My jeep starts but rpms fluctuate dropping to the point of almost stalling and then climbing to 3, 4k and does that rapidly. Stalls after getting on the gas a few times, and when it does stall it sounds like its sucking air. Its a 1998 jeep grand cherokee with a 318 5.2L v8.
Have replaced the timing gear and chain, plugs, wires, distributor cap, and the catalytic. What the H3#* else could it be?
