idle

Just pulled the codes on my foxbody. It’s throwing codes 4 and 8(cylinder misfires?). Also codes 31, 34, 35, 64, 45, and 95. I have deleted the smog pump and equipment. The lower intake and upper is typhoon. It has inconsistent idle, smells VERY rich, dies out on idle sometimes or when in...

Hello, Was hard to get into first gear so had Mike's Transmission in McKinney Texas install a new clutch kit for my 2005 V6 Ford Mustang. He said that he used the MOOG kit. Ever since the kit was installed there is a Rattle or Vibration Noise coming from the transmission while the car is...

Please help! I have a ‘94 V6. Driving yesterday, it started idling at 15 to 1600 RPMs. Had to stand on the brakes hard at traffic lights just to keep it still. Even got to the point where the temperature got extremely high. I know there are other topics on the same thing, but I am so lost with...

Hello, Not entirely sure if this is where I should be posting but, I recently put in the Holley Terminator X Foxbody kit along with a Holley dual sync distributor in my 88' Turbo Foxbody. Everything has been running great so far but the idle. With closed loop, IAC and spark adjustment the...

I got a 93 foxbody that I had a blown lower intake gasket on so I tore it apart and replaced that. After getting it back together I can’t get it to go past idle when starting it. I still got good fuel pressure at 40psi at idle. It’s got a Pro M ECU and wiring harness, been converted to coil on...

I'm tryin to get my car to idle properly. It Is idling at about 95kpa, afr is very rich and Everytime I lower the fuel demand it shuts off. It has large cam in it but I don't know the exact specs. All I know it was a nitrous build with a solid roller with close to a 600 lift.

I have a 86 GT, 5spd. Engine is a 5.0(302) with gt40 heads and intake. e303 cam and shorty headers with catless xpipe. I am running microsquirt from efisource and an aem xseries wideband. Engine starts and runs great up to operating temp. I have an electric fan that's controlled by the ecu and...

Hello, I have a 89' foxbody and I recently took apart the upper manifold and cleaned all ports, put it back together and it idled in the 1,500s without coming down for 30 seconds. I went ahead put a new IAC and TPS, and adjusted the idle down to 800 RPMs. The car didn't run good after any of...

I've been having surging issues for a couple of months now. I replaced my IAC and checked for vacume leaks and tested my TPS. The surge is only slight. Maybe 25-50 rpm when its warm and on a real cold start it surges quite a bit for about a minute before smoothing out. I've done a reset and I've...

I'm new here but I have a 04 GT standard trans and my OEM plastic manifold broke at the heater hose fitting so I replaced it with a professional products typhoon intake manifold and I installed it and now the cars idle is very rough. Bouncing between 1200 rpms and 500 rpms. Thought it could be...

Hi, I have a 2015 salvaged coyote in a 67 mustang running on the control pack. Everything is up and running, but it seems to have a rough idle at start. The idle continues to be rough until I rev the engine and it settles down to normal at around 1000rpm for about 5 seconds, after 5 seconds...

Hello all. This is my first post on this forum. I thank you in advance for the time and consideration you give to my issue. So, I just picked up a 1987 Ford Mustang LX 5.0, hatchback, 5 speed, all original, 100% stock, 27k miles. The thing looks like it was buried in an air tight time...

Hi there, Strange question, I had both motor mounts and tranny mount put in my mustang last week. I noticed right away when I got in the car and started it up that I could feel a crazy vibration in my seat and in the steering wheel that wasn't there before. While accelerating, I notice a large...

My 2010 gt has 45000 miles on her with frpp hot rod cams , frpp injectors , stock manifolds and cats, muffler delete and jlt CAI. It’s a 5 speed manual. Today it was running fine and the cel came on I pooped into oreilly and they scanned it and said both o2 banks were lean condition but it...

(This is copypasta from AllFordMustangs. I promise I'm not a bot, I just posted there first) EDIT: This turned out to be the Idle Air Control Valve. I replaced it, problem solved. I have a 95 3.8, the other day I noticed all of a sudden it was idling high. I had been going down a 35 MPH hill...

150K miles, dual exhaust, cold air intake. Coolant flushed last year but looks muddy already since before I got it it went 5 years on a change. Ok so. This only happens when it’s hot out like it’s starting to get. Whenever I’m at idle (~750 rpm) and the fan kicks on it drops to about 500 and...

Hello guys I need help with my 91 mustang GT, recently replaced the lower & upper intake and had to remove the heads to get 2 broken bolts drilled out . Reassembled and whenever I start the car it jumps straight to redline and stats there .If I disconnect the intake tube it idles around...

Hey everyone, need a more car savy feller to assist me today. Here's my issue: My 03 GT was beginning to stall whenever I slowed down at a light, sign, etc but it idled fine. My first thought was the IAC was going bad. So, after finding one at autozone, I replaced the part and solved the...

Hi! 89 GT with 158,xxx , no modifications. I have been working down the surging idle checklist and so far everything helps a little bit but doesn't solve it. On cold starts it dies unless I rev it up a bit. Codes 11, no vacuum leaks. PCV, IAC, MAF are clean and functional. I separated the ten...
