So true I was not awake this morning when I replied.The codes are with a PO302 and PO304 And I am looking for the cylinders .I have seen so many pictures and they are all different. I am not using any oil so I am hoping the rings are ok. I have a Muzzler ordered.It has not arrived but will be put on asap.With 180000 on the van should I just replace all of the coils,and I am not sure if plugs have been replaced. I will probably do that replacement too. I plan on having the van for a long time. I am using it to replace a 06 Odyssey with 459850 miles on it. And it doesn't use any oill..I recently had some slippage with the tranny when passing someone.So I have been taking it easy.I drive it smooth and steady and it still goes ok. My last 4 cars have all been Odysseys. But bad luck with them. Had an 09 Odyssey crash when a person ran a stop side. Set off air bag on the side. Ins totalled. Used what they gave me in a settlement to get a 10 Odyssey.It was totalled when 3 deer ran across the road and I swerved and lost control and hit a guardrail .Set off Driver bag and was wasted.Just got the 2012 Odyssey for a steal of a deal for $6200.But has 180000 miles.Which dont scare me.I got a carfax report which showed a lot of regular maint.But not sure of any major work completed,like timing belt,water pump,tighener replaced.So I will get it done at 200000.Thanks for your help.....
