Thanks for the advice on my '89 Bronco fuel pump question. Even though the previous owner had replaced the filter, I did it again. Started the truck up, and it still idled poorly, so I went ahead and changed the Oxy sensor as it looked like original with 117,000 miles on it.

I've tried to get the truck to stall out like it did to me before, and as of yet it hasn't. Also, the stumbling I noticed before during acceleration is gone.

One more question, however...I'll repost it to be sure to get the subject field in.

Thanks again, Jon.
