  • 2.8 that misses under load

    I can't seem to figure it out. It only does it when you give it about 1/2 throttle or more and it goes away once the RPMS get above 4k but, comes back when the engine shifts and the RPMS are below 4k. I already put new wires, plugs, and coil packs on the car and have run a ton a fuel injector cleaner in the tank. Any suggestions on what it could be because i am drawing a blank here.

          Any codes?

          Is it missing or jsut stuttering? Maybe a fuel problem under load?

            No codes (no SES light) and it does feel like a studder or miss if you will. You can hear it in the exhaust like one of the cly are not fireing right when he takes off. I was thinking te TPS but i really dont want to throw parts at the thing. Its bad enough i put 90 bucks worth of coil packs on it and it did not take care of the problem. :mad: Thanks for the help tho, anymore suggestions? It is worse when the car is cold and i can't even rev it untill it warms up alittle. It sort of stumbles on its self untill the temp goes past 150.

              check out the crankshaft position sensor. I had that go bad on my 2.8L beretta here recently. Also replaced the fuel filter too. try those 2 things first. (cost shouldbe under 40 bucks for both) [img]graemlins/thumbsup.gif[/img]

                Do you remeber why you replaced the crank sensor? I am thinking about replaceing the fuel filter and that will probly be the next thing.
