Hello, My 1995 E320 wich has been running fine untill I washed the engine... I removed the water from the spark plug chanels etc so everything is dry... It has been driving just fine thill this morning the Check Engine Light came on at startup and did not go off... Is there any thing that I should check right off the bat??? Coolent seemed to be at a good level. I have not checked the other fluids....

If anyone has a suggestion I am all ears!

Thanks,

Hal
