Hey everyone, I need a weigh in on some troubleshooting. I have an 03 MDX touring with 316k; that's right 316k on it! I'm the second owner and am having issues with 1-6 cylinder misfires. Misfires only happens upon first start up of the day. Cel comes on along with the vtm.. on occasion engine light blinks. I thought for sure I nipped it in the bud with a recent EGR valve replacement but no dice. Please any help is appreciated. I read about $1000 valve adjustments and I hope it isn't so; she's been great to me but at her milage I'm not sure how willing I am to put that money towards the service.
