I have been noticing that when i go thru car wash's that i get some weird stuff going on.The wash i went to today is high pressure and only sprays the sides and front and back of vehicle.Not the under body.I pulled out of the parking lot and floored it and it was almost like hitting the rev limiter about 5 times at 4,000 rpms even tho red line is wayyyy away from that It clears after that everytime, hell if i just drive normal it wont do it at all.It just cant seem to build power past 4k rpm's a few times and is gone after that.Its like a surging/ rev limiter/ miss fire feeling LOL.
I thought maybe water was getting into a spark plug boot maybe.However since it clears after 5 tries i doubt that.Water would stay in a plug boot for sometime.It's almost like its getting into something fuel related.I would think if ignition of any kind got wet it would run like crap for a few hours.I wonder if something in the wheel wells gets wet and causes this ? I have seen a small black relay box that sits kinda on the frame rail in the fender area.I think its on the passenger side.
