Serious stumbling

[Larry C Leung]

Musta missed this thread. Who is Dr. Vinyl? (Need some help with this
myself).

As for the stumble, you don't state the car, but if it's a turbo, check
for the infamous vacuum leaks, all hoses, and the intercooler. If N/A,
vacuum leaks tend towards hunting idles.
