i've played w.idle adj. plate and screw on tb, tps, egr hooked,unhooked(though not func.)
guy at speed shop said pull chip out, I did it helped alot
this whole time idle being the only prob, at 1100, at 1700, or surging from 1000-1800. car drives good, bucks like typical E303 below 2000 on decel(ie. 4gear,30mph,3.73), somehow pulls hard to 6000, falls off a lil but pulls pretty good to 6500

it almost seems as if its retarded, but I've been running a stock cam for the last 2 years(in THIS car)so...

is this as worse as it gets(ie. get x303w/1.7's or bigger and live w/surge?)

oh yeah, its E303 w/1.7's straight up, heavily ported,milled 289 heads, longtubes 1 5/8, 3"exhaust, performer intake-ported up,lowercleaned up, 70mmtb,elect fan, etc.etc.
