Not sure where this goes but here goes. I have a 94 X with the 4.0. I have cleaned the MAF, changed the plugs, air filter, TPS and IAC. I don't have a loping idle anymore, but it would only idle at around 400-500rpm(I raised the idle manually). My EZ-READ 2000 found KOER codes 412(cannot control RPM during KOER high RPM check),and 411(cannot control RPM during KOER low RPM check). I was getting a MAF and TPS codes before I changed/cleaned them. What should I look at next.
P.S. No obvious vacuum leaks,loose wires, ETC.......
