i need help bad. i put long tubes and a t1 cam in my car. Ever since i have had trouble. When you start it up every thing is fine. I take off and it runs ok for a min or two and trys to die and misses bad then it cleans up and is ok till you turn it off. I dont know what is wrong been through 3 sets of o2s. The headers are dynatechs and the cam is a 221 221 .558 .558 on a 112

 

can any one help

 

first question do you have a check engine light? and if so.. you might need to switch your front o2's to the corvette rear bosch number 13111

 

Have you tuned the car since the headers/cam install? If not.....I think we just found your problem.
