Hello all, this is a great forum, I have found many helpful ideas. I have the slight hesitation problem at 40MPH that several others have had. I want to replace the gasket on the EGR valve as was suggested in a previous post. I have a 94' SC400, where is the EGR valve and modulator???

 

sense no one is helping you out I will try .... I dont have a SC400 so I dont know where the egr valve is but the modulator should still look somewhat similar mine in my SC300.

 

Here is the picture of the EGR valve.

 

Thanks a lot guys you've been most helpful.
