Hey guys. I wonder if anyone has ever run into this. Now consider i do have mods, Mark V!!! MAF, 30lb injectors, superchip, cold air intake, 255 fuel pump, and roller rockers, and i switched from an auto to manual and i still have the existing computer and harness, but the chip was said to be reburned to suit for the manual transmission. Does anyone think that my rapid idle on start up (0-2300 quickly) has anything to do with my existing auto harness. And when i try to plug my speed sensor up, when i hit about 40mph, my insturment cluster says im going 110! Or does anyone think it has to do with possibly my IAC. I have recently set my tps at .94 and it performs great, i thought maybe that was the case but it doesnt seem to be. So if anyone has any info that would be great...thanx!
