'88 300 E, won't idle-- Help!
Hello again... I fully understand the importance of getting a repair manual for my vehicle, but I haven't really had the chance.. Damn thing is a workhorse, but I have also been recently.
I'm working a ton, and driving a lot more, so naturally more problems have arisen.
Here's my situation.
I was driving home late one morning, and I drove over a little pothole. Nothing huge, to make me think that it caused this-- But I basically mention that just for time reference.
Sometime within the next minute the car started laboring and making a hard bumping sound. At first ear-- I thought I might have fucked up a tire or something. So I immediately pull over to a gas station to check 'em. Everything is fine... i get back in the car and notice some pretty rough fumes coming from the engine.
I start to roll down my windows for the ride home, and as I lowered my window my battery and car just DIED with it.
I started it on a jump, but it kept dying when the RPMs would come back down 500.
It was a real bitch getting the car home, and not really being able to stop it. I couldn't take the risk of the RPMs dropping and me leaving me stranded again.
So I am pretty lost. My car starts just fine, but the engine dies whenever I leave it to idle. The engine sounds a little rough, when I'm holding it around 1000.... I've had a few people tell me--- alternator issue, vaccuum, or even a busted cylinder. But the latter two really don't make a lot of sense to me, because-- why did my battery die when I rolled down my window?
I'm going to the mechanic tomorrow. Any ideas you guys have would be greatly appreciated. Help steer my guy in the right direction.
