I Have A 2002 Chevrolet 1500 v6 Pick Up And When I Accelerate Hard After 70mph The Service Engine Light Will Start Flashing. What Might Be The Problem?
Go have it scanned,this is the only way to know,why the light is flashing.If truck run,s normal,then it just may be a bad sensor,but could be trying to tell you something major,is wrong.
Have you tried replacing the fuel pressure regulator?
