  1. V6 Tech
    Hello all- newly registered and desperately in need of some advice. I drive an 03 3.6L model and the car was very important to a close family member, so I try and take good care of it. Unfortunately I am not much of a car person, and have found myself completely stumped recently. Time came to...

    Hey all, I'm hoping I can find answers or advice on Mustang forums as I have an issue that I've been dealing with on my 03 V6 for a while. For context, in June I hit a pothole the size of a crater. It was either hit the pot hole, or crash into another car. The pot hole impact was so bad that I...

    Yesterday started up my car, stopped for gas on my way to work. After getting gas, it wouldn't start back up. After about 5 minutes, it started again but was having some weird power loss, bucking, and I think it was misfiring, all when I got to around 1500 RPM. I drove it under 1500 for about a...
  4. SVT Cobra Tech
    Hi, SVT lovers! Just joined and I'm thinking that I'm following all the Forum rules, so I'm posting this issue that I have and hoping that I can get your valuable opinions... I got a 2003 Cobra that I bought in 2004 with only 5000 miles on it. The car has been running fine and it now has 67k...

    I have always loved Mustangs ever since I was little. I do not remember a lot about my childhood BUT there is one thing I do remember very well, My Mother had a 1968 Mustang Cobra. I remember sitting in the back seat in a booster seat, as my mom ripped threw roads. Ever since then i have wanted...

    I recently bought a 2003 V6 Mustang. I like the car a lot, but the ride is uncomfortable, so I'm thinking about buying some new shocks/struts to make it more comfortable. What type of shocks or struts should I get? I'd like to be as comfortable as possible when I drive my Mustang. I've heard...

    Hey guys if you could give me some insight on the problem my 2003 v6 mustang automatic is experiencing I would appreciate it. My car has 162,000 miles on it and it recently started bogging down when I rev above 2000 rpm's. The engine feel like it looses power for a split second repeatedly...

    Accidentally banged reverse pretty hard at about 60 mph when trying to skip third and hit 4th, just overshot it a bit. No problem while driving then, but a few hours later I couldn't back out of my spot and had to push it back, though no problems going forward. If I've been driving I can reverse...

    Hello All! Newbie to forum, this is my second mustang. Got a few issues with my 2003 GT and was wondering if they could all be related (seems to be all lights/electrical) or if one or two is separate. Brake Lights not working (all 3, left right center) Backup Lights not Working Turn Signals...

    Hey Y'all! I'm just a girl...a girl who lost her husband but not his 2003 Mustang. I am hoping to sell it in order to get a much more practical car to haul my baby boy around in BUT the check engine soon light came on first and it looks like I'm going to have to learn how to fix it myself...

    My transmission is finally in its death throws of life. All 5 speeds are still operable but reverse is gone. I would like to just purchase a rebuild kit as I don't quite have the coin to get a brand new trans. I don't even know where to begin. Rockauto doesn't seem to carry rebuild kits. I went...
  12. SVT Cobra Tech
    Can I utilize the heat exchanger from an 03-04 cobra in my 96 cobra. I know the radiator will fit with some aftermarket brackets but I would like to somehow use the heat exchanger as an extra layer of cooling since these years like to run warm. Not to mention it would look pretty cool. Is this...

    hi, I have a 2003 mustang gt 5 speed, ive got a few things done to it. I have cold air intake, 70mm throttle body, 75mm plenum, Rally coil on plugs, 4.10 gear ratio, superchips tuner, and I just put on a replacement Dorman intake manifold. My problem is I have raced this other mustang (2001 I...

    I know, my own fault for not checking they were matched before hand, but I guess I just assumed they would be. The current tire sizes are as follows: Driver Front: 275/35/R18 Driver Rear: 285/35/ZR18 Pass Front: 275/35/ZR18 Pass Rear: 285/35/ZR18 So the rear tires are both the same, and I'm...

    I cant seem to find this answer anywhere. But could my intake/exhaust little 2v... somewhat keep up with the mighty g37? I know he will pull hard up top, but at an 1/8th mile track? Could I edge him out? or is it not even worth trying? The G is bone stock to the paper air filter. (its my good...

    I have a 2003 V6 automatic that is making an annoying noise when I turn. I noticed the noise when it was very cold the other day. I looked in the power steering fluid container, and it was a little low so I got some more and topped it off. The noise went away for about 25 minutes then came back...

    I have a 2003 Mach 1 that I'm planning on building to around 600 hp. I know stock it doesn't support that much horse power or torque with the engine or trans. So I was wondering what I would need to do to the engine or auto transmission to make it safely support the power. I'm hoping to keep the...

    Hello I have a 4.6 03 Mustang GT, it's an automatic and I really want to supercharge/turbo it. I have about $2000 to spend and want a kit (not seperate parts to order) that would be a hassle. I found this On 3 Performance - Turbo Kits for Ford Mustangs Any thoughts? What should I do? Any and...
