Clean vs replace throttle body
My 2005 that has 93,000 miles has been having idle drop not much but enough that I notice it. My dealer said to replace the tv vs cleaning it. Any input would be appreciated

Just want to reinforce these thought processes. It's super easy on a 2005, and really really cheap. Worth trying to see if anything else, you'd be surprised at how well this works out:
Acquire Throttle body cleaner and shop towels (the roll of towels)
Remove negative terminal from battery.
Remove snorkel.
Remove two electrical connectors from TB
Remove TB with the four nuts (two are 8mm, two are 10mm, go figure)
Clean TB with cleaner, use gentle pressure with a shop towel on the lil' tougher spots, or, what I do, is hold the towel laden with cleaner on the tougher bit to get it loosened up.
Once clean, reverse procedure to put it back on, and go drive for 10 minutes.
It will cost you next to nothing versus a whole new TB, and if it works, you're done. If it *doesn't*, well, you're not out much.

Having said that, you're also at 93K, and it may be that your spark plugs are done, if you've not already replaced them. They will produce nearly identical issues to a dirty throttle body. I happen to have personal experience on that.

Several years ago, I started having problems when I would let off the gas and the RPM's would drop all the way down and bounce back up to idle. Eventually it got worse and would stall, it turned out to be the electronics in the throttle body. Like most have said, try cleaning it first, but it could be the electronics.

Did the throttle body cleaning omg that was not difficult at going for my cruise shortly to see the improvement. Definitely very very dirty. Got all the grime off and really replace a cast iron and brass part they should be ashamed of themselves. Feeling very accomplished. Thanks so much for the help
