hey boys, got a quick one for ya. what year did the TPS become non adjustable on TPI motors? i think it was 90 but i'm not sure. (i need to know for a report i'm writing about TPI) also if you guys know where i could get a picture of an ECM, a fuel injector,a fuel rail, and pictures of some various sensors it would be greatly appreciated. i don't have a scanner.

I thought they were always adjustable, until the motors changed to LT1's.

Hope i helped, Curtis

 

I also think it was 90, but I could be wrong.

I know 89 is adj, and from what I have read 90 and up is not.

 

I have a 1991 TA 305 TPI and mine is adjustable.....hope this helps..
