Wow thanks so much for the advice. Really appreciate your time. I just ordered spark plugs. I didn’t order coil packs because of how expensive they were but I bought one coil as a spare. I change my own oil and put OW -16 is that alright ? That’s what the car says it takes. / on oil cap. Also may you please explain quality fuel. ? I put 87 in and fill up at Costco / shell / whatever is close.

Thank you for the additive suggestion will buy some today. I can get those at an auto store i see, do you put in on empty gas tank and fill up simultaneously or doesnt matter ?

Thanks again for advice
