  1. 4.6L Tech
    Hey everyone! I have been having trouble with my car lately and I've run out of ideas of what it could be. I have a 1996 Mustang GT 5speed and lately it will have its good days and its bad days. Some days i'll take it out and it will drive amazing, like a brand new car and other days it will...
  2. 4.6L Tech
    Hey all, first post here so forgive me if any of these issues have been previously addressed which I'm sure they have, but I just wanted to get the most direct answers possible from other Mustang Fanatics. Anyways, I love my Auto 02 GT but there are definitely a few issues that I'd like to take...

    Bought my 99 4.6 in may and it had a lot of power. Came with 3.90 gears, catted h pipe into a cat back. Also has CAI. July I bought a bama tune and an o/r x for my car but didn't change the donut gasket between headers and mid pipe bc it didn't come with one. One of the bungs was stripped on the...
  4. Superchargers+Turbochargers
    I recently installed a Procharger P1SC Supercharger with the 9 lb pulley and 3 core intercooler on my mildly modified 1993 LX true 5.0. Maybe she's a little more than mildly modified but that's not the issue here. I am new to forced induction so I apologize in advance for lack of knowledge. I...
  5. 2011 - 2014 Mustang GT Tech
    I bought my '11 GT/CS in December of 2010. I wasn't in love with the mustang, but it looked pretty nice and I wanted to reward Ford for their business model. After test driving v6 and the manual GT, I wound up taking the race red GT/CS automatic they had on the lot. fast forward 18 months... I...

    1999 mustang 3.8 No power, hesitating, sputtering and backfiring when accelerating. It has no power, it's hesitating, sputtering, popping and backfiring when accelerating. Runs a little rough at idle, but revs up with only a second's hessitation, until it's under load, then it just bogs right...
  7. 2011 - 2014 V6 Mustang Tech
    When driving my 2011 V6 3.7L Mustang on the interstate, there are many times I want to accelerate slightly (say 5 miles per hour) while making a lane change. I am having the problem that I will slightly depress the accelerator (while at 60 to 65 mph) and get NO response. I press a little more -...

    I have two issues with my Mustang right now. 1). When I apply the gas - from a dead stop - it hesitates as if it's going to stahl before it moves forward. It has stalled once and almost stahled a second time when accelerating from a dead stop. 2). It's really sluggish...even for a 6 cylinder...
  12. 4.6L Tech
    I recently degreased my engine and am thinking I got something wet that shouldn't have when I rinsed it off (I know, that was dumb). It now runs a little rough at up to about 2500 rpm and is sluggish. Idle sounds ok. It has been 2 days now and has not improved. Also, when I rev the engine I...
