end of my rope ---> here me ----> Here. Anyways it has been a great morning and it is only 7:15am. I was halfway to work when i stopped at a stop sign and went to go and it started cutting out and the rpm's would go down to nothing with the car really stumbling and then the rpms would jump back up past idle and then level out to normal and repeat it all over again then be fine for a little while and then do it again. check engine light is on steady now. the car will just creep along with no power. Before i was getting codes intermittently and it would kinda do the cut out thing every once in a while. the codes were (throttle position sensor/ pedal position higher than expected, something about adaptive fuel pressure, and lean condition. I have replaced the fuel pump with a 195 lph from SCP, I have changed the intake gaskets down to the manifold and fuel injector o rings, I have repalced the throttttle position sensor all within the past few months. It has been doing the intermittent cutout/bucking thing since i replaced the intake gaskets. Havent has a chance to check plugs yet to see if they are fouled at all. I figure it may be the TPS though it would be the third time for that, or the DIS module although that has been replaced once a few years ago and i did use the arctic silver thermal compund, or the EEC, It has been lacking power since before the intake gaskets were changed, I have also replced the cam sensor a while ago. I put new oxygen sensors on it recently. I also had a new exhaust including magnaflow hi flow cats and a magnaflow resonator with the remainder of the old flowmaster after the new resonator. Anyone have any ideas?
