1990 190E won't start

Car has been running fine and just a few hours ago it had the lowest roughest idle when I crank it up. I adjusted the fuel mixture on it (richer) which smoothed it out a bit, but when I gave it gas I got no response, if any it was a stalling type hesitation. problem appears to be fuel related, but now my battery is dead from adjusting the fuel and cranking it so much. Why does this happen the night before I have to go to work?!?!

Yep, I guess I should start with the easy stuff first.

It's almost always that ovp fuse, when you have a issue like that.

Just checked the fuse and its fine. Unfortunately I can't even trouble shoot right now the fuel because my battery is dead.

That stinks, like you said start with the basics. Battery, alternator, plugs, wires, cap, rotor. Take a injector out and look at it

1990 190e won't start: Resolved

After recharging my battery and bringing my fuel-air ratio back to spec I found that the throttle linkage was sticking and causing my erratic idle. Thanks.
