Check engine light and vtm light both come on sometimes steady sometimes flashing. Told by several garages including Honda dealer that a misfire shows on diagnostic test. Most resent garage check mechanic states probably due to valves needing replaced which could be a $3,200 fix. No recall but no real answers. One google of problem owners states egr valve replaced with kit and lights went off? not ready to put $3,200 into my truck after almost $3,000 in the past two years.
