Re: '99 Taurus - runs rough when cold
Thanks for the ideas. I pulled the MAF off and ran a bunch of cleaner through it (bought the special MAF cleaner, though the parts-jockey said I could use throttle body cleaner). I also cleaned the throttle body with its own cleaner. I wanted to take the throttle body off, but couldn't get a new gasket in time, so I just did it in place. The car was at a slight angle, so all the cleaner ran back out. Looked pretty brown coming out. I sprayed about 2/3 of a bottle through it, which seemed less brown when I was done. Unfortunately, this didn't help... still runs rough when cold and stalls when I go into gear. If the engine is at all warm, it runs fine. I also noticed that if I rev the engine in park, it tops out at about 4000 rpms; at about 3800, it starts running rough, like its misfiring.
At this point I'm out of time and my wife is out of patience, so I'm taking it to my local mechanic.
Again, thanks for the help!
