alright i got the radiator and everything in it, different tps that only reads 4800 ohm at WOT, different afm, everything good. i could get the ecu to reset so i'm letting it set overnight and tryin it tomorrow but it still did the same thing. i'm startin to think i'm having fuel pressure problems, maybe the stock fuel pressure regulator is bad? anyone ever heard of that happening?

 

ya........ok

 

I had the same problem on my S4. I couldn't fix it so I put my carb on. I figured out later that I had a vacuum leak. I missed a few lines somewheres.

 

i've pluged every vacum line i could find as i put the upper and lower intake on it any idea if i might be missin one and where?

 

Alright i just tried something else. I tried startin my car normally with everything plugged in, and it ran the same (hesitant, won't idle, etc). Then I tried unpluggin the tps. And it still ran the same, is my tps bad? Its throwin code 12 which Throttle Sensor (Full range) so what do I do to fix this???

 

hello can anyone help me???

 

Have you read the sensor inputs at the ECU yet? Might not pinpoint exactly what's wrong, but it'll sure as hell tell ya what isn't wrong...

Don't know if it'll help, but the only time my car has ever acted like this through the years was when I had a bad primary injector- troubleshot the bitch for 2 days straight...

 

how do i do that wayne?

Hopefully that'll work. If not, search for "Troubleshooting your car from the ECU", or something like that

 

ok well here these are the check engine codes that are coming up on my car, alot of the stuff i removed, maybe i have removed something i need u tell me. here they are:

20 – MOP
25 – solenoid valve (pressure regulator control (PRC))
26 – step motor (MOP)
30 – split air solenoid valve
31 – solenoid valve (relief)
32 – solenoid valve (switch)
33 – port air solenoid valve
34 – solenoid valve (bypass air control (bac))
38 – solenoid valve (accelerated warm-up system)
40 – auxiliary port valve
41 – solenoid valve (variable dynamic effect intake control (vdi))

I'm running a premix so i don't have the metering oil pump on there and i know it will run in limp mode or what ever its called, but anything else?

 

sounds like a vacuum leak

 

how do i go about checking this? should i just look up the vaccum diagram in the FSM and follow all those? will that show all the vaccum lines, etc that i will need to check or is there some hidden that i wouldn't know about?

 

ok got it running any everything, beside it won't idle under 3500rpm? what to look for now?
