has anyone ever ran into anything like this?
the car was running perfect this last wednesday all day long. then randomly the next morning it was idling weird and i went to take it to work and it was nearly undrivable due to a really bad misfire/surge issue! CEL came on and gave misfire and 02 sensor codes. it was bucking like crazy and afr was like 8.8. rpm was bouncing between 500-1500 on its own. i got it back home barely and towed it to the shop and they couldn’t get it to repeat the symptoms after 4 seperate 45 minute drives. they ran the CEL and nothing came of it. everything looked fine to them so i picked it up and drove it home last night and this morning and it drove perfect. after an hour of driving it today it just started misfiring, bucking, surging and ultimately stalled itself as i got into my driveway. let it sit for 30-45 mins and then started it up and it ran perfect again. this was all after a brand new tank of gas on wednesday night, but nobody can figure out why it’s happening.
