hi i have a 2006 mustang gt with an auto trans. my mods are an edlebrock eforce kit with a 3.5 pulley, hot rod cams, offroad hpipe, borla ataks, BA5000 MAF, msd master blaster coil packs, autolite HT0 spark plugs, 39lb injectors, walbro 400 fuel pump and 4.10 gears.
I've been having issues for some time now where sometimes on start up the car will have a jerking idle varying between like 200-300 rpms and it'll rock the whole car. Sometimes it will idle fine and occasionally miss or start struggling to maintain idle and the engine will start shaking real bad may or may not come back up and if I rev it up itll idle back down and die... while driving it seems fine 90% of the time other than when the car downshifts and I give it gas the plugs will start breaking up real bad or when im slowing down itll idle weird till it adjusts. It pulls great at WOT ive been to the track and it runs high 11s. I've cleaned the maf/throttle body, I've changed to multiple TPS sensors, and done KAM resets but none of that seemed to work and I dont wanna buy a bunch of stuff to replace if its not the issue any feedback is appreciated. Thanks!
