Engine Mechanical problem
2000 Nissan Altima 6 cyl Two Wheel Drive Automatic 169000 miles
----------------------------------------------------------------
I have 2000 altima. I took it to the car wash and cleaned the engine with the engine cleaner. the next day the engine sputters and car does not go over 30mph and the engine shakes and muffler sputters.

disconnect all sensors, dry off the connectors.

just anything that was electrical that got wet, has to be dryed.
