The tps should be .40-.42 and iac 20-30 engine warm at idle.

How much boost? What fuel?

Your high BLM at idle tells me there is either a big vacuum leak somewhere, or the MAF is bad (reading too low).

[1fast6]

what is your FP reading at idle with line off? what fuel system are you running?

 

[unobetr]

[Black Power]

just made a pass down the road... heres the scan master recall

714 19.9 049 034

714 being the 02 MV and 19.9 being KR?



If that's running the alky, there's something goofed. That's a lot of knock.

As Eric mentioned, you have really high blms, should be closer to 128.

Do you have floor mats or is your tps just out of adjustment that much? I couldn't get full voltage with my floormats in so I either scoot them way back in the floor or I take them out.

 

[unobetr]

i dont think its knock.... this is a full, like... hmmm.. jumping.. its not detonation.... unless what i think is detonation is completly different from what i think.. ( i think detonation sounds like a ... valve rattling.. ??? )

 

[unobetr]

could my coil pack be going out??? and.. i dont know what kind is on the car. any ideas?? heres a pic...

the big vaccum line off the top of TB it goes to the intake.. does that have to complete there?? mine is just plugged!

 

[unobetr]
