Misfires at idle but not at 1500 rpms. Changed plugs wires cap rotor switched injectors and ecu. 1 year ago did timing belt/balance belt and new head. Did a compression check 180lbs leak down test pasted even tried another distributor only misses on number 4. Did a fuel pressure check 50 and 60 with vacuum off.
