1996 Running Slugish
 

Hi all,

I have a '96 Deville Concours with 125K miles on it, it's been babyed since brand new. I recently purchased the car in September and it ran perfectly. I replaced the EGR Valve, altenator, raditor (general maintence issues). I always run hi-test fuel and even race fuel from time to time with plenty of fuel additives. This past week it just seems to be running somewhat sluggish and I can't put my finger on why. Does anyone have any ideas?

Sluggish
 

Have you checked for Vac. leaks, plugged cat.,or low fuel pressure??

I have, everything checks out to be fine and in working order. I'm wondering if it has to deal with my transmission, I don't know much about these Northstars.

leaks, plugged cat.,or low fuel pressure??

Thanks everyone. I found that my problem was in the transmission along with crappy gas. My transmission was a little low on fluid, so I put Lucas Transmission treatment in and it's back to it's usual self.
