    The HG thang

    Too much mechanic-ing and not enough basic engineering. Many (if not most) materials when kept within the elastic region have no fatigue limit. Not all though. Aluminum is one that comes to mind.

    just a quick question concerning pricing things..

    Your two cents are worth a lot. I've lost track of how many times I've shaken my head in amazement at youngsters pouring what little disposable income they have into an old car at a time in their lives when it's the very last thing they should be doing. It's financial stupidity on an enormous...

    Assuming it is stalled he could try bumping it backwards. A long shot but it sometimes works.

    87 7M shooting fire. Please help

    1) It's inside the distributor. 2) Put the exhaust back on first, then repair the problem. Start by checking mixture using Ox and Vf. 3) Throw out the Haynes and buy a TRSM.

    ^ That part about the head bolts is nonsense.

    Injectors leaking! Brand new seals!

    ^ Even though that comment makes no sense to me did you install them per the manual?

    what controls engine idle with a/c on?

    A bit late but idle is ECU controlled. In the case of AC the AC amplifier inputs a signal to the engine ECU that causes timing to advance and therefore idle to increase.

    Got offered $4500 take it in run ?

    Based on the number of threads about problems you have (not to mention how much time you spend here) I'd unload that thing in a heartbeat if. Course, that makes you the dreaded PO but you wouldn't be the first.

    Upgrading Factory Alarm

    That'll work or you can connect each sensor to a different trigger and forget the diodes. The 504M appears to be dual stage which is something the stock alarm doesn't support. If you want the warn-away function it'll have to wired separately into the horn or integration relay. If I were you I'd...

    Oil Pressure Gauge Question

    Any mechanical gage setup worthy of the name will have a safety orifice. That said I was being sarcastic about mech gages. They're old tech that are far less reliable and accurate than a decent electric. And the stock gage can be made to be accurate assuming it already isn't. Its downfall is...

    dash light wont turn on when headlights come on PLEASE HELP!!

    I r corn-fuzed. If you can read the EWD the problem should be simple to resolve. No meter?

    Oil Pressure Gauge Question

    ^ Yea...simplicity, accuracy, and reliability are why mechanical instruments are still used in airliner cockpits. OP: The gage can be tested per the TSRM...

    Upgrading Factory Alarm

    Any brand device that supplies ground when active will work. Connect them to the most convenient stock trigger input. They should come with everything needed although you may have to supply power and ground to some depending on what they do. The printed 87 EWD had the pin numbers wrong...

    Upgrading Factory Alarm

    My stock alarm, which worked flawlessly for over 20 years, had the following modifications: 1) Glass/shock/tilt. 2) Proximity (for when the targa was off) 3) Fuel pump disable (instead of starter). None of it is difficult using the EWD. Toyota screwed up the 87 one though.

    7M "Ventilation Hose"

    My thought, other than you need to use the space bar more often, is that metered air matters.

    picked up a dirt cheap supra

    Well, there's a coolant passage through the manifold for the ISCV. Might want to check that.
