I am currently completing a 2jz swap in to my MKIII, but I'm having a problem.
First what I have.
This is a stock 2JZGTE out of an Aristo, it's been put into my 1987 MKIII and bolted to a R154. Everything is together except the exhaust. At the moment it's dumping out of the y-pipe.
Now the problem. It's starts immediately and initial idle starts out at 1600 RPM, but over the course of 30 seconds the idle raises to 2100 RPM and stays there until the engine warms up. then the Idle starts the pulsate rhythmically between 2000 RPM and 1500 RPM. The car drives great except for the high idle. Now I've checked the ISCV(Good), MAP(reads perfect) and TPS(Seems good). One thing that does seem off is the E2 reference for the TPS, this is supposed to go to ECU ground. I'm reading 69 to 72 ohms on this wire. Is this normal? What should the ECU ground reference be? Any other ideas about my idle problem are welcome.
