I have a 91 Integra LS. I was driving it hard, harder than I usually do, the other day b/c I was in a hurry. I noticed that the tach needle was bouncing from 3k to 6k and then all of the sudden to 0 and back to 3k. I also felt a jerk like the engine cut off for a second and kicked back on. I got worried so I drove the speed limit. The ac was also on full blast, I don't know if that would be part of the problem. Later on that night, it did it again and more often than the first time. This is new to me so I am stuck on this. I had some parts replaced recently such as the ignition coil, distributor gasket, main relay. This was done before 100k mi. I also had the major service done at 90k including a new clutch and flywheel, timing belt and water pump. The mileage is now just over 100k. I am not sure what's causing this problem. If someone out there knows or have experienced this please help a brotha out. Oh and by the way, the engine stalled out but after a few minutes it started up fine and ran fine for a few miles, then the jerking of the car, engine shutting off and on, bouncing tach needle comes back leaving me to park it off to the side stranded. Thank you in advance to anyone that can help.
