There'* your problem.
I can't say for sure that I've got a problem with it. I DID check out the performance on the way home from work today. On the way to work, I got stuck on the ramp behind a plumbing truck and a flatbed full of large (approximate diameter 4') iron castings, plus the assorted fittings needed to hook them together. No way to jump on the gas there.

I got around them quickly enough at the top of the ramp, but didn't notice much change.

AFTER work, I got on the ramp and pushed the gas like usual. I used to get up to 65 by the end of the ramp. Today I was up over 80 before I got to the end of the ramp. Gotta watch that stuff. It'* been a while since I had a real ticket. I'd like to keep it that way.

My local Pontiac dealer quoted me $82.42 for a Delco O2 sensor. Online, I found the same part for $39.99. Maybe if they had it in stock, but no, they'd have to order it for me. What a rip!

Where'* the FPR (fuel pressure regulator?) you were talking about?

Again, folks, thanks for your help. It'* tired and I'm late. I've got another long day packing boxes tomorrow.

I've gone back and forth between 10% ethanol and normal in my 92 SSE, and I've never seen a mileage change either way associated with ethanol.

Rock Island? I'm in Galesburg.
When I ran ethanol in my car, the mileage actually went down slightly. Disclaimer: I bought it at Caseys and they only have 89 octane.
