Nope you should pull all of the plugs... we have tested by pulling one plug out before... We knew the engine was toast, and just wanted to check a cylinder for **** and giggles.. That motor was ran so hot I think we got 20 psi from one cylinder...

Hmmm thats food for thought... Never really thought about that one Bill

Do you have to push the relief valve to let the psi go JR? undo the gauge w/o letting the pressure go.. it'* only behind that relief valve...just like a FP gauge

Not sure... I haven't paid close attention... And its been a good while seince I used it... I believe he had to push the button to let the pressure out... Not 100% sure... I think I need one for **** and giggles... **** I can't think that far back.. You got me there Billy

Thanks for all the advice throughout this thread, guys. I do appreciate it.

I am going to be giving the car to a needy family from work. The older man (who I worked with) has an 1988 Econoline van that'* dieing on him. He has no money to get it repaird and gas prices are killing them.

He'* been a real inspiration to me. His values are paralleled by none other.

My wife and I need a fifth car in the least way. I can't think of anything more appropriate than to give it to him. IMO, the $300 that I have invested into the car trying to get it running correctly is going to a very, very worthy cause.

If he asks me questions about it that I can't answer, I'll be sure to post the questions for all the experts to help me with!

That is actually very nice....

I don't know what exactly is wrong... But I hope the compression is actually ok... And I think it is...

It could be a crank sensor issue...

If you still have the car how about a small test...

Unplug the MAF while the car is running and see if the engine smooths out... Just a shot in the dark... It will set a code... But once you plug it back in, the light will go out...

Should be the large sensor on top of the throttle body...

Ya, I figured it out after I posted! (Thank god for the Chilton'*)...

Unplugged it and there was no change.

I'm really beginning to think that I've got some excessive internal wearing on the rings/pistons/valves. That'* OK, my friend will get the last amount of life out of it.
