I was wondering where to check the vacuum pressure at. I can't seem to find it in the book. Does anyone know all the points to check the vacuum pressure? Also what the limits are supposed to be at? If it is in the Hayes manual or chilton manual then can ya give me a page number. I can't seem to find it but know it has to be in there somewhere.

Could my probs listed in my first listing be my EGR valve? I did what it stated in the manual on how to check it and it seemed to do just fine. I also noticed that the manual has a heat shield under the EGR in the picture. Mine does not. Could this be the prob.

After I check the vacuum pressure and it turns out OK I am gong to check my fuel pump pressure. I can't help think that it has to be a fuel problems or maybe the fuel pressure regulator is bad.

I have been doing some driving around and it seems to have problems only AND I DO MEEN ONLY! when it is under load with a real low tank of gas or the engine is at a high temp. This would tell me that if it was a outside temp or engine temp then i would think it to be the AFM air temp sensor. But I don't believe that it is the AFM for the fact that if it was it would do it more often or all the time. It wouldn't have anything to do with a low tank of gas or a load. If it was just under load then I could maybe think it was the fuel pump or something with that system. But with both heat and low gas / load happening its hard to tell.

So I can only guess and think that it is the fuel pump that is the culprit. I come to this conclusion because when it is under load and the gas is low then the pump has to work harder to pump the fuel out of the gas-tank. When it is hot out or the car is very hot, I should say. Then the pump over heats and has to work hard again.

One of the tests I tried was putting cool gas in it:
I drove the car out to the dessert on about 3g of gas. Once it got a tad above normal operating temp then it started its bucking bronco crap so I pulled over. While pulled over I even let it get hotter by revving the engine while it sputtered and grumbled. I also turned on the air conditioning. After I turned off the air and revved a few more times I noticed the clicking behind the glove box again. It died probably 5 times in about 15 minutes during of all of this. Anyway It was pretty hot. I then put in about some gas that I had in a gas can in the back. Right after that I tried to create the same thing by driving around the area and NOTHING. I drove it all the way home without a sputter. STRANGE HUH?

Well, that is my theory anyhooooo..... I will check the fuel pressure and if its bad then I will replace it and hope that solves my problems. If the pressure is good I will probably change the fuel pressure regulator first.... UNLESS ANYONE AS ANY BETTER IDEAs, SUGGESTIONS or OBJECTIONS??????

THANKS

P.S. I am starting to be the Z. hummmmmmmmmmmmmm
