Default Re: Misfire at High Speeds

Hey guys, thanks a bunch for the responses. I have an android phone and will look into the dongle and Torque Pro. I left out the injectors, but they are new. I going to change the MAF and MAP. As for the TPS I have 74mm throttle on now, but still have my original throttle. I will swap it and see what happens. I'm going to perform a back pressure test to see if the exhaust has any blockage. I certainly hopes it's not wiring also. Thanks again for the responses and will keep the post updated as I work through this to find an answer and I will update with the resolution.
