From different thread with changing oil viscosities in my daughters '08, 247k mile CRV with some slightly rough idle at times and slight lack of power from butt dyno. @cptbarkey mentioned trace the problem so here is the plugs and coil packs. I'm looking for thoughts from those that change plugs often and have seen many things. Vehicle runs well, doesn't burn any oil that I can document and have never needed to add. It's currently on first run of VRP 5W-20. Air filter just got changed today, wasn't very dirty anyway. MAF and TB cleaned. I think the slight rough idle is more AC kicking in and a slight exhaust noise. Trying to get that also to shop.
She has mentioned and I noticed more crank time on first start of day, like 8-10 cranks instead of usual 2-3 rest of the day. I suspect possible fuel pump/check valve losing pressure. Still need to get that checked.
Plugs are NGK Ruthenium. They have been in vehicle for 5 years and 40k. It has seen multiple cans of Gumout Multi system and BG44k over those years/miles. Plugs 1 and 3 came out harder than 2-4 maybe from carbon etc. I cleaned threads and all went back in nice and easy with just 2 fingers spinning the socket/extension and then retorqued to 16 ft-lbs. Fuel is mostly Exxon/Mobil with some BP and Shell and mostly 87 octane.
Thought on if they should be replaced? Overall running? @Trav if I thought of replacing injectors for ones that don't have 247k any links you would share. The ebay ones kind of scare me at 4 for $50 even if say genuine Honda but $50-80 each seems a bit out whack also.
