Ok, I just had my 5 year project tuned and driving< I would say finished but they are never finsished. Any ways two weeks of driving mkaybe 50 miles my motor starts to cut out @ roughly5500 rpms, just about starting to spool and the motor starts sputtering. My first thought was ignition was fried. So i replaced the cap, rotor, wires and plugs with OEM, one by one and with every one it has progressed with me now stuck not able to spool and cutting out at low rpm's i have parked it with scratching my head except in the morn im throwing in a new fuel filter. I know this is a long thread but om trying to be specific with leaving out lots of engine/setup info but looking for more solutions. any questions about setup i will gladly answer, but any ideas would be greatly appreciated, thanks.
