I replaced and rechecked the gap and plugs which are fine, but the 135 show a misfire. I replaced the thermastat & radiator as well all with in the month. Now it bogs in morning starting for ten minutes and then is fine.

    135 is a o2 sensor code. missfires are the 300 series. it is a heater fault in bank 1 sensor 1. it could be wiring or a bad sensor. get a shop to confirm.
