A20 LEE 0 Posted July 4, 2004 Car idled perfectly but had big bore TB, new distributor and new fuel reg fitted and now the car idles at about 650rpm but some times rises for no apparent reason, rises to 1000rpm, some time the revs don't seem to drop as quick to tickover on blipping the throttle, ie. they fall quicky to 1500 rpm then slowly to 650rpm. ideas?
