I have a 94' Explorer, 4.0 OHV, and its very tired with either 196k or 296k. Took it on a wheelin trip to my buddy's camp this weekend, on the trail there I developed a low, 500 rpm, and very rough idle, but as soon as I got on the throttle she cleared right up. It got slowly rougher and rougher as the weekend went on. Today I had to get some gas in BFE to make it home, and of course they were out of regular so I was forced to pay $4.69 a gallon for premium. When I went to pull out of the station, I turned the key, it started but died out instantly. Tried again and got it to stay running by revving it to 2k and I high tailed it out of there. I let the rpms drop to slow down for a corner and it instantly died out, went to neutral started again and just kept her to the wood the rest of the 45 minute journey home. Got home, cleaned the MAF sensor and gave it a bottle of seafoam and it ran, but only idles at 5-600, even after fresh gas. However it is idling a lot smoother than it did before when it was that low. The check engine light is on, has been since I got the vehicle, last time I checked the only relevant code was clogged egr. I talked to one of my buddies and he thought it might be the idle air valve but we didn't get a chance to look. So I'm asking for any help or opinions. I'm not the best with engine work/diagnosis. Thanks in advance!
