We went out to play in the mud and i gor water in my air box. At the time it would not idle and i thaught it was just wet. on inspection i noticed water in the air box. took it to the dealer and had the ecm checked for codes and they reset it. took apart the throtle body abd it was coated a oily dirty coating on the inside. I cleaned it out and it will now idle but it has a dead spot just above idle. Im thinking injectors but would welcome other ideas.

 

Maybe they didn't get things snugged up properly. You might check the connections going into and out of the throttle body to make sure there are no air leaks. That's the only thing I could think of.

 

Make sure the air filter is dry, and not oily if it's paper. A wet paper filter can cause a lot of grief

---The plug on the shifter side is what it might be. When i got mine splashed around in water for just a min and fouled plug. did it anytime i hit water at more then a crawl. I had to fab up a plate like splash guard on frame around shifter. now i can hit water at any speed and no problem

 

is it a dead spot or is it running ruff. is there water in the gas is the connections full of dielec. grease. just a couple of idears.

 

plugs got replaced cleaned air filter. plenty of grease in plug boots. now it runs rough and back fires at about 1600 rpms. runs fine at hither rpm's

 

how did the plugs look when you changed them? dirty, white. if it runs fine on top end then it wont be water as it wouldnt come out of it.

 

do you have a K&N filter. Too much oil on the filter will get on the throttle plates and cause these symptoms. Get some carb cleaner and clean the throttle body/valve. Injector cleaner too. Seafoam works wonders!

 

have you seen k&n's cause problems on these EFI's before?

 

have read a few that had to much oil and dirt build up on the plate and require cleaning from aftermarkewt filters.
