i just got my tune done and im having some trouble still with my car. it has trouble finding its idle still...on a cold or hot start doesnt matter. i can start it give it a little help with some pedal and then it drops way down to 200 rpms then goes to 900 and stays eventually.
is it not getting enough air? i drilled a 7/32" hole in the throttle body, but i didnt mess with the screw. should i go bigger than 1/4" on the hole? i read somewhere youre not supposed to go bigger than that.

Talk to Ed at Automotive Technology Inc., he was able to staighten out my cousin's 'vette' that had the same problem. He is very sharp with EFI and has reasonable rates. His # is 757-424-1740.

Its all in the tune. Who tuned it?

I had that problem too, after my H/C, and even the tuner missed this.... There was a leak between the MAF and the TB, and once this was fixed, 'voila!
