I have a 2003 Honda Odyssey EXL with over 200k miles. I have replaced the motor mount that was bad and the power steering pump in recent months with no issues. I just drove from Nebraska to Idaho recently, with no issues on the drive. After being here in Idaho for about 2 months now. My car has always chugged (?) while idling at a stop light and I've thought nothing of it. Recently though while driving on flat surfaces, I will step on the gas to accelerate past 25 mph, and randomly it will stop accelerating, the rpms will rev to 3k rpms, the car will jerk and then it will start to accelerate slowly, but start the whole process again, slow to accelerate, rev up rpms, jump and accelerate slowly. I know I probably need to change the spark plugs and wires but I'm hoping there isn't a bigger issue at hand. Has anyone else had this issue? My best friend uses my van to drive to work everyday and she hasn't had any problems. It only seems to act up for me. The last time this issue happened the TCS light and check engine light both came on. Once I got home I shut off the car and turned it back on and the TCS light was off but check engine light remained, have not checked to see what it is on for yet. Just wanted some ideas about the overall situation first.
