    Build Thread 1978 Fairmont. I bet somebody back home’s thinkin’…I wonder why he don’t write..?

    I do very little hardware repair, it is mostly software. The government agency I work for has specialized software to do the medical part and it isn't like any other software you have ever seen before. Every 18 months half of what I know is obsolete, which means that I have new things to learn...

    Build Thread 1978 Fairmont. I bet somebody back home’s thinkin’…I wonder why he don’t write..?

    My wife's ex was like that; she tells me that he once got a paycheck made out to Doofus (inset last name here). As a result, she expects me to be the same way he was, and there is a continuing stream of doubt and anger directed towards me when something doesn't work the way she expects it to...

    '88 GT Convertible - Croatia, Europe

    @snovak The A/C clutch is about $100 new or you can buy a compressor from the junkyard with a working clutch for about $50. The puller is about $16 if you have to buy one, Autozone will rent you one for free. The clutch hub is usually what fails, the rubber shock damper shears off from the...

    HIGH RPM WHILE SHIFTING

    @PonyGTrider What is the minimum mechanically adjusted RPM you can get with the IAC & SPOUT disconnected? The 65 MM throttle body passes more air at idle than the stock 60 MM throttle body; that is an unavoidable consequence, Some throttle bodies have a hole with a rubber plug in them. The...

    HIGH RPM WHILE SHIFTING

    Changing the mechanical adjustment changes the TPS, so you will need to set it. Anything between.6 and 1.0 volt is good. There is no advantage to setting it to .99; that is a BOZO Internet myth, complete with red nose and big floppy shoes. The instructions I posted said to set the base RPM at...

    Electrical Iac has no effect

    OBD1 does not have the same capabilities as OBD2 - there is no bidirectional data transport built into OBD1 code reader port. If there is a Motes Quarterhorse accessory board plugged into the J3 data port and using software on you laptop or desktop computer you can read and write to the EEC-IV...

    HIGH RPM WHILE SHIFTING

    The mechanical adjustment of the idle set screw is supposed to set the low RPM minimum limit. A properly working IAC is supposed to add air to that minimum limit to bring the idle up to the 650-750 range. This may work out to be trial and error method to get the results you want. Therefore...

    What stud to use on main cap with Moroso girdle and oil pick up.

    If you are using a stock block, the only thing that a crankshaft girdle will do is to empty your wallet. Stock 5.0 blocks split down the middle of the lifter valley because of the thin wall construction of the crankshaft webs . The extra reinforcement needs to be in the block webs and lifter...

    FE Build 1989 5.0 won't start when hot except when using starting fluid

    You may not have a code 14 but still have a PIP sensor problem. The information here on Stangnet points to a deteriorating quality of PIP sensors and TFI modules. It is not uncommon to get several new DOA or marginal electronic parts right out of the box. Code 14 - Ignition pickup (PIP) was...

    HIGH RPM WHILE SHIFTING

    Normal idle speed is 650-750 RPM; 850-900 RPM is way too high for normal operation. IAC troubleshooting Revised 24-Dec-2020 to clean up text and add SPOUT connector and Jumper picture. IAC doesn't work: look for +12 volts at the IAC red wire. Then check for continuity between the white/lt...

    Electrical Iac has no effect

    I don't know where you found the idle reset procedure, but there are 2 omissions: (1.) The base mechanical idle must be set at 600 RPM + or - 25 RPM. (2.) The SPOUT jumper must be removed to lock out the ignition advance. If the ignition advance is not disabled, the computer will advance the...

    Drivetrain Throwout bearing air gap

    With a stock cable there is no air gap; the throwout bearing is designed to be in constant contact with the clutch fingers.. There shouldn't be any difference with a hydraulic actuated clutch. You didn't change the clutch type, just the means to actuate it. If there is an air gap, the throwout...
