the temp runs right below half, i have new accel coil, wires, cap,rotor, ngk plugs,timing at 10 deg, i figure it was good for the high elevation 5000 ft , i drive 4hrs straight with the light on, ive had this car about 4 months and put on about 17,000 miles, it had 153,000 when i got it, i have the car floored 4hrs straight and average 77 -82 mph at 3500 rpm thats all i can get out of her, and when the hills hit it drops to 50-55 mph then shift to 3rd, its a 4 speed, and head winds dont help,
