Egr???
Hi All,
We are having an issue with our 05 Odyssey, 3.5. The engine had a skip in it at highway speeds this past winter. The last time we brought it in to the shop, two mechanics took it out, one driving and one watching for misfires on a scanner. An occasional misfire was noted on the scanner from various cylinders, but no running issue was noted. After a half hour on the road, the mechanics felt the engine miss and the scanner was picking up multiple cylinders misfiring. After a hour on the road, 5 of the 6 cylinders had misfired.
The mechanic found a note in his scanner stating that clogged EGR ports could cause misfires and rough running between 40 and 70 MPH, however he said he has never seen clogged ports not set off a EGR code and has never heard of this causing a misfire. He also said that other than the note on the scanner, he hasn't seen any mention of clogged EGR ports causing misfires in his research of this problem.
Any advice would be greatly appreciated.
