was driving my Saturn when it felt like a cylinder start to misfire. Service Stabilitrak came up and traction control turned off causing engine light to blink. Code came back cylinder 4 misfire. Knowing I was due for new plugs and air filter I purchased parts. Go to move inside to work on it and it will not turn over. it had started four hours before. So I dive in…
Found a fair amount of oil/water in air intake hose between filter and intake. Intake had oily coat and could tell heat was burning oil on intake walls. Pretty sure this is not normal? Noticed a hole had been burnt/rubbed into hose connecting PCV to intake/filter hose. Guessing loss of vacuum could be the cause for oil in intake? PCV bad maybe? Moving on to plugs.
I have only changed the 3 plugs at the front of the engine since I ran out of daylight. Plugs appeared to have a little bit of oil (maybe?) on/around electrode. Ignition coils of the three looked pretty decent. Going to attempt to get to the other 3 plugs tomorrow. They made them extremely difficult to get to.
It is a 2008 with 160Kish miles so I’m assuming I’m stumbling upon multiple issues at once. Only other known issue the Outlook has that I don’t think is related but I wouldn’t really know is the evap purge canister on the fuel tank needs replaced.
Any suggestions or insight on what kind of trouble I may be in?
