Ok thanks. Sorry for the obvious questions :) . I think i'm still going to return the part and get the cheaper one but i'll try checking with the negative test lead at ground on the chasis.
Ok so i need to measure closed throttle voltage between "a" and "b" (or passenger side and middle). That would make the voltages be opposite from what i'm reading now. however, on the plug for the tps the "C" terminal is towards the drivers side . . . "A" is towards the pasengers side . . ...
That is what I was suspecting... the dealership has that correct part number on my reciept (the one ending in 58). But the wrong one may have been put in the package from the factory or something...
Ok so what could be the problem... From my research and from the dealership i'm supposed to adjust the closed throttle voltage between B and C ("B" being the center terminal and "C" being the terminal closest to the driverside fender) to .45V or so and then the WOT voltage to 4.55-4.8V. However...
OK I had a bad tps and i took it off and replaced it with a new one from the dealership ($200). The car has been rebuilt with new bearings and a rebuilt turbo... How does the TPS go onto the throttlebody does the electrical plug plug up onto the tps or down onto the tps. i think it may have been...
thanx
Oh well, you know I fidured that it would be difficult... I may have to look into having a Muffler shop mandrel bend a custon downpipe... I DO infact have an arc welder... i may try to buy a few madrel bends from jc whitney and weld them together...
Ok. I've been searching and I can't find any real definative answer. A friend of mine has a custom made (by a muffler shop) 3" downpipe that he's willing to sell to me cheap. but he has an '86 GN . . . I have an '85 "hot air" T-type. Will it fit? It is still on his car (someone rearended him...
