My O2 MDX has 230,000 miles . All cylinders
misfire. Read on here that it was the valves. When checking
my valves should I go ahead and replace the timing belt?
When was the last time you had a tuneup? How many miles on the current belt?
I read in an Acura forum it could be the spark plugs the coil packs or the valves are offset. I've changed the spark plugs are changed the coil packs I still have the check engine light come on. So now I have to check the valves and while I'm there should I go ahead and change the timing belt its at 230,000 miles.
