we washed our cars today...including the engine bay...we dozed off the grease and dirt from the engine bay with water...My GSR is still running like a champ but his Nisaan Altima( 98) is gasping for breath. Engine is sputtering and Service engine light' is on...the exhaust sounds funny ..

This may be offtopic but would apprecaite your help..what could be the reasons and what can be done..

 

Check all the sensitive electrics for water (distributor, plugs.. etc etc). Good Luck
