Hey guys, have a 355 sbc, 268 comp cam, 9.1 comp, msd coil and billet dis with rotor phased, 671 blower, initial timing at 18, and 30064 fitech. Have a heck of a time getting IAC in the good. Finally got it to sit at 7 fully warmed up. Before it would bounce between 0-4, and run terrible. With IAC set at 7 I took it for it's first drive. Ran great until about a mile later. At a stop sign TPS went to .5, and IAC started hunting from 0-4 again. Took off from stop sign and it was missing and popping again. Shut it off, let it power down, and TPS zeroed. Started back up, and it TPS jumped back to .5. Took it home and parked it. Any ideas? Thanks in advance.
