98 4Runner Hesitation Question
Trying to rule out problems with my '98 4Runner 3.4...
Here are the symptoms: Major hesitation on acceleration after initial start-up. If I rev the engine in neutral and put it in drive while I'm driving, it seems to help--i'm able to drive long distances, stop&go traffic, etc, afterwards.
Recently broke down in the woods after a branch smacked underneath, but got it up and running (unknown) the next day. Couldn't find anything wrong at the shop--02 sensor malfunction, but I have no catalytic converter (somebody stole it) and just have a straight-pipe to the muffler.
Replaced the fuel filter. Air filter looks fine, all fluids are good.
What are the symptoms of a bad 02 sensor? I'm also wondering if I knocked something loose in my fuel tank and my pump is acting up?
Any help would be great,
thanks
