Wouldn't hurt. Is oil consumption high? That's a sure sign of glazing. Mike is correct, if glazed it'll have to come apart to be fixed right. You could try the old trick of running something mildly abrasive through it but that rarely works.

Prolong idling after rebuild is a good way to prevent ring seating and glaze cylinders. Odd that someone of your dad's experience doesn't know such basic stuff.

Oh that's cold but don't worry Nick, it'll happen to you. Manianac: At least one brand of development system with emulation support for the chip was available back in the 80's. I know because I've used it.

Wipe it off and make sure the pressure sensing holes are clear. And they can be cleaned, but not with common solvents. Not that it should ever be needed.

Uh, you claimed it wouldn't start...

There are several things on the TB that can be adjusted, along with the throttle linkage itself. They should be done in a certain order though.

Are your friend's cars stock? Could be lots of things but without knowing what you've done to the car it's tough to even guess. All I can say is: 1) The AFM isn't used for starting the engine even when it is connected. That alone proves you have a problem. 2) If everything is working...

Oh the humanity. When will the carnage stop?

^ Seems to me having it unplugged kind of puts a crimp in that theory...

It'll matter when the AFM fails and you end up stranded, which is not what Toyota intended when they designed the car.

Not this again...

A small amount of vapor/smoke is normal. After all that's why the PCV system is there and by removing the oil cap you're venting the system. There shouldn't anything like JS is seeing though. As for better diagnostics measuring crankcase and valve cover pressure with a manometer is what's...

You must be a young fella...

Useful when fixing your headlight beam leveling system ;)

25 and 26 are usually caused by the engine not being in fuel control or a faulty O2 sensor. Check what the sensor is doing per the TSRM by using either the OX or Vf terminals. The only way to get 51 from the AC is if it's on (AC button illuminated) or the AC amplifier is bad. Missing or broken...

Corolla doesn't work the same way. Unplugging a 7M valve will simply freeze idle speed at whatever it happens to be at that moment.

He's talking about this: chinozie.googlepages.com/Supra_MA70_Wiring_Manual.pdf

Me too. He's my idel :)

Wants the MEL comes on you should check for codes...

What Poodles said. Even if the smell is coming from something else the fuel system is still the most logical place to begin looking. A rest pressure check might also help but the leak may either not be present during that time or be too small to effect rest pressure. You could also crank up the...
