'94 854 n/a, 148,000 mi.; it has started running rough at cold start (a "chug", I'd call it). Get it on the road, or raise the RPM's, and it smooths out. No power problem, low or high end.

However, cold or warm, coming up to a stop sign, it will start stumbling again, and if I stop hard, or brake into a turn, it will die out totally. Did it twice yesterday, once turning to enter a freeway, and once in a 60 degree turn at about 30 MPH. Starts right back up, and drives down the road just fine, but it's a little unsettling to die in a turn and lose the power steering.

Feels like some sort of a fuel problem to me, as it acts starved when it starts running rough. If it had a carb, I'd suspect a float problem of some sort. Throttle body was cleaned about 5 K back.

When it idles rough, and I run it up to about 2000 or so, and let it back down, the idle smooths back out. But, get it on the road, and start braking and shifting the weight, and the stumbling starts right back again.

Any thoughts, folks ? ?
