  1. Cold lean condition/misfire

    2005-2010 Mustang GT Tech
    On cold starts, my car misfires while accelerating. I have a wideband that I know is accurate, so I know it is leaning out. Knowns: Directly related to heat Symptoms dissappear after car heats up Symptoms are less severe/last less time when the car has been sitting outside in the sun all day...
  2. A/C questions

    5.0L Tech
    Hello all, I purchased a '90 Fox about a month ago, the A/C does not blow cold. The clutch will spin for a few seconds and stop. I'm not entirely sure where to go from there, and i believe the car has r-12 refrigerant. If anyone can shed light on my predicament it'd be greatly appreciated!
  3. Goodyear Eagle F1 Tires and cold weather

    Wheels and Tires
    Finally bit the bullet and purchased a base 2012 GT500. The car has the Goodyear F1 tires on it. I read that they were iffy in cold weather. I drove it home from Delaware to pa, about 80 miles, and was very surprised that they did not warm up much. temp was in the low 30's. Traction was not...
  4. 1995 Mustang V6 Manual Transmission Issues! Startup, Idle?

    V6 Tech
    I have had my car for about 2 1/2 years. We bought with problems which were fixed before it was ever taken on the road and it has been running fine except for this one issue. When I would go to start my car (this issue happening only when it's cold) the RPMs would drop below 1000 and it would...
  5. knocking sound in transmission

    2005-2010 V6 Mustang Tech

  6. Cold Air Intakes - Differences between brands?

    2011 - 2014 Mustang GT Tech
    Hey guys I was just wondering if there really is a 'difference' between brands of cold air intakes. Steeda claims to have the highest performance boost between all the intakes I saw, but JLT is the cheapest and people say it is identical. Any input would be great.
  7. 2012 Mustang GT - "Clunky" Manual Transmission

    5.0L Tech
    Lately I've noticed that if I haven't driven my car in a couple days, the first couple of shifts I make are very hard. While the engine is still cold, as I shift from 1st to 2nd gear, the clutch feels like it is engaging/disengaging in a very "clunky" manner. I made sure to press the pedal all...
  8. Having trouble with my heater

    V6 Tech
    Hey all! So I have been running without heat since last fall (which made for an AWFUL winter!!). I have tried a few things, and so far not much luck. I flushed the radiator, but since it was winter, and bitter cold out, I was not able to run the hose through it to get all the junk out.. This...
  9. 2007 V6 4.0L Mustang - Serp Belt Chirp/Squeak (Only when cold)

    2005-2010 V6 Mustang Tech
    Hello everyone, This sort of ties in with my original post which was resolved link. The root cause of that issue was the starter, but during the troubleshooting process, the dealership decided to replace my Serpentine Belt which is now a problem... It's been about 4-5 months since the belt...
  10. JLT Cold Air Intake Rasping at High RPMs

    2011 - 2014 V6 Mustang Tech
    Installed a JLT Cold Air Intake on my 2013 a few months ago and ever since then I have noticed that above about 5,800 RPMs it gets very raspy. I have Flowmaster Axle-Backs so it's much more noticeable. I was wondering if it could be caused by running too lean because of the intake. Just...
  11. 2010+ Cold Air Intake on 05-09

    2005-2010 Mustang Talk
    Has anybody ever tried to fit the 2010 factory cold air intake onto an 05-09 GT? I don't know if it would fit. I like the factory look but I want the 15 or so horsepower upgrade.
  12. service engine soon light is on

    V6 Tech
    Okay, so i just installed a new cold air intake on my 03 v6 and everything seems like its working fine except my check engine light is on. does it need like a new tune or something because of the new amount of cold air going to the engine? the car isn't making any weird noises or anything like...
  13. 1990 5.0 hard to start when cold

    5.0L Tech
    Hey all, I just got back from scanning the OBD1 and I got no codes from it and I'm confused. The car is incredibly hard to start each morning. I don't know really if it's the fact that when I go to start it in the morning, it has been sitting for 12+ hours, or if it's the cold weather (this time...

  15. Do you loose torque When it's cold?

    4.6L Tech
    It's starting to get cold in Socal (50ish degrees :shiny:) and i've noticed my 01GT isn't pulling as hard as it normally does.. Could it be because of the temperature?
  16. Is a Cold Air Intake really of any use?

    4.6L Talk
    I have seen equal arguments supporting both sides, many if them. I can't seem to be pursuaded towards any side. If they really do add a horsepower boost about how many would it add? Doesn't it provide a mpg increase as well? Thanks. I have a 2000 mustang gf.

    V6 Tech
    Ok, so i started using my a/c more recently due to the heat, and realized that the air is blowing decently hard, but its not cold whatsoever, more of a room temp, which in the heat, sucks :confused: Also, i dont know if this is related at all, but my driver size and passenger side front carpets...
