![]() When I first start my car it smells like gas and my bbk equal length headers are rainbow colored from the heat. I know people with the same headers and they are not as discolored as mine.
I think that the gas smell is from a leaky injector that leaks into the cylinder when the car is off. The header discoloration may be cause I am runing lean up top or cause all my car is used for is drag racing thus the headers have had a hard life. Any suggestions ------------------ 88 mustang gt convertible bored to 306 BBk equal length headers, mac cold air fender kit, 3.73 FMS gears, Steeds Tri-ax shifter, Steeda underdrive pullies, Custom off road X-pipe, 2 chamber flow masters, cowl hood, nitto drag radials, ford racing clutch, 160* thermostat 16 degrees of timing electric fan off 94' t-bird jacobs electronics cap and wires. Edelbrock 1 1/2 inch drop springs. (Best E.T. 14.79@93mph @3000ft) |

![]() Sounds like an O2 sensor. Get a ford code reader and find out for sure. Mine was 25 bucks from Advanced. Your headers and h-pipe are getting too hot is what the color is telling you.
