Search Results for ‘rough idle’

Put some good fuel cleaner in - ATS - and after a couple of weeks my check engine light came on, 401 code - have tried replacing the two sensors / valves suggested as likely culprits (mechanics out here in San Diego are booked up for weeks) - car runs much better, but still slightly rough idle...

Hey everybody I’ve had issues in the past with my 2012 3.7 v6 with a p0430 code and rough idle I could never get to go away even after changing 02 sensors. After market cats. Plugs, and a few other things I tried. Anyway the motor went it jumped the timing really bad about two months ago with...

I was on a short drive and after I proceeded forward when the light turned green, my car was very choppy as I let the clutch engage, then my check engine light came on, then it started flashing. I immediately pulled to the side of the road. When it was idling, it was very rough. The needle on...

So, Kind of a weird thread to start but I'm at a loss. I have a 2002 mustang gt. when I start the car, its fine, runs great. after it gets to operating temp it starts running really rough and is like it wants to stall. I am only able to get P1233 code, and I've changed the fuel pump driver...

So I recently got this manual 1995 GT with only 44k original miles, the car is great overall. BUT, I couldn't help but notice it has a rough idle (the engine shakes considerably but nothing too crazy) and can't maintain stable RPM's at idle (altough you can barely notice the difference, the...

This has been a week long process so bare with me... First contact: So I'm driving to work (Fort Bragg) and my commute is about 40 minutes. My CEL light is on, but that is normal because i need a tune to remove rear O2s. My car started up fine, was fine on the highway, got to a red light and...

A little over a week ago bought a 2003 Automatic GT. A few days ago I started to notice some issues that might or might not be so common - I'm new to this, after all. I'm going to list them and would appreciate any advice on where to start... thank you to anyone in advance that provides help...

I'm having an issue that started about 3 weeks ago. The car started to idle rough and occasionally surge at a stop, it would drop below 500 rpm then shoot up to around 1200-1400 rpm but if I gave it a little throttle it would clear up. Also occasionally from a stop it would have low power and...

I have a 2002 Mustang GT and it is making an extremely loud high pitched noise noise near the intake manifold. I am throwing the following codes P1506, P0171, P0174, P0316, P0307, and sometimes P0303 and P0300 comes and goes. I thought it was the IAC valve so I replaced it but nothing. Then I...

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...

My 1999 Mustang GT had been idling rough, but when I turned the A/C on the idle would be smooth. So I figured I will clean the IAC and I might as well clean the throttle body at the same time. Went out, bought some throttle body cleaner and did the easy job after watching a couple of...

So I have scoured the interwebs and I have changed a crap ton of parts (ICM,TPS,IAC,EGR valve,PCV,Fuel pump,thermostat,O2 sensor, coolant temp sensor) All of which has made the car run better, but, the original problem still exists. This is a '93 2.3L LX. The Problem: The Car always has a...

Hey guys, I have an 01 gt. I changed the fuel filter for a standard motorcraft one(also used a fuel system cleaner) and suddenly my car has started to waste gas like crazy. I haven't tested the mpg yet but I don't think taking a 30 minute drive on a highway should waste almost a quarter tank...

I have a 1973 mustang mach 1 with the 302 (originally a 2 barrel) now a edelbrock 4 Barrel. It ran perfectly when I bought it straight out of storage a couple months ago, recently it began to act up when I would drive it in the city, it would heat up to around 200 at stoplights and upon...

I have an '87 5.0 with f-cam and gt40p heads, gt40 intake. Just finished it up last weekend. It runs like a champ while accelerating but at holding a steady speed or very light acceleration it jerks and misfires... I har replaced all vacuum lines and have no leaks, new plugs and wires, timing is...

UPDATE 6-25-2014: I was having no luck with BAMA. They tried 7 times and it seems now they won't reply to my emails with questions. Things don't seem right at BAMA anymore, their customer service has been terrible and the tunes have been worse. I fixed this issue with my idle by switching to...

Hello, I am new to the forums. I have a 1997 Mustang 3.8l v6 automatic. I have owned the car since last October. A few months ago the car began to hesitate upon acceleration. The issue is intermittent, usually when colder outside, as the engine warms the problem gets better. However even with a...

Hi everyone, im a newbie to the threads here. I have a 2001 mustang 3.8 auto. I recently pulled the motor and trans due to the fact my wife blew the motor and put the wrong atf into the transmission. The motor that was replace was internally balance and the replacement one was externally...

I just recently got a 97 V6 3.8L Mustang with around 75k miles. It had been sitting with absolutely no use for the past 3 years. I had the fuel pump and spark plug wires replaced. The car does not overheat. It drives almost normal while the engine is still cold. The problem is once the...
