Hey guys...suppose I'm in 3rd or higher gear and the RPMs are under 3,000......when I attempt to accelerate the car seems to buck pretty violently.......almost like the fuel shuts off or half the cylinders don't fire. Once it gets around 3k this stops. I check my secondaries, they're working just fine.
I'm not getting a check engine light unless I do this on purpose for an extended period of time.
I have new spark plugs, FMS wires that are 1 year old, a 1 year old coil pack, all new underhood wiring <1 year old, new Delta Pressure switch............
Any ideas??? The car seems to run fine in the upper rev range.
