AFR 165's, TFS Stg 1 cam, GT40 with exploder lower, 75mm throttle body, spacer, 73mm vortech MAF, egr disconnected.
Car runs great (like a scalded ass ape), and idles great until good and warmed up. About 5 or so miles, it starts to die when you let off (push in clutch and return to idle). It tries to catch, but if it can catch, itll surge, sometimes dying, sometimes not.
Originally, i had codes 15 (prolly from the hypertech chip), 31 and 67. Wouldnt idle at all, MIL stayed on, and was VERY rich. Pulled IAC, cleaned, and checked the EGR plug (have sensor plugged in it to fool the puter). Reset codes, and immediatly ran fine. No more rich smoke, more power but still this nagging return to idle issue. No more codes (other than 15) atm.
A couple people (one mustang guy) has suggested maybe the computer needs some learn time. Ive done 20 or so miles. It seems like just maybe its gotten a little better, but might just be my wishing. Coiuld it be this?
ideas?
