    Not a good place to shop.

    lumpy idle

    That is backwards, but you probably just typed it that way. 51 will go away when the throttle is set as already described in the thread. 31 should be checked with your multimeter set to Hz and reading the signal when running bad and running good. Then make sure the PCM is getting that signal if...

    ignition problem, won't start or runs rough

    Something about? The CPS is cam position sensor. The PCM is not getting the signal. This is why when you wiggled the wires it started. They (wiring) need to be replaced.

    Bore Size for Composite HG?

    You can ruin a stock headgasket or MHG by installing a headgasket on a block that is not flat.

    Does coolant run through the IAC?

    Would you like some pie?

    White smoke comes and goes

    Yes, your only deviation should be the torque value. Do what ARP says and do not deviate. http://www.cygnusx1.net/Supra/Library/TSRM/MK3/manual.aspx?Section=EM&P=32

    Coilovers or Shock/Springs??....keep in mind, I'm broke.

    A "coilover" is a shock or strut with the coil spring mounted on a spring perch attached to the damper itself. Hence the name, coil over shock. It has nothing to do with aftermarket or adjustability. FYI.

    White smoke comes and goes

    Assuming you know what cooked coolant smells like, there is only two ways to get coolant in the combustion chamber. One, the chamber is compromised. Two, coolant into the intake manifold. There are coolant lines on the throttle body that keep the incoming charge temps constant.

    Valve stuck open?

    Marvel mystery oil and seafoam? I will be awaiting your next threads.

    Valve stuck open?

    Hmmm. No replies. A leak down test will tell you where the failure is.

    Oil pan question

    Crushing a harness when putting things back together. Since you are looking for ideas.... And if there is no code, it will constantly flash with TE1 and E1 jumped.

    I have a transmission delema.

    At least he didn't spell it with an "n". IPT sells upgrades for all the A340 family members. They can not be that different.

    5MGTE fuel injector non-pulse issue

    In your thread title, you said the injectors are not pulsing. And I was thinking about other things beside your car. My bad. The computer grounds the injectors in group series of the firing order. Battery power is constant to the injectors with the key in the on or crank position with the...

    5MGTE fuel injector non-pulse issue

    Your injectors are in fact pulsing.

    mk3 1jz supra high boost signal at idle

    Because you are using a different engine and harness, then I can't really comment about the 1JZ (ha ha) part. The sensor (common 3 wire) varies the resistance between the gauge and ground. In order for that to happen, you do not have resistance. Said another way, you have 12 volts at the signal...

    lots of upgrades, now wont start. Help?

    Is it supposed to do that? The airflow meter is not used to start the engine, the STA signal is. That also retards the ignition for the low cranking rpm. No. But you could have a large intake leak you do not know about. And that is what an intake leak acts like, as does the engine out of...

    Head Oil feed restrictor?

    This seems wrong. More like oil starvation from lack of replenishment. Or the wrong grade of oil. Something like a 40 or 50 grade that just doesn't flow good unless it is 300 degrees.

    Pushing coolant out and no other signs of BHG

    Assuming you made no assumptions, this is correct logic. Good job. Of course, you already posted your block test, I just wanted to show you did it right, unlike many others here. No matter how bad you don't want it to be true.

    fresh rebuild car wont start

    Are you typing with a baseball mitt? A rebuilt/new engine needs to crank fast for a bit to build cylinder pressure and start. If you have compression leaking out the side of the head somewhere, it probably isn't going to start.
