ok...my setup is as follows. t3 tubro custom setup blah blah...my managment is dsm 390s with a turboedit map...my car idles great but when i hit the gas it bogs down real hard and then revs to 3k and basically hits a limiter. its through 2 codes. 4 and 7...4 is the crank angle sensor and 7 is the tps. i also did the mpfi swap so thats where i thought i went wrong. i double checked my wires and the c1 is going to blue green and c2 is going to blue yellow just like its suppose to. and i swapped the wires on the tps like it was said to. i really have no clue whats going on.

***note, when i started the swap, i didnt have the si ecu or distirubtor. my friend tried starting the car without the Crankle angle sensor wires hooked up. it didnt start, but would that have messed anything up?.

any clues as to what might be wrong. i have checked and double checked my wiring. seems to be just the way its suppose to.

any help is great

could the sensors and or plugs be bad? another note...when i put the stock ecu back in it only threw the Crank angle sensor code...wierd

i'd try two things

1. switch the wires on the tps again.
2. are there two white wires on the dist, sometimes those need swapping and it'll work.

is that an automated reply? you give the same reply for every person that has a problem with an mpfi swap

common mistakes thats all. and those are "free" fixes. so they're worth a try.. gotta rule things out y0.

mahcivic

thanks man ill try it

mahcivic

ok that didnt work man...when i swapped the two white wires it wouldnt start. and when i put them back it did...it didnt make any difference when i swapped the TPS wires so im thinking that sensor might be defective. any suggestions??

Sounds like you might need a new dizzy and throttlebody. BTW, don't try and change these two sensors...pretty much a futile effort.

mahcivic

how can i go about checking and seeing if those are bad? any ways?

mahcivic

wouldnt a car not idle right if the dizzy was bad... ?? my car idles great. my friend said it seems like its in limp mode. but were trying all we can to fix it
