I have read everyones threads, and luckily have started to make some progress.

This morning, I broke down and bought and replaced the EGR valve...(201.00) from the dealer...I would have gone throught fastlane, but I needed the part yesterday.

The car roared to life, and I took it for a test drive...IT HAS NEVER RUN THIS GOOD SINCE I OWNED IT! It was nimble, and it purred like a kitten.

When I got back, I was going to put the plug plate back on, and decided to go ahead and replace the plugs with these NGKs metioned above...

I replaced, and sealed everything up....now, I am getting the hesitation again!!!!! I cant believe it! Im going to take these plugs off and go throw them at the guy at Vans Auto Parts.

Anyway, I know now that it was a bad EGR valve... I cant believe how bad it would make the car run, so, this is definitely something you want to check if you are experiencing unexplained misfires, and hesitation. I will post a pic of location and procedure if I get a chance later...I have to go remove that engine plate one more time to change the plugs once again!

Oh getting in and replacing the EGR valve is a snap...takes about 10 min to get it off...and even less time to replace...

Thanks,

Carlos
