truck runs great 95% of time. occassionally on start up at normal operating temp, will run rough for about 10 seconds then smooth out and run great. Also seems to be a little hard on gas. Have tried changing various parts, @ vcv, canister purge valve solenoid, checked for vacuum leaks and somewhat inspected vapor canister without removing it. Any ideas?
