Hi, So for 15 years plus I refused to wash the engine compartment of any vehicle I owned. I broke my own rule the other day and washed the engine on my nitro, from a safe distance. Afterwards it wouldn't run properly, sputtering away and jerky at red lights. I changed the spark plugs and it runs great now. Except now at around 80-90km/hr under general acceleration it sputters for a second. Any thoughts on what the problem might be. Thanks.

 

Rockymountain,

Any number of components could have been affected by the water.
Quite likely some electrical components were exposed, possibly wiring or connectors.
Also, check the air filter and air box for any water.
Perform a visual inspection to see if anything is apparent, have it looked at by your dealer if you can't find anything.
