Hey everyone.
Got a pesky issue going on that I'm hoping someone has an idea about. Two days ago I took my 93 cruiser through a water crossing that turned out to be deeper than I expected. Water was almost up to the engine latch. drove out of it fine and without issue. I stopped to inspect the engine and it was wet but the air filter was dry so I figured I was in the clear. 15 minutes later the check engine light came on. I pulled the code and it’s a 26: running rich. Idle is also rough.
everything I’ve seen on this forum suggests that it has something to do with the vacuum hoses so i did a visual inspection of them and don’t see any visible cracks. Doesn’t mean there aren’t any, but is it just a coincidence that this happened after going through some deep water? Any thoughts on how this issue might be related to a water crossing or do I just need to start replacing vacuum hoses?
Side note: oxygen sensor were replaced just one month ago with new NTK sensors.
Thanks for the help
