206,000 miles. Threw a CEL with p1131 and p1151 for O2 lean.

I replaced the very old fuel filter and spark plugs today but its still VERY weak on power. It has difficulty getting up hills too.

After unhooking the TPS, it seemed to have a bit more power for a mile or so before going back to being low on power.

Also, under the hood behind the trans dipstick I noticed a silver probe just dangling there. Any idea where that might go?

Thanks for the help!
