    Looking for an answer to this issue, code reads Evap emission system control valve (low/no flow) and do not know what I need to do to fix this. Also, when ever throttle is given, the car bogs at times, like not enough fuel or something, are these issues related? Also, not sure if this is true or...

    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...

    Hey everyone, I just made a similar post but I thought I'd start one slightly more relevant to the problem. My Autolite 1100 is making a really loud crackling noise at idle. You can hear it even with the air cleaner on. It sounds like someone is sucking up fluid with a straw, but a lot louder...

I fixed the break up issue I talked about before with a new distributor but the car still wont idle. I have an a9l and an sct chip and I'm starting to believe I have a...

    Hey guys, I'm new to the forum. Hopefully I can get some much needed help. These past 3 weeks I have been having issues with my GT. It first started as I was driving down a highway and the RPMs started majorly surging. It started out going from about 2k-4k then gradually went down as I pulled...

    2003. 3.8l v6 5 sp manual. So, my idle is right around 1000 rpm, but it will fluctuate slightly between 1100 and 800 while in neutral without me doing anything, i turn it on and it bounces, i dont mess with a/c or anything. Also at low speeds, generally while braking, it will randomly stall out...

    Hello Mustang Community! Just got my 2009 GT back from the shop with newly installed Hot Rod cams and a fresh BAMA tune. Ever since my Stang has driven terribly and is a chore to drive. The idle is around 800-900 from a start, but when slowing down to a stop, the RPM bounce from 200-1000...

    I am having a problem with my with my idle. When I start my car the idle is around 2000 rmps, after a few minutes the idle will drop to 1500 rmps. Sometimes the rmps will drop to about 800. What could cause this problem?

    Hey guys, It's my first time posting here and hoping to get a little help. I purchased my mustang about 2 weeks ago. It's a VERY cold day and i start my mustang, I then go out to clear snow out of the windshield(took a while). When I come back in my engine starts a VERY loud humming sound...

    Hi everyone, I have been Reading a lot of advice on here for a while but never have had to post. Here is the problem I am having. My mustang runs perfectly right until I shut it off for any given reason. Let’s say I drive it and all is fine but when I go to get gas or go buy something really...

    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...

    I read through several threads here over the last few days trying to fix my idle issue and finally think I got it. I want to pay it back by listing what happened and how it (seems to) have been fixed. I'm not terribly knowledgeable about mustangs, in fact my truck is a 73 toyota FJ40 with a 92...

    My 91 foxbody seems to idle really bad . Last nite I notice when I started it up the rpm and batt gauge where jumping up and down and stalled once Then as I was driving I notice that when I accelerate and let the gas pedal go the car seems to stay on that rpm for a couple seconds. And while on...

    My 06 V6 automatic idles oddly. when I shift into park the RPMs drop to 4-500 and it shakes real quick and almost stalls out, but then goes right back up to the normal 650. I have been told to try cleaning the throttle body and/or MAF sensor and I am wondering if that's what I need to do, and...

    RE: 1994 Mustang 3.8L V6 Auto. Issue: Rough Idle or Miss at idle, stumbles when you first give it gas - Barely noticeable at idle but once put in drive with foot on brake you notice it easily, and gets worse with A/C on. Past: Car has been on the road running like this for 2-3 months...

    I have now resolved my idle issue from my last thread. After replacing the IAC and getting the EGR system deactivated I no longer have a problem with a stumbling and rough idle. I do; however, still have the ticking problem that was also described in my previous thread. I had suspected a...

    Hi, I have been having some timing issues with my 1992 5.0. I am pretty convinced its my ignition control module. The engine will have timing advanced to nearly 35* at idle with the SPOUT plugged in. I will do some more diagnostics before I confirm its the ICM, but I want to start looking at a...
