Could it be water in the distributor?
I cleaned my engine on Sunday by spraying some degreaser all over under the hood and then hosing it all off. That was right after I changed my oil (using a different oil filter than I usually do). My car drove fine that night but then the next day after I went and got gas (the same gas I always get) my car started bogging down and sputtering in every gear. I thought it may have been water in the spark plugs reservoirs but I've driven it long enough now to where it would have dried up. Could it be in the distributor? The car drives fine just a little weaker. When idling it only starts bogging down when it goes below 1000 rpm. I know there are a few variables here but does anybody know what the deal is?
