...roller rockers both are new.? its a 350 sbc, starts and runs great, UNTIL it warms up real good. I will stomp it and when it gets to 55 to 70 mph the check engine light will come on, and will not rev up. When I check the code, throttle position or map sensor will come up and the knock sensor will come up. Can someone help, this is my daily driving truck
