Low MPG

[DandysRanger]

Well it may be a moot point. I was taking it to the store when I noticed I had zero oil pressure. It was running fine and not making any noise so I babied it home. I had replaced the sender a few weeks ago so I am pretty sure that is not the problem.
After doing some research I am going to check the mech pressure first and if that does not pan out then I will pull the engine and start with the cheap stuff. This engine has 200K plus miles on it so it may just be due for a refresh.

I bought a water temp sending unit brand new put it in and NOTHING! Took it back got another and met with SUCCESS!

More than likely it's the sender, if it had no oil pressure you would be hearing some bad sounds.

I hope you guys are right and it is the sender. I replaced it a few weeks ago when I replaced the intake and a couple of sensors. I can't recall ever looking at it to make sure it was working.
I'll try that first.

Woo Hoo!!
Put a mechanical gauge on it and it shot right up to 60 PSI!
One less thing to worry about.

Hey what kind of mileage should I be expecting on my 85 Ranger? I have the 2.3 FI, 5 sp, 2wd, long bed with stock tires / no lift and am only getting 22 combined. This is a high mileage engine that starts and runs pretty good. I've already changed out most of the sensors. I guess the next thing is to replace the cat and oxygen sensor.
Is 22 mpg good for this combo or should I be able to do better?

CEL came on and a code check showed bad DPFE sensor but then I noticed my gas milage went up so I decided to let the computer continue to run open loop for awile. You wouldn't believe the gas milage if I told you.

and how did you switch it between open and closed loop?
