1994 ford explorer 4x4 , i think 3.0L engine, about 170k miles. Situation- Driving car is all fine and dandy, but sometimes it gurgles and shakes a little bit when I first get it started, and after I drive it a decently long distance, it sometimes dies out and has a really tough time starting again. I would let it cool, and can start it and drive. It kind of seems like the engine might be getting choked out? the intake is fine, so is the battery and alternator, no power problems. The plugs seem ok but I haven't checked them in a while but I was told that it might be the cat now funtioning properly and choking the exhaust. what would be the probable assumption in this case?

There isn't one. There is no data or test results in your post to even clue us in to what the culprit may be. If I told you that so and so part was bad, that would be like a jury sending someone to the electric chair without any evidence.

You need to run some tests:

A start would be monitoring the fuel pressure while the problem is occurring to see if it drops out. You need a fuel pressure gauge for that. Another is checking for trouble codes that may be stored in the ECM. You need an EEC IV code reader for that. Clogging cats usually don't make the engine not start until it has cooled down.





Since we volunteer our time and knowledge, we ask for you to please follow up when a problem is resolved.

Roger that. The fuel pressure with the engine running is 30-40 psi

so, i did a computer check with an eeciv code reader and it just came back that there was major carbon build up in the engine. I was told by my local car shop that they used to have a machine to clean that right up, but to just put in fuel injector cleaner for at least 2 refills of my tank and that would clear it up. so far I put in the highest octane fuel there is, along with the injector cleaner, and got to about a quarter tank of gas. It is running better, but now i have more issues. not the truck running, but now the tires. I had bad front end alignment, and a lot of noise from the tie rods so I took a look, and the joints were no longer holding grease, so I changed them out. I did the alignment myself, my truck doesn't pull to any side at all, but my tires are being worn out at an absurd rate. Also it seems like when I turn my wheel, the tires go kind of on a tilt instead of staying flat. I don't know if that is normal for trucks, but I was just curious. My rationalization is that the tire tilts to help the car change direction, but to me that seems like a problem. I wouldn't know exactly where to start in fixing it

There is no such code or information coming out of that computer. What was the exact code number?

That's an absurd thing to even attempt and it's no surprise that the tires are just peeling off. You need to have the vehicle aligned at an alignment shop and ASAP.
