will a 4runner have a misfire do to the o2 sensor onluy having one bolt in it in stead of two
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.
