cables to the engine and firewall.
Thanks for all of the help keeping the old Jeep Cherokee on the road.

We Renix guys need to help each other out. Got a hit from another forum which suggested a new O2 sensor. So if it keeps acting up you may consider that. Good luck mule.
