I have a 93 grand am sport compact race car and I can not seem to keep the exhaust manifold cool. I run about 2-4 laps and then the manifold is glowing red hot. I dont loose a whole lot of power, but I do loose some. The temp seems to stay fairly cool...I am so lost! I have changed the o2 sensor and fuel filter...nothing changes..Any one out there have any idea of what could possible be going wrong? Wireing? something unhooked? injectors?....thanks in advance!
