rough

Car history: New to me (3mos) Garaged most of its life, last owner did not drive very much, overall great condition runs excellent. I just had new points installed, timed, Carb adjusted so it was running perfect. Last two days in gear at stop light or slow speed under 25mph car feels like a...

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...

ok so i have been working on this for a couple of days now and i think i need some help. so i found that when it is idling it runs fine but when i put it in gear it and give it a decent amount of gas(not full throttle) the car slows down but when i give it full throttle it gives it enough gas to...

First off, the engine is a 4.6 3v from a 2005 Mustang GT This engine started with the common symptoms of a VCT/phaser issue. i.e. Ticking noise, and rough idle below 1500 rpms when the car was fully warmed up. I replaced the timing chains, guides, tensioners, and phasers. I also replaced the...

Hey guys, to start off I'm pretty new to this website and pretty inexperienced at wrenching. I feel that I know more than most average people about cars, but don't have that much experience so any help is much appreciated. I have a 95 gt and I recently put bbk long tubes, bbk off road x-pipe...

So when im driving (not all the time but sometimes) usually in 2nd or 3rd gear in the lower rpms the engine will sputter or it will sound choppy you can feel it in the car as well. If i apply greater force to the pedal it will accelerate and will sound normal, if normal pressure on pedal it...

My 2006 GT just hit 70k miles so I decided it would be a good time for a tune up... I did my research here about the plugs breaking and whatnot before attempting to change them. Well even after going slow and using the PB Blaster (2 hour soak), 4 out of the 8 broke. Batting .500 :heha: But I...

When A/C is set to off, car runs perfectly, because when I got the car I had to replace the IAC and cleaned the throttle body. It's a 2000 Mustang GT and runs great when A/C thing is off. When it is set to vent, sometimes it starts to idle rough and goes to like 500 rpms and stoplights and...

I have a decently modified 5.0 with trickflow upper lower intake eldebrock heads b303 cam 24# injectors with maf and first of all she's real cold blooded it will die a few times before being able to idle at a cold start then it idles fine but the main problem is that it bucks and pops like crazy...

Ok so I just installed my 24" radiator to fix my running to hot problem. Now it will run like it's misfiring. Sometimes when I drive it, it will run fine, then again run rough randomly. This didn't happen before I switched out the radiator but I couldn't see how that has anything to do with it...

Hey guys. basically..I'm an idiot and need to ask you guys everything :) I have a 1968 coupe mustang with an edelbrock electric carburetor 4bbl. It is idling rough at stop lights, sometimes to the point of the car dying. If I give the car more gas I am able to smooth it out and keep the car...

Just installed a new carburetor on my 65 mustang 200 cid [running a rebuilt '67 engine]. After it was installed the car started fine and we let it idle for quite awhile making sure the timing and fuel mixtures were good. We took it out for a quick drive the next day, and everything seemed fine...

Hey guys, well, i have a 2001 mustang convertible, and i went to get my car washed yesterday. When i left the car wash, the car started misfiring. I was wondering if someone would happen to have a spark plug diagram for the 2001 v6 mustang. Well, a picture would be better, with microsoft paint...

I think this is the weirdest problem i have ever had....the engine seems to be idling really fast, like the belts are rotating 3 times faster than normal as soon as you crank it....i thought maybe the throttle was stuck open but it wasnt, no gas is being given to it whatsoever(except to keep it...
