I replaced the eha valve on my 1990 300sel today it was leaking gas. I unhooked the elec.connection unscrewed one of the screws and droped it .So i started the car and backed it up to get the screw.I put the new part on drove the around it ran fine but the check engine light is now on.Is it on because i started the engine without the eha valve hooked up?Or is it the wrong eha valve it looked like the old one and fit just fine and bouth are made buy bosh but i did not check the numbers .Also how do i turn off the check engine light. THANKS in advance Tim
