I finally decided it is time to repaint my cobra. The car has just over 40k miles but I've always wanted to repaint it due to some sun damage from when I purchased it. I was able to track down a guy who came highly recommended to repaint. Keeping the original Redfire G2 color. To keep costs...

Checked the codes on the car (03 Cobra) just out of curiosity and saw a P0148. No problems that I can tell. What would cause the code but exhibit no symptoms? Car has intake, exhaust, a VMP dyno tune, and a FPDM wire upgrade. All mods are at least 4 years old and I've never seen this code...

A bit of a mashup of parts for sale from the years of accumulating stuff. Shipping is at buyers expense (actual cost). Pictures of everything is here: https://photos.app.goo.gl/2QZ1WLqS8gSA1Kh27 Autometer 3863 fuel pressure gauge (has two pressure fittings but no harness between the fittings...

My last thread was removed and the mods were unresponsive to re-instate it. If the mods have a problem with my thread I ask that you at least respond to my PMs so I do not have to re-create the entire post. All parts are OBO and prefer local pickup. Everything will go to the scrap yard if I...

I've noticed this in my car from time to time but yesterday it happened a lot in one drive. There seems to be a solenoid or a relay thats engaging under the dash on the drivers side, I can hear it click on and off, and whenever it was happening I heard a single ding coming from somewhere. It...

I have a used Magnaflow catted X-Pipe that came off of a 2003 Mustang Cobra. As far as I can tell, it is this x-pipe: http://www.americanmuscle.com/1999-2004-magnaflow-catted-xpipe.html I ran it on my 03 cobra for a few years until I changed to a different x-pipe. When I bought it (used) I...

I had a used magnaflow x pipe on my 2003 cobra for two years and never experienced any backfires. I ran over some metal that dented up the cats so I bought another used magnaflow x pipe from a user on here that looked to be in good shape. I removed the old one and installed the new one and...

I had MM FLSFCs installed two years ago and I'm not sure if it has been ever since then, or it gradually happened, but whenever I jack the drivers side up on the subframe connector, right at the front where it's welded, the drivers side door gets really hard to open. If I jack the car up on the...

I'm listing this here for my dad. I will copy and paste the craigslist text and put up some additional pictures Car is located in Richmond, VA. Price is $650 "Lots of good parts (and a few bad ones) V-6 Jasper engine supposedly has less than 100k. It ran strong & AC blows cold, so sounds...

So I drove my car in to work today and as I'm leaving the house and getting up to speed I go to shift to 5th and the trans grinds. I was a little unsure of what happened so I attempted again and it went into 5th. Since I know the t56 has a reverse lockout I try it again and sure enough it's...

Detailing 03 redfire cobra, did a few test spots with m105/m205 and orange/white pad combinations. Didn't see much difference between m205 and orange, m105 and orange followed with m205 and white, and m105 and orange. Granted, the car is pretty scratch free, but the minor water spots and light...

I broke the metal part of the gas pedal assembly (the metal kind of twisted sideways so my pedal is crooked now). Is this part replaceable by itself? If so, where would I get one? I need the piece that is like this (but obviously for an 03 cobra) Mustang LX GT Cobra 2 3 5 0 Throttle Gas...

Went to MIR for the NMRA Nationals on Friday. Met some cool guys (Zach, Garrett, and someone with a mystichrome cobra, I forget your name dude!) Got my car tuned by Justin on the dyno. Car has JLT cold air intake, mangaflow x pipe, and magnaflow catback. That's it, as far as performance...

I only noticed this somewhat recently (the start of this winter). When the car is cold, it grinds a tiny bit going in to 2nd gear unless I'm really slow with it. As soon as the car has been moving for a minute or so and get's some heat in it, 2nd works fine. I have Amsoil ATF in there right...

I don't have the datalog to post up, but I just wanted to ask a few questions regarding it. When the car was warmed up, I did a 3rd gear pull from 1750 rpm to redline. Here is the overview of the log: Load peaked at 1.65 under full throttle STFTs went to 0.8125, both banks, once full...

I got a tune awhile ago, but never got around to posting about this. The car runs great. I'm just curious more than anything. If I start the car cold, it'll go like normal for a few seconds, and then it sounds like something engages, and the RPMs drop, and sound almost like a hum comes on...

I made it out to the local eighth track for one last time before I clean the car up and put her away. Mods: x pipe, catback, jlt intake, IRS bushings, tune, slicks Best of the night was a 7.77 @ 93.59 mph with a 1.76 60'. That was with leaving around 3k rpm or so. I went one more...

So, this only started happening recently as far as I can tell. And it doesn't seem to happen every time. But I'll start my 03 coupe and shortly after I hear a simple chime, kind of like a seat belt chime. It only dings once and then that's it. Anyone ever encounter this? All of the gauges...

I'm trying to keep water spots off of my cobra. I am considering either getting a water filtration system like the CR spotless water system, or something like the master blaster. I have well water, just FYI. Which would be better at eliminating water spots and better for the car overall? Thanks!

Is there a difference between the rear calipers on a 03/04 cobra and lets say a 99-04 GT or V6? Not talking about the hoses or anything, just the actual caliper itself

So, last week a technician from a satellite company came to work on my apartment's satellite. My landlord was with him on Monday the entire time he was there. However he also came back Tuesday to finish up some work. He was there at 8am when I left for work, and I spoke with him shortly, and...

Well, not completely stock. Magnaflow catted x pipe and catback, ftbr bushings, flsfcs, and mt et streets. No pulley or intake or tune. Best run was a 7.98 @ 90.29 mph with a 1.82 60ft. I was still bogging after launching around 4.5k, no spin or hop at all!! Tires were around 18psi. I know I...

I had to do grinding on three parts to get the 15" wheels to fit (unsure of backspacing) Caliper mount - had to grind both edges down so it's not a 90 degree angle, but more of a sloped surface Caliper edge - had to grind the edge of the caliper down so it's sloped as well Tie rod mount...

Went to the strip last night. First time at this dragstrip with the cobra. I went to a different eighth mile last year and was cutting 1.9 and 2.0 60 fts on street tires completely stock. I think the prep last night sucked compared to that. I cut two 2.24 60fts, terrible. Was getting a little...

Anyone here own or knows who owns a yellow 03 or 04 cobra with the license plate "HIT THAT"? It had black letter inserts on the rear bumper. Was driving south on 95 just north of richmond.
