will a 4runner have a misfire do to the o2 sensor onluy having one bolt in it in stead of two
3 Answers
No.. as long as the O2 sensor is firmly mounted (1 bolt or 2), it would not have any effect on the ignition system. If it is a bad 02 sensor, then yes.. It's a possibility.

ok my 93 4runner had a bad head gasket I changed it and fallowed the book to the letter other then the vacuum lines I thought I had just finished it up till I took it for a drive and it started jerking I changed out the injectors coil plugs wires cap and cat converter but I still have a miss its not as bad after I changed everything but it still jerks every so often what could possibly be the problem
This is a total shot in the dark, but did you try replacing the EGR valve? A clogged or gummed up EGR valve will cause rough idle or hesitation on acceleration.
