Your TPS might be working, but if its not on the right position, it would make the car run crappy like how your car sounded right now..

 

Wrong. TPS should/never reads 0% on idle or cruising. If it reads 0% then you have a problem...

 

Yes tps should read at least like 7% sometimes all the way up to 16% or even a lil higher on idle or with car not running. Are you on the stock ecu still?

 

I didn't really think that one through...with all my years of tuning and mine never being zero just spat that one out.

 

does the car have a cat? if it does then it probably blewout. if it doesnt have a cat then something is wrong with the turbo...turbine housing?

 

bump! my new COP should be coming in today! i dont no for sure because SparkTech doesnt pick up there phone ever... dont have a tracking number nothing. but they said it left there place Thursdays thats all i no. 3 day shipping it should take.

 

UPDATE: it is not the COP! WTF

 

Have you checked/replaced both cam position sensors?

 

yes i have. i just ordered a omni 4 bar map sensor.

 

This is a really strange problem. It's got me stumped. I can't seem to stop thinking about it, I can only imagine what you are feeling.

 

bump for part 3! was not the omni 4 bar

 

i give up.. i have not a clue what this could be

 

Is your boost gauge tied in to the FPR vacuum line? Have you switched out the FPR with another one? When my FPR failed the car was pig rich and wouldn't run. It flooded the motor out. Try borrowing someones and see if that helps.

 

Take off your speed intake temp sensor that you use for speed density. Inspect it and clean it with CRC Maf sensor cleaner

 

the boost gauge has a T connecting the boost / FPR to the intake mani... i no some people say let the FPR run a line by itself but it should just magically not work. Its been like that for awhile.

I tried 2 different stock FPR's one was brand new other one was working on my car before i switched to automotive then back to stock. so they should both work.

I HAVE A GUT FEELING IT IS LOW FUEL PRESSURE THO. i sold my aeromotive so i do not have a gauge to see what it is. BUT im not sure and done wasting money on guessing. not spending a dime more till i no what it is.
