My good amigo has trouble when no gas applied. Rough idle when sitting at a light or just as go into reverse. Must give the extra gas. Have done all the cheaper things - new plugs, wires, O2 sensor - but still no change. Ditributor, starter, alternator all good. Wondered about the IAC or possibly a baffle blockage in the muffler? Mechanic and I go through each fix hoping it will remedy this situation. Suggested sending in 'the brain' for a revamp but thinking of that as a last resort since not sure if electrical. Touch of hesitation at higher rpms, 60-70 mph, but not feeling it's super critical so far here just worry about the wear on engine as symptoms persist. Thanks for your expertise ! Amigo93k
