I bought a 94 a couple months and have had a very persistent engine surge that I can’t get rid of. The car (usually) runs fine for about ten minutes of driving before it starts to act up. It suddenly acts like I’ve just slammed on the gas, RPM’s shoot up for a few seconds and then drop back...

Okay, so I have an 04 GT with the basic mods (CAI, TB, plenum, X-pipe w/ high flow cats, MAC catback, and 3.73's) I've noticed this for a while, but haven't really cared much to try to find a solution. No better time than the present, right? Basically, when the engine is still cold and I try to...

Hey guys, I just recently resolved some carb issues thanks to your help. My new problem is that the car seems to idle high. Everywhere I read, they say the 1965 200ci mustang with auto tranny should idle at 500-550 rpm in gear once it's warm. As I adjusted the idle down, anything before 600...

I have an '09 v6 automatic with 75k that makes a vibrating/buzzing sound just over 1500 rpms, right about 1600 RPMs. It makes the noise during acceleration and when driving at a speed in that rpm range (for example when driving at 35mph). If i accelerate through that rpm quickly it doesn't seem...

Curious what RPM is normal at cruising flat highway speed (65-70mph) for a stock 2009 v6 automatic. I think the stock gear ratio is 3.31 (thought i saw that somewhere). The reason i ask is because i feel like mine runs a little high (~2100 rpm) but maybe im just being paranoid

Hello Mustang Community, After having the Hot Rod cams installed in my 09 GT, drivability has been pretty challenging, all in the low RPM's. I have pretty much learned how to drive it the way it is, but there have been some things that are just not right. When decelerating, when I push in the...

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...

My RPM gauge works about 20% of the time. Most of the time it stays at 0 RPM until I give it gas too somewhere about 2k, then it will move a little bit, but still not nearly on track. I doubt if this is a problem with the stepper motors, as it still works sortof.

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 noticed on my old V6 and now my GT that when you hit redline, it doesn't bounce off the limiter, it just stays at 6,200rpm. I'm guessing this is stock. The only reason I'm wondering this is because I keep hearing guys go WOT and smashing off of the limiter and it sounds so good. I'm assuming...

hey guys and girls of all ford mustangs! I have a few small problems that are going on with my 2000 V6. So let me give you a little backstory before I get to my current problems. So a few weeks ago I was noticing that my starter was struggling to turn the flywheel and start the car. I would...

HELP PLEASE.... Bought my first 93 fox body 5 speed 5.0 couple months back. It's pretty strong and reliable but last week I must have gotten on it a little to hard while drifting through a local rod spot. Now I've got a loud almost violent vibration once I get about 1500rpm. Let me start...

My 1999 SVT convertible has the issue that many 4.6 cars apparently have, which is that it holds rpm's too long between shifts or in neutral. There is an easy fix where you put a drilled copper pipe cap into the IAC feed which restricts the idle flow, but I can't seem to find the feed on my...

Hey guys, I just got my 5.0 running again but it idles at a very high and loud (open headers still) 4000 rpms. I've started it 4 or 5 times for anywhere from 5 to 25 seconds each and no change at all. I figured it was just the computer adjusting, but it's not adjusting so far. Any thoughts...

I drive my mustang on a daily basis, and usually when I press the gas somewhat towards the metal, my automatic car usually shifts down and I get the boost of acceleration I always get, but lately it seems to be hesitant on the acceleration even when I press the gas all the way down, it doesn't...

Yesterday, while parking my 1965 Mustang Convertible in the dark, I noticed something interesting. When the engine was idling, all lights (headlights, instrument lights, courtesy lights) had a very low glow intensity. But when I increased the engine's rpm, the light's intensity also increased...

I have a 2013 V6 Mustang with a JLT Cold Air Intake that I installed a few months back. Ever since then I have noticed (with Flowmaster Axle-Backs) that at above 6,000 RPMs it gets very raspy. I have always wondered if it's running too lean up high in the powerband. Has anyone has similar...

My cars RPM's seem to bog down as if I was in a lower gear then they spring back up after I accelerate over 45 mph and then slow down. I've been told it could be the fuel pump, or air intake, or maybe the transmission but I really don't know how to find out on my own. Does anyone have a tip or...
