Having problems with my '98 Ford Expedition. Won't start, misfiring, very rough idle when I can keep it running. Kind of hard to describe.. I thought it was the fuel pump, so I changed it. Now, I'm thinking it's a vacuum leak.
It's throwing two codes: P0102 & P0113. I know what these mean in theory, but I'm not a good enough mechanic to apply the knowledge.
Are there any wizard mechanics in the house?
I got firearms to trade if someone can get it running like it's suppose to.

With both of those codes dealing with sensors in the intake air, I'd look first to see if the duct from the air cleaner box is cracked or not attached. Is the air filter clean? After checking those things, any auto parts store will have an aerosol can of MAF cleaner. Follow the directions for use. This is worth a shot for a quick & cheap fix.

If this doesn't fix the issue, those parts are relatively cheap and easy for a DIY'er to replace. Rockauto is a great place to get these parts.

Good luck!!

When did it last run normal? I would unplug the maf sensor and see if it starts easier. See if it starts and idles normal for a sec on starting fluid. There might be a Schraeder valve on the fuel lines on the intake to test the fuel pressure. A gauge would be nice, but you can just push the valve down and if it spews out with pressure, fuel likely isn't the issue(let the gas evaporate before messing with it again).

How long has it been since you did a basic tune-up, spark plugs, wires, cap & rotor (if it has those)?

That range of Ford motors also had a lot of trouble with the EGR valve caking up with carbon. Caused lots of strange issues.

My Dad's old 88 chevy would do that. It was the EGR valve. You could take it off and it would run . Wouldn't hurt to pull it and see if it changes.
