Twitch de la Brat Posted February 22, 2010 Share Posted February 22, 2010 I've been having some odd symptoms with Xandra. Her specs are 90 body legacy 293k miles, 91 engine with 250k with about 10k on a full top end rebuild, and a 94 5sp with about 250k torturous miles on it. She seems to be running rich and stumbling when cold. And I've been getting an occasional CEL. I chalked this up to a bad O2 sensor, but last night, she died when I pushed in the clutch pedal. And I'm sure this can't be from just a bad O2 sensor. I've had no problems other than the rich running and stumble. Any ideas?

Rooster2 Posted February 22, 2010 Share Posted February 22, 2010 How many miles on plugs and plug wires? If old, I would replace them. Add a can of injector cleaner, the good stuff costing about $6/bottle, as in Chevron Techron. The cheap cleaner does little, just wastes your money.

Twitch de la Brat Posted February 25, 2010 Author Share Posted February 25, 2010 Well, I replaced the wires and the plugs when I rebuilt the heads. But I discovered my problem. My smooth idler pulley had failed sometime ago, but the belt was still slipping past it, allowing the car to run. Well, that pulley finally completely self destructed and there went my timing :-\ Thankfully my engine is non-interference, so it was ok, but I got stranded at the local napa, figures right? Purchased a timing kit + water pump for only $117! I learned my lesson about replacing the timing pulleys... Thank goodness my BRAT doesn't have those...

Twitch de la Brat Posted March 17, 2010 Author Share Posted March 17, 2010 (edited) I was wrong about it being a smooth Idler pulley. It was the toothed pulley right next to the water pump. It had failed and the bearings went away fairly quickly. But there was still enough tension for the car to keep running, soooooo the outer race just rode against the inner until it shaved off enough metal to make the belt lose all tension. I have the thread right here. It shows all the carnage. So the new bearings fixed some of the stumbling, but I finally swapped out my O2 sensor with a used one I had sitting around. It took a couple miles to get readjusted, but it did. Then I went and had fun. Lets just say Xandra got a little dirty Twitch Edited March 17, 2010 by Twitch de la Brat Quote Link to comment Share on other sites More sharing options...
987687 Posted March 17, 2010 Share Posted March 17, 2010 I wish I took pics of when my water pump seized (at 92k!!). It was pretty gnarly looking. The belt was in about a thousand little shreds, and all but 1 of the idlers sounded like 30 year old skate board wheels. Quote Link to comment Share on other sites More sharing options...
