General inquiry: Either of you wouldn't happen to have moved your battery to the rear of the car? If so, then there may have been a significant voltage drop because the battery ground is further away from the block, sensors, ECU, etc. and may be causing some issues. You may want to run some separate 4ga copper wire lines from the block, firewall, ECU grounds, and transmission to the negative battery cable. The steel chassis is a relatively poor conductor as compared to heavy guage copper wire.
Probst....p.263-266 KOER codes
Forest Green GT
34...Insufficient EGR flow/Excessive exhaust back pressure; or EVP voltage above closed limit (SONIC)/PFE sensor voltage high or out-of-range
67...Neutral Drive Switch (NDS) circuit open; A/C input high;Manual Lever Position (MLP) sensor out of range
85...Canister Purge (CANP) circuit failure
95...Fuel pump secondary circuit failure
Those are some odd-balls. Perhaps something is disconnected, cut, or the connections are bad. 34 and 85 may be due to the air-pump and canister purge removal.
22...MAP/BP out of Self-Test range
24...ACT or VAT input out of Self-Test range
35...EVP/PFE circuit above maximum voltage
51...ECT sensor fault or circuit open
53...TP circuit above maximum voltage
54...ACT or VAT sensor fault, circuit open
66...TOT sensor input is less than Self-Test minimum OR VAF circuit below minimum voltage(E4OD) OR MAF circuit below minimum voltage
No wonder the car is running poorly...those are some key components...MAP, ACT, ECT, etc.
Disconnect your battery. Double check all your connectors, including the two 10-pin connectors, and the EEC connectors for moisture, corrosion, proper contact, etc. Sometimes the pins are bent slightly or are not in full contact with the female connector. Use some spray electrical contact cleaner (Radio Shack). Double check your ground situation if you've recently had the battery moved or have had work done on the car. Once you've got everything back together, run the KOER again.
Many of these codes are uncommon, especially unusual to have the ACT, MAP, and ECT codes all at once, so I'm suspecting connection issues with at least some of them.
