So today I was travelling to a friends house driving along normal when I got caught behind a school bus travelling about 35 or 40 mph. As we started making our way up a decent size hill, I noticed my car was lugging a bit and felt like it needed to kick down a gear. Just after noticing this, it kicked down in third and then started jerking almost as if it was bouncing between gears or between the converter being locked up or not. I made it to my friends house with the car randomly jerking from time to time here and there thinking hopefully it would throw a check engine light to help me diagnose the problem but no luck. Anyway, I was able to make it back home (about a 30 min drive) with the car randomly jerking from time to time but still no check engine light. Whatever is wrong with it has also affected the idle as now the car seems to hunt or idle search when in drive. I can still feel what feels like slight miss when idling in neutral but the car doesn't idle hunt in neutral.
So what does everyone think may be the culprit here? I haven't had any problems with the car in the 6 months I've owned it prior to this but I also haven't done any routine maintenance other than changing the oil. I figured I would start with the basic plug and plug wire change although it seems like I would get a CEL if a misfire were my problem. I thought I'd also try a fuel filter just because I don't know the last time it was changed. And last but not least, I thought I might try draining the trans fluid and replacing it. Outside of that, what could it be? I thought maybe the tps but I monitored the tps % via my OBD bluetooth adapter and torque adapter and it seemed normal although I'm not sure there is enough resolution for me to see the blip/jerk as it happens so quickly.
Any thoughts? All help is appreciated as this is my daily driver and want to get it back running right as soon as possible.
