Tried searching and either I'm not looking in the right place or ..........
I am trying to get my car to start better with the big cam it has. Right now I have it set so the TB blade is open as much as possible and still keeps me at 0% throttle and ~20-30 IAC hot idle. To get it to start and stay running, I turn the key, crank with very slight throttle and hold it for 10 seconds and then let off. Then, it idles just fine. It will start much better if I crack the TB open more with the adjuster screw, but then I get 0 for the IAC at hot idle and 2% tps and around .9V. I was thinking that if I raise the IAC park position to a higher value, it would be equivilant to opening the throttle more at start up?????
I did remove the TPS, slot the holes and remove a small amount of material from the locating pin on it. That allowed me to open the TB blade further and still have 0% TPS when running. I really can't open it much more with out getting 0 IAC at hot idle.
Car is 00 z28, 238/246/111 cam with ported FAST 92 intake and TB.
Is my logic making sense or am I going about this the wrong way????
Thanks!
