    Looking for some advice.. I installed a 92 Thunderbird 5.0 (same as SN95 stuff to my knowledge) in my 87 Ranger with a T5Z. I had these vacuum lines plugged off for about 4000 miles. I finally got around to hooking them up as pictured, and now the truck likes to die when coming to a stop from...
  2. SVT & DOHC
    I recently picked up a '96 Cobra with a nicely built bottom end, ported heads, Sean Hyland cams, and a Vortech SC. I can tell the car was set up to make very nice power, but at the moment it's got some issues. The first one I am trying to resolve is a crazy surging idle issue. The car will idle...

    Hello all-- Recently went to a TFS setup on my 1994 GT but have this one persisting problem I'd like to get some feedback on before I throw money at the problem in hopes of it going away. Symptoms: Car does not want to stay running on a cold start. She'll turn over and fire just fine but as...

  7. GT & SOHC
    Okay, so I have this problem where when my car dies everytime I start it. It goes a little something like this: *insert key, crank, click click click click click click click click click ***** VROOOOM ****** (to like 1200 RPMS for like 2 seconds), then they go down (0 RPMS) and it just dies...

    I have a IAC motor in excellent condition for sale. Works perfectly fine. I also recently cleaned it out with a rag & carb cleaner. $25 shipped
  9. GT & SOHC
    My 2000 GT has started acting fishy at the first startup of every day. Problem is that it misses, farts and struggles for about 10 seconds after startup. This only happens when it has been sitting overnight, and never if i drove it already that day. Upon startup the RPMs jump to 2 grand like...
  10. 94/95 Tech
    So heres the deal, I had a rough idle and sometimes the car just would not drop in RPMs after inbetween shifts or when i would push in the clutch right away. I have literally replaced everything in the ignition and fuel system on this car hunting down several problems (some not related here.)...
  11. 5.0/5.8 Engine Tech
    So whats going on is some weird issues with bucking/jerking at low RPM, (minor) and more importantly, very little braking power. I'm only measureing 10 HG inches of mercury at idle (850 rpm) and about 15 at 3000rpm. 10 HG seems awfully low and I'm thinking it may be the cause of my problem...
  12. GT & SOHC
    The tune I received from brenspeed set the idle at 800 RPMs. I feel like that is too high and the cams did not sound that great so I put it at 700 RPMs and it sounds really good. I'm just wondering if a lower RPM is hurting the engine in any way. I tried to research this on here before...
  13. General Mustang Tech
    I bought this 93 LX with the idle surging a few weeks ago. Previous owner says he remembered it surging sometime after he put this professional products throttle body on it, and looking at it, I see it doesnt have a hole like the stock one. Car ONLY surges when basically at a dead stop, at a...
  14. Electrical & Wiring
    I think this is an electrical problem, it could be a fuel problem. But its the weirdest thing when i come up to a stop light or stop. The car just jumps between idles rpms, it goes up and down up and down between 500-1500 rpms but eventually it will shut off. but if i hit the gas and rev it up...
  15. 5.0/5.8 Engine Tech
    Ive replaced my air charge temperature sensor, cleaned my throttle body and IAC as well as MAF sensor. the high idle occurs about 5 minutes into driving and is powerfull enough for my car to act as if its in cruise control, when i put my hand over the throttle body while it was running it killed...
  16. SVT & DOHC
    I have a 97 cobra that had a few idle issues. Here is some info on the car. It has 78k miles. I tuned the motor with a SCT xcal2, and have a MAC CAI. The IMRC's were cleaned about 5000 miles ago. Plugs and wires about 10k miles ago. When the a/c compressor was running the idle would hang at...
