I have an 88 B2 with the 2.9. Occasionally it will die if I'm turning the wheel sharply with my foot off the gas. Like, going into a parking space. If I leave it to idle, as in a drive-thru or warming up for a few minutes in the morning, it'll rev up a little, down a little, up a little, down a little. It'll go on like that for a while. And then die. Sometimes, it'll just die when I take my foot off the gas.
But, it always starts and when given throttle, it runs just fine. I'm just getting really frustrated with having to start it all the time. We just 'serviced' the catalytic converter and I cleaned the air filter. So, it shouldn't have problems breathing. Any ideas what might be causing problems?

I'm not a mechanic but I'm thinking fuel pressure. Maybe when you turn into a parking spot your stirring up the fuel and sediment/rust causing fuel pressure to drop. The idle could also be caused by this (I guess). Say you have a weak fuel pump , trash in the tank and clogged fuel filters ,... I assume it would cause the engine to die or rev up due to a lean condition.

Atleast try changing the fuel filters and see if it gets any better.

Just a guess :dunno:

One more thing, I guess the fuel pressure regulator could have some part to do with it too. You can test your fuel pressure. I just don't know how to do it. LOL :)
Good luck

I think you have two seperate issues.
1. Dies while turning.....sounds like an electrical issue maybe...something along the line of what BabyBronco89 said. (could also be in the wireing of the steering column)
2. Idleing up and down...Mine did that and went away when I replaced the TFI. I relocated it at the same time away from the original location at the rear of the 2.9 engine.

Did you check for codes?
Have you tried cleaning the IAC?
