Believe it or not, for the first time in 185K miles, I adjusted my TV cable and cleaned my throttle-body and IAC. Both the throttle-body and IAC were very gunked up. I spent a few extra bucks on the "Throttle-body Cleaner" rather than using carburetor cleaner, to err on the side of caution. The only thing that was really noticeable was that my shifting from 1 to 2 came at lower RPM's, around 2,000, where any change in the 2-3 upshift wasn't really noticeable. It does seem to shift smoother, which I guess stands to reason at the lower revs. With any luck, my mileage will improve a touch from both of yesterday's jobs.
My Jeep is still losing power when pulling moderate+ grades. I'm pretty sure it's a somewhat clogged cat. I'd like to verify with a back-pressure tester, but figure I might as well put the $40 tool cost into a new cat. The rest of it should be paid for by the recall gift-card. Of course I'm sure I won't see that for months. I don't think it's a bad fuel-pump, as the Jeep will give me RPM's and power if I go into passing gear. That would seem to be counter-indicative for a fuel-pump problem, no?
