My stock '95 Formula convert runs about the same. 14.70 to 15.20's at 93-95 mph. The car is stock auto with 2.73's.

 

my 94 z28 ran 96.1 when stock and 30,ooo miles. with minor boltons i got 99.1 with approx.68,ooo miles. at around 75,000 miles i noticed power down slightly.first check your rubber elbow from the throttle body to make sure it isnt kinked or have resricted airflow! next your compression could be down, a can of engine restore helps(my mph now is98.5 with 90,000 miles). btw how many miles on your car and yes your mph is way down!. i can recommend the restore product as my mph is almost where it was 3 years ago yet car has 22 thou. more miles. car ran 13.96 with totally worn bfg d.r( lousy2.18 60f.t) last aug 04, hope this helps!.btw our track elevation here is 1600 ft. above sea level and my car is an auto which explains the low mph.

 

My car just ticked over 70,000 miles. I was looking at all my records. and 3 years ago, (25,000 miles ago) the distributer, wires, plugs, and waterpump were changed. I dont usually run any additves..except seafoam in the gas, and redline in the coolant. I was thinking about changing them again, but i dont know if that would be a waist of money and time..

 

I would
check for codes
air out the air filter
Take each plug out and check for spark
change the fule filter
make sure your TB is open all the way when you push the pedel all the way down


then run it again

something is wrong for sure.

 

also let us know what happens. I think I like thoes head light covers, where did you get them?

 

I got them online. Do a search on the net for GTS Probeam headlight covers
Thanks for the advise, Im gonna try it, ill let you know the outcome.
