Alright guys I'm going to share what's going on and has been for the last week, so my car is an 03 GT SE 6-speed with 146000 miles. Mods are I/H/E - Stage 2 clutch/lightweight flywheel with a short throw shifter.
So okay, I started having problems with the angine while driving to work. It started off at first rough idle then would clear up after a few mins so I figured it was just a hiccup but then it started doing it while driving too (jerking and throttle would kill the engine) It started to happen more and more so I read up on NT and I ruled out it could be the CPS so before it died and completely left me stranded I replaced it, PITA btw due to it breaking off in the block but we got it. Come to find out that it wasn't the CPS and it was the FPR, it took a $hit on me and I was left stranded anyways. SO...I replaced the regulator and it ran rough for a few mins then smoothed out, thought all was good until I drove it later that day on a couple hour drive and when I went to accelerate and pass someone out of nowhere it sounds like the engine starts to misfire like crazy and has no power at all (Limp mode), I can drop it in neutral and rev it up a couple times and it goes away and when I drive normal it never happens but once I accelerate hard again it comes back. I had an autoparts store hook up to and and it's throwing misfire on all 6 cylinders (random misfire) and that's it nothing else is throwing code. So I'm so stumped, I have already ordered the TPS and the IAC in Hope of fixing it but as of now I've already started to chase sensors and I don't know what else to do. It doesn't have the power it used to either like something is choking it down, I cleaned the MAF too so yeah......can anyone try to give me an opinion on what else it could be? I would appreciate it so much and thanks guys.
Also I never unhooked the battery to reset the vehicle after installing the FPR and the CPS, do I need to? I figured the ECU would read after a couple minutes and set it's paramiters back to normal.
