Two problems with PT Cruiser

2004 5-speed PT with 48,000 miles.

First, the engine bucks / stumbles badly at about 1500-2500 RPM -
plugs and air filter were changed at 30K, Champion double platinums,
so I think they're OK. I cleaned the throttle body and ran a few
bottles of fuel injector cleaner without helping. Dealer says no
codes, had no suggestions.

Second, the dealer says it needs front control arm bushings on both
sides, and wants an arm and a leg to change 'em, and I need to get
tires soon too. How hard is this to do? I know I could crawl under
and take a look, but it's snowing right now...

 

Replace the plugs wires!!! the lower control arms have been update so many
times you may just want to purchase the control arm complete with bushings
and all. If you are mechanically inclined the bushings can be installed by
pressing them in and out.

I'd price around for those bushings, although here I find the dealer is
similar to places like Speedy.
You didn't get many miles on those tires. Try Michelins.
