Hi Scotty, 2002 Chevy Suburban 5.3 gas with 173k miles. No codes generated when service engine light blinks at over 2200 RPMs in N P or driving. Scan says cylinder 5/855, 6/13760, 8/211 no other misfires. Have cleaned MAS, changed plugs/wires, new fuel, new air filter, changed oil. Runs great even at idle but keeps getting service engine light blinking at over 2200 RPMs. Any ideas? Crank/cam shaft sensor? Injector/coil? no loss of power noticeable...thanks Scotty!
