Running hot, check engine light on, advise
Re: Running hot, check engine light on, advise
P0108 is an over boost code. The others seem to be misfire codes. Pull the spark plugs and check the gaps as well as what heat range you have. IF you have a 185 you may need to gap the stock plugs down or use a colder heat range. It's hard to know from here in internet land but you need to spend some time and effort being Sherlock to find out what you have.
