Its 94 Sport(Will). Maybe hes just special.

 

Oh, he's special alright.

 

Ain't that the truth.

 

So no answer?

 

I Have a 90 Jeep cherokee with A 4.0 Straight 6. It idles ruff and will die after a few min. I have replaced the Map, O2, Crank shaft position sensor, Injectors, spark plugs, wires, did a fuel treatment, did a leak down, and checked for vac leaks. I don't know what else to look at. If it helps it started running ruff after driving in the ocean. It was Stupid i know. So anything would help. thanks

Have you cleaned your IAC?

Listen to cruiser. He knows what he's talking about.

 

Ya I have Cleaned the IAC. Would my EGR be bad if its Rusted?

 

Not really. Do the stuff I posted first.

Have you even looked at it?

 

my fuel mileage is awful on my 01 sport after putting on my 31' tires. what can i do to balance it out? i was only getting like 15 or 16 mpg to begin with

 

Did you change the speedo gear so that your odometer reads correctly?

 

No I haven't Looked at it.

 

no but ive tested my speed with a gps and a police speed checker and its still pretty much dead on

 

You need to.

 

Then one of two things has happened. Your odometer read high before leading you to believe you were getting better mileage than you were, or you really do need to change your speedo drive gear because now it reads too low. Define "pretty much" as far as speedo accuracy now.
