1) Saw the DIY article about the EGR tube into the intake was carboned up. Cool, now what parts had to be removed to gain access? I did not readily spot it during my inital look-see.

Good to know that the Check Engine light is an emmision issue and w/84k mile this me be the source. Sure can't hurt to take a peek and reading the posts may be a good preventative step to take.

2) Now about the turn signal/wiper issue, the combo realy and switch was replaced within the last two-three weeks. Any ideas on this one?

My thanks for the help & humor..he-he.. can use both a a cold Corona w/ slice of lime in it.mmmmm.......
