91 300e revving 1500 rpm
 

thanks in advance,

I've a 91 300E ....... I got a car wash yesterday (not sure if this has to do anything with the problem ....... but, here goes:

when I start the car, it at about 1500 RPM and then goes to like 2000 and then keeps going higher .....

I have changed the spark plugs and the air filter about 2 weeks ago .....

the problem started after the car wash yesterday ... not sure if water got into anything .......

any help would be appreciated!
