I guess I'm going to try to clean the TB and sea foam the engine. Would I be able to reuse the TB gasket and apply some gasket sealant around it?

I was searching around and found a topic about the oil pressure sender unit.
Is it true that fuel delivery is depended on the oil pressure?

Don't ignore it.

Not 100%.
Oil and fuel pressure are not directly related. There are parameters that if your oil LEVEL sensor reads empty that you should have no fuel. I know for a fact on my 97 that I can run at 3,000 rpms with only 5psi of oil pressure. Which we all know is smoked bearing land.

If you read above, Barry, you'll see he already checked his fuel pressure (which is done after the FPR), although I'd like to see him do it again at idle, and pull the vacuum line off the FPR and record that pressure too.

I did read the above, but my son'* '97 SE was hard starting and had ok fuel pressure. Took it to the shop and they replaced regulator and all was fine. I actually think there was a recall or TSB on the regulators.

The regulator I have now is from a junk yard, I got 2 of them from there, but one of the screens was ruptured I don't know if I put the wrong one in the car. I'm going to look at my FPR. I'm going to have to get in contact with my friend again for that fuel pressure gauge again.
I forgot that another reason why my car is running bad in hot weather could be that I'm low on oil.
It'* below the bottom notch. I was going to seafoam and change the oil + ring seal and spark plugs after I did my heavy duty TB cleaning, but haven't got around to it. :?

I was wrong.. you are killing your motor. Congrats... I hope you take better care of the next one.
