  1. 2005 mustang high/surging idle while moving.

    2005-2010 V6 Mustang Tech
    First. I know there are many threads regarding this topic. Unfortunately they are all either resolved by "clean the throttle body" or are simply unresolved. Squeaky clean throttle body here, so hear me out. The car is an unmodified, 2005 v6 manual mustang, with only a few of components...
  2. High tps voltage at idle

    5.0L Tech
    My new to me 1990 5.0 LX 5 speed is having a few issues, mostly with idling. I dumped the codes, and got several. As I work through the problems, I've got code 23: TPS out of range. When I check / try to set the voltage, I'm getting 4.92 volts at idle (ignition on, engine off). The tps that came...
  3. Will TPS do this ??

    5.0L Tech
    Ok, I have been chasing the dreadful idle demon that shows up on my 89' 5.0 from time to time. I have read and google about every article thats out there.. I changed my IAC, with hardly any change. I cleaned MAF , reset the base idle , adjusted idle screw at the throttle. My problem is when I...
  4. Strange Idle Stall Issue Fixed.

    5.0L Tech
    I read through several threads here over the last few days trying to fix my idle issue and finally think I got it. I want to pay it back by listing what happened and how it (seems to) have been fixed. I'm not terribly knowledgeable about mustangs, in fact my truck is a 73 toyota FJ40 with a 92...

    Hey guys.. I have a 2010 ford mustang GT 3 valves. I changed the throttle body for an aftermarket one but they never measured the tps.. Now i have the following problem.. The throttle body does not open, it stays kind of stuck. I went online and it says the tps voltage is from 1.19 to 1.30, i...
  8. Possible bad PCM?

    V6 Tech
    My car (1994 mustang 3.8l) has a rough idle and no power until about ~2200 rpm. I already cleaned the MAF and IAT, replaced the fuel filter (whoever owned the car previously had the fuel filter on backwards), checked the spark plugs and plug wires, and cleaned the throttle body. I was viewing...

    Hi, I have a 1993 Ford Mustang GT 5.0L. After I cleaned the throttle body with throttle body cleaner, the idle started running 1000-2000 RPMS up and down. After this started happening I did a tune up changing the spark plugs, wires, distributor cap, and the rotor. Also I changed the idle air...

    5.0L Tech
    I am in the beginning stages of my first project car, a 1989 Mustang GT Convertible. I have had a lot of fun times so far. This is not one of those times. My mechanical ability at this point is somewhat limited, so excuse me if I contradict myself or otherwise talk out my butt. :winks I have...
  13. Idle problems - replaced and tuned TPS

    5.0L Tech
    The weather in my neck of the woods is going to be about a perfect 72° this week, so of course the convertible is acting up. Forgive me if this sounds painfully familiar, but "the car surges and tries to die at the idle position when slowing down or stopped." Admittedly, I am a TERRIBLE...

    V6 Tech
    I just had my check engine light come on and read it as p0122. I went to replace the Throttle Position Sensor and realized the wire was cut about an inch below the plug. Can I just repair the wires and hows best? Or can i order and replace the wire? I searched and couldn't find anywhere. Is the...

  18. 2008 Mustang TPS, Wrench Light in Snow only

    2005-2010 Mustang Talk
    Hi all, I've done some searching but haven't found any other solution other than replacing the TPS -- which I've already done with a Ford replacement. My wrench light keeps coming on only when its snowing! I don't get it. It happens even when snow begins to fall, not necessarily even snow on...
  19. 2006 V6 fast idle then normal, TPS problem?

    2005-2010 V6 Mustang Tech
    Hi everybody! New to the site and need advice. I cleaned the throttle body and MAF today as well as replace spark plugs (Bosch 4012's). The car runs perfectly except that it holds high idle at about 15-1600 rpms then drops down to normal after 25 - 30 seconds, it does this every time you rev it...
