I have a misbehaving 1995 camaro z/28 with a 4l60e, stutters and stumbles at part throttle cruising. The car just got a freshly rebuilt 350 with a cc 503 cam, egr delete, air pump delete, electric water pump, new opti, hooker long tubes, purple hornies, and a few other goodies that make relatively no difference, hi po ls7 lifters, recommended comp cams springs/retainers/locks, and hardened pushrods. oil pressure is good, fuel pressure stable, new plugs, new wires. still running narrow band o2s added a couple of degrees of timing through most of the map (4 at most) changed the fuel cutoff so it stays alive at a stop. it got a small port/polish on it and adjusted ve accordingly as far as ive been told.
TLDR: car stumbles cruising with small throttle changes I.E. letting off throttle and getting back on gently. have tuner cats and eehack. can send a datalog via pm or email if anyone can help me.
search is difficult to use so I made a new thread
