Thje ground refreshing, C101 cleaning for 87 and 88, sensor ground testing, and connector/relay refreshing cannot be overstressed.

First things to do.

 

At idle, reach your fingertips into the EGR and pull the diaphragm toward you. What happens to the idle?

 

Not sure if this is directed to OP or me. Sorry OP I didn't mean to steal your thread, but with both of us working on this issue maybe we will find some answers

Cruiser,
When I pull it towards myself (I'm assuming you are referring to the metal nipple coming out of the EGR valve the engine immediately dies. Diaphragm also seems to be moving no problem while running your Valve opening test. So I'm assuming for me, it would not be the EGR.

 

Good job. EGR is closing all the way then and not leaking.

 

10-4. New ground wires/terminals came in today. Hopefully this weekend I can install to see of that fixes the problem. Already went through the electricala with cleaner. If the grounds don't fix the issue should I look into the O2 sensor?

 

I would replace the O2 sensor just cuz, yes.

 

Thank you Sir, will be ordering this weekend and post results once installed. Looking at NAPA and they have a few differnet ones... any particular brand better than the other? Bosch? Also, should I replace the relay while im at it? It's only an extra $13.

 

NTK makes good O2 sensors. Relays are generic and rarely fail. The connector/relay refreshing should be enough.

Where are you in Az?

 

Ya I did the refreshing so ill just pick up the O2 this weekend. And I'm in Gilbert.

 

Keep us informed.

 

Thanks for all the help guys. Took me a bit to reply because I had to run over to Kentucky and work for a few days. I picked up a new O2 sensor on the way home along with some new fluids and other items. Hopefully I'll get a chance to do that on Monday, while I'm installing my lift kit.

 

"Oddly enough, you are correct."

Check the ground, the 5v feed, and the 12v from the 02 relay, (running) while you are there. That is in the links...

 

You just wake up?

 

The GB Instruments GMT-18A Analog Meter, seems to be able to at least roughly test a Titania (Renix), 02 sensor.

 

I haven't even picked up mine up yet :-(, went junkyard shopping this weekend... or as my fiance calls it "manly antique shopping". Dropped a little over $100 on some misc interior stuff (rear quarter panel, switches, covers, few clocks (hopefully at lease one will work), got some speakers etc etc).

Hopefully I'll get my sensor on Tuesday, definitely keep us posted on and let us know if the o2 was the trick... also I'm extreme jealous you got a lift. My plan was to get my lift next month, but now that I'm getting married, lift is on hold.
