89 740 turbo stalling. I think it may be fuel related. 700 1989

posted by  someone claiming to be olinbrownell on  Tue Oct 26 06:00 CST 2004 [RELATED]

Yesterday, I went out to my car, and had a hard time starting it up. This has never happened before. I drove it down the street to the gas station, got gas, and when I tried to start it, it turned over fine, but would not start. It took many many trys and finally it started. Drove fine. On my way to work today, I was in bumper to bumper traffic, and it seemed fine. I went to change lanes, gave it some gas, and it stalled for a few seconds. It seemed totally dead, and then took off. It gave me that trouble the rest of the way to work. Just when I step on the gas. In the past couple weeks, it has been dying when I first start it up, and put it into gear. Like there isn't enough fuel to keep it running. Put it in park, start it up again and it has been fine. My car has 111,000 miles on it. It hasn't had much done to it. This wouldn't be a timming belt thing would it? I think it should be replaced, as I don't think it ever has. Please help. Thanks.

    Check the airbox. There should be a foam liner in the top of it. If not, guess where it is...
    The foam peels off over time and is ingested by the mass air sensor, the turbo charger, the intercooler, and ultimately, the engine. I had a '92 740 Turbo. The mass air sensor was completely clogged, starving the engine of air. There have been cases of the turbo being plugged and not spinning. Start at the air box and check all the pipes & related intake components. Clean out all the (oil-soaked) gunk. Don't worry about replacing the foam; it is a silencer to quiet the noise of air turbulence.

    Good luck.

    Sounds like a similar problem w/ my 240. Chances are, you may need just the fuel filter replaced (which can be a major PITA to DIY if it's never been done before). Start here as this is least expensive and time consuming. Hopefully that's it. Check my postings/problems for other things to check/do if this is not the problem. Good luck.
