My 1999 Chevrolet Suburban has an intermittent miss and rough running above 2000 RPM. It seams fine below that. It is flagging a code of P1153. I just put in new spark plugs
, wires, rotor and distributor cap. This did not help to smooth out the engine

Customer: I do not have a wiring diagram, but can check fusses.
JA: What is the model of your '99 Chevy?

JA: OK. Got it. I'm sending you to a secure page on JustAnswer so you can place the $5 fully-refundable deposit now. While you're filling out that form, I'll tell the Chevy Mechanic about your situation and then connect you two.
