I got an email today from the guy that bought my car. He said he was driving on the highway, and the car stumbles and lost power for 3 or 4 seconds. Its been OK since then. I'd only had that happen when the engine was cold, but I have a feeling the engine was warm. I've been thinking about it, and I'm not sure exactly what it may be. I was thinking dirty MAF maybe? Anybody have any ideas? I'd do a search but I'm on a blackberry and the search doesn't work right on this thing. Thanks.
