Well, first things first. I checked my codes and got 2 tranny codes, from the swap, and knock sensor code. Mind you, I have budget y pipe and a 2.5" test pipe. Fed spec, and I didnt get an 02 sensor code?? I have no cat anymore. Just odd. So I changed the knock sensor, and after 300 miles of driving code was still there and car was still running super rich. On top of the fact that its running rich from the injectors I put in prior to the knock sensor going bad on me. I'll just wait til I swap in my 96 5spd ecu I guess and maybe the code will be gone and car will run better.

Second weird issue that bothers me the most. I can tap the gas pedal and come off of it quickly, and rather than revving up when I tap it and let off, the car just doesnt do ANYTHING, then I can count like 2 mississippi's and then the engine will rev up. WTF? I can punch the gas pedal in neutral and get out the car and then it will rev. What's causing this huge delay? When I engage in first gear at a light I have to rev up to like 3k just so i know that my car is ready, and as its falling i keep it steady at like 1.5k and come off the clutch. But if I hold the gas pedal down to get it to go up to 1.5k, it will not go for like another 2 or 3 seconds.

Is this the throttle position sensor? Running TOO rich can cause this? (I'm supercharged running 370cc injectors, running rich and NOW the knock sensor is causing me to run rich also) Thanks for your help.

 

Did you reset the ecu after replacing the KS. Your sencond issue sounds like hesitation... maybe a bad MAF? I know some other guys were having hesitation issues with no codes and some just replaced the MAF which seemed to cure it.

 

Check and make sure your Throttle Cable isnt binding within itself. Check and make sure its not kinked anywhere as well.

Theres no way it should take that long for it to rev. Something is wrong.

What disc are running in your fmu ??

well I know my friends' 240's run pretty rich but thats because they didn;t replace their 02 sensors after swapping SR's in. Maybe that for the richness, iunno. But as far as the delay, MAF? TPS? FMU? I don't know why you still be getting a KS code (check wiring?)

 

Cartech FMU, Z32 injectors, SAFC. That's all I have.

There seems to be a good amount of movement with the throttle cable. Seems normal. TPS can cause this possibly? I will reset the ECU, and i'll borrow a friend's maf. Thanks for the advice ill report back.

 

I know i'm late just wanted to say it was a bad MAF.

 

I knew it.

 

yup at least you found it out without replacing a ton of stuff..
