So I finally completed my 6 bolt swap...sort of. I am having TPS issues and would like you guys correctly identify the problem.....please
I have a 90 6bolt.
PROBLEM: After I start the car, it idles fine until its warmed up then it slowly goes to 1500 rpm even with the BISS screw all the way closed. My afc shows 100% on the trottle position and it doesnt move. So the car operates on high settings at all times. 450 injectors BTW.
WHAT I DID: I used the 90 TB with the stock TPS and ISC. The ISC is plugged in and the TPS is wired into the harness (splicing). It is wired in correctly after about an hour of research so see what each wire represented. The reason I did this was because the 2G TPS on my other 1G TB would not clear the fuel feed line and rail on this 1G motor (90).
WHAT I SHOULD HAVE DONE: According to magnusmotorsports, I should have used the 2G rail and used the 2G TPS which will plug up (not anymore since i already cut shyt up). They are both 4 wire TPS ( power, signal output, signal ground and ground...or whatever the words are) and I dont understand why it doesnt work.
MY QUESTION: Will switching back to my 2G TPS and 2G fuel rail sold the problem and if it doesnt where else should I look?
