the other day i went to clean off some spilled power steering fluid and antifreeze under my hood right behind the radiator and i now get a cel flash code for the mass airflow sensor. i didn't spray water anywhere near the sensor. at first the car would keeps stalling but after a day everything dry the car just runs like crap. I also have a bad rear knock sensor so between the two sensor errors i now get about 18mpg where i used to get 23-26mpg. has anyone ever had something like this happen. I have no problem if i have to replace the sensors but i have found that they are ridiculously over priced. Anywhere i could get them at a good price?
