I washed my car at lunch yesterday and sprayed under it well to get the salt off. Now everytime I start it my CEL blinks 4 times. It idles high for about 30 seconds and then almost dies. Once it picks up from almost dying, it seems to run fine... Anyone know what 4 blinks means off the top of your head? I have a code reader at home, but am at work. Just thought someone might know what 4 blinks means. Im guessing something with the O2 censors, since I sprayed under the car... Thanks for any input.
