Car: 1991 Pontiac Firebird Engine: 3.8 Transmission: 700r4 Axle/Gears: Dana 60 | Car seems Sluggish Lately....
I am not sure what it is but the car just seems slow to me. I haven't raced it at the track yet so I am not sure if its just me or my imagination. The last time I was at the track I was running 15.7's which is very bad since I have run 15.1's before and that was about 3 months ago. I thought maybe my fuel filter was just plugged (which it was) but it even feels slower now. Think my fuel pump is starting to go bad on me?
I gave it a full tune up, new plugs, fuel filter, did the K&N cleaning, my wires are still good and my fuel pressure is at 11psi and the plugs are a perfect tan. I know my valve seals are going bad cause at cold starts I get a small cloud of greyish smoke. The car has 119,000 miles on it. Think its old age is just showing?This is my mod list.
