Well it ran really rich with the vacuum line off. That vacuum line was connected to the MAP sensor. When it was disconnected you could smell the fumes a mile away and the idle was extremely high, 2000rpm. Now that it's connected it idles pretty low at under 1000rpm. I don't know why but that's just how it ran and it would only run well with the vacuum line disconnected.

 

That's a bit clearer. I thought you were getting 9 now, after getting 11 with the vac hose disconnected.

Actually, I'm totally confused...........

 

Oh haha sorry for the mix up. As soon as I refill the tank I will calculate the mpg. By the way, would you know why my gas tank never fills up? I have to keep "topping it off" to get it even close to full but usually stops at 3/4 of a tank. I know I have a small tank but it never fills up all the way. It usually only takes 9-10 gallons from empty to 3/4 and the pumps stop pumping for me as if indicating my tank is full.

 

Perhaps the sender in the tank is inaccurate?

How many of my Renix tips have you done so far?

 

Ok I'll look at the tips for that.

I have done 7-8 of the tips. Thanks man they have been extremely helpful, without them
I would have probably sold the truck for a couple hundred or donated it. Thanks again man.

 

Cool. Which ones have you done so far?

 

1, 2, 3, 5, 7, 8, 11, 14.

They have all helped somewhat and I have also replaced the fuel pump, fuel filter, CPS, TPS, air filter, oil filter, oil and a few vacuum hoses.

 

Great!!

Do 4 and 6 when you get a chance. 6 especially.
#25 if and when you replace your valve cover gasket.

 

Thanks I think I need to do the valve cover gasket ASAP. I hear a weird rattle noise if I accelerate from a stop to fast.

 

Hear and/or feel it? Coming from under your feet?

 

Hear it only and it come from the engine

 

Auto or manual trans?

 

Auto

Wow so the jeep is doing the same thing again and when I went to disconnect the vacuum hose to drive to work I found a gas leak. What can I do or where can I get this part it connects directly to the fuel injectors.
