Re: 1993 Buick Regal 3.8 rough running

Thanks

Here's the latest

Chacked the spark on every plug and it made it accross the gap with a nice pop snap sound.

Checked the fuel pressure it was OK and there was no miminal bleen down.

we did find a bolt missing on a bracket under the abs unit dorvers side.
It went to a bracket on the tranny housing that had a cable coming from it to the throttle body.
Throttle kick down for the tranny i suspect.

Added the fuel dryer the other day and it really does seem to be running alot better.....
but i can still feel the surging a little still so theres still somthing wrong.
Were changing the plug wires and we will run it aroubnd some more and see if it straightens out.
I think next time we will put some preemo gas in it as well.

thanks for the help.
