Alright, I have a 93 VTEC, I just had my ignitor module chip (inside the distributor) replaced the other day along with the ignition coil due to car dying while driving. Now its been a week and during a 45 minute commute, my car is jumping rpms. for example, my rpm need is rising towards 3000 rpm and then all of a sudden it jumps to 4000 rpm and then back to 3500 rpm. Does this through all gears and even cruising in 5th. Anyone have any ideas? Thanks.
