1997 FZJ 80 145k miles
About 1 month ago I cleaned my MAF sensor because I had an intermittent miss at idle and around 1800 RPM while driving. Everything was fine for a day, until the miss came back along with code po120. The 80 also began to accelerate poorly when cold. After it warmed up, the acceleration seems fine. I checked the resistance of the TPS according to the FSM and it was still good. I cleared the code, and it came back with the same symptoms. I cleaned the MAF again, which helped, and the symptoms came back.
When it is cold and I put the gas to the floor it poorly accelerates. If I manually change the gear selector from D to 2, it downshifts and accelerates well. Using the PWR button does not change anything. Turning on and off the OD button does not help. When on the highway and giving it gas, the trans will down shift, so I don't think it is the kickdown cable.
Do I have 2 different problems? Am I looking at a trans problem or is the TPS bad, but not bad enough to be out of specs?
TLDR: My 80 accelerates like a turn when cold. It throws TPS code for a TPS still in spec
