    Bad PCM?

    You have two grounds to the engine. Should definitely NOT be 10 or 20 ohms! ..should be close to 0. Big ground on passenger side to motor mount stud/bolt; small strap ground behind driver's side head to body at front cowl area. Make sure they are snug and clean.

    Should I stay away from 2005 to 2008 (spark plugs)?

    Don't let old spark plug design issues scare you away! Even if the original two-piece design is in there, they will come out without breaking, if done carefully and slowly. Putting too much reverse-pressure on them while removing is what causes them to break. There's ways to do it. And, worse...

    2006 Mustang GT Manual Convertible FBO Dyno Results

    373's are a reasonable option for both highway and 'fun improvement'. But, if you are wanting optimal MPG (with th bolt-ons, that's probably not the case), sticking with stock gears is your best option. 355's are another alternative, but not as big of a difference. I like and use 373's in my...

    2006 Mustang GT Manual Convertible FBO Dyno Results

    yeah, but that's a slippery slope: once you do, you'll never go back to n/a! Good n/a numbers there, nice t/b, too :) @MustangMark not a bad result, though. You know how different the car feels. Don't get obsessed by the actual numbers, enjoy the car as it is, or as you tweak it. I've been...

    Another differential whine post

    Pinion is usually growling/grinding, whine is usually backlash (differential)..from installation variances.

    Another differential whine post

    Whine from improper backlash is usually related to certain speed ranges. If it's there, always, you have some other bearing/race issue. Could be pinion inner or outer, differential, or wheel bearings. A properly-installed set of gears will be quiet.

    05 Mustang gt driver side axle not going in far enough

    +1, they should be different length axles; they might not be. Got to get them in on the proper side. Hopefully the other axle works out for you. Since you're there and there was some noise and problems on that one side, consider replacing the outer wheel bearings and seals. That might take care...

    SUSPENSION REBUILD

    A few things you don't really need to replace: - upper panhard rod support brace: it's all metal OEM, no rubber bushings, no real need to replace it unless it's bent. - the sway bars can have the links/bushings replaced, but if you want to replace with new, that's up to you. Workmanship-wise...

    Coolant smell

    Add a little coolant leak dye, run it, use a UV light at night to easily find the leak. If there is a serious leak, the coolant level will drop, so keep an eye on that. The alum t-stat housing shouldn't be leaking, but if you reused all the hoses and spring-clamps, it's possible there is a seep...

    6R80 in my 05

    No need to "sell everything", lol. One thing I found helpful was to make sure the proper Torque Converter Type is selected (as shown in the second picture above); I had a different issue, and after speaking with tech support, went in and set the type that was appopriate for my setup. You can...

    Ground Wire, O2 sensor, or Fuel Filter

    Good point there. Check the voltage with engine running (and off), and see. If engine off voltage is over 13 volts, it could be a battery problem. If voltage is over 14.5 volts when running, especially if over 15, the alternator is overcharging/over-voltage and that can cause all kinds of...

    Ground Wire, O2 sensor, or Fuel Filter

    All of those are not going to go "bad" at the same time! A ground or voltage supply issue is more likely. If there was recent work such as removing the transmission or headers installed, there is probably engine harness damage and a subsequent fuse is blown. I would measure voltage at various...

    Bushing removal and installation.

    Same as others, I've used a hole saw drill bit, or even a longer 1/4" drill bit, and drilled around the center bushing to break away the rubber area. Knock out the center with a hammer. Once out, clean out the remaining rubber; a good stiff drill-mounted wire brush bit works good. Once the inner...

    5R55s Replacement Advice

    For a stock V6, stick with the 5r55s. A 4R70 is meant for a v8 block/modular V8, and the bellhousing is different in the 4.0L you have. Not to mention all the other changes to make one work. FWIW for those with a V8, a 6R80 is the more common and preferred upgrade now, espcially if you need to...

    Power Steering question

    Another factor can be the type of fluid. The suggestion to replace the fluid is a good one (empty the reservoir), and fill with mercon v transmission fluid (that's right, mercon V is what the specs call for using). But, it does sound like the pump is on its way out.
