HELP CODE 92, how to test egr circuit?

Hey, someone mention my name?

Yes, back from the dead, more or less. Did a google search for my user name since I had a eBay auction that got a thousand or so views and saw this. Haven't been on here in two or three forum upgrades but still see the same sinners preaching the gospel God why all the advertising though?

JSS, play nice. You're just chasing your tail like every other stanger out there. Note that the aftermarket Bosch O2's with the '-492' part number aren't that great. I just went through a couple trying to get two that worked correctly. Your best friend with these 'problems' is an air / fuel gauge and a three way switch so you can monitor both o2's to make sure they are both sweeping correctly. My '93 got the cackle cackle cough cough a couple weeks ago, drivability went away. It was either WOT or gagging. The regular o2 was ok, but flipping to the other o2 and it was reading lean. Swapped out both with spares out of laziness (didn't feel like unplugging one to see which was bad) and managed to put another dead one in it's place, but it read rich all the time. Third time on the jack and I put the two good ones together and the car runs like brand new. BTW, my car always want's to code for something, but I always have a hard time getting the code reader to read.

In other news I chased a WOT problem with the ranch for a couple months until the stock '88fuel pump died on me and I put a 190 in. Made a huge difference in sound and performance, even lost two MPG with the new pump. Methinks it was bad for a while...
