No matter what speed or rpm driving - the rpm will drop from the current rpm to 1000 rpm (for a less than an second) and then return to original rpm resulting a "jerk" in the transmission. No engine light comes on. Problem is sporadic, occurring at any rpm or regardless if the A/C is running or not. Took the car to a mechanic who checked spark plugs and wiring and found no problems. Could it be the fuel filter?
