I got 91k on my car automatic 3.9l and has never given trouble until now. I recently made a trip from CA to TX 1,800 miles each way. 200miles into the trip I noticed the car beginning to hesitate when I accelerate. It only does it when I accelerate. I thought it maybe the fuel filter so I changed it and it keeps on jerking. The problem is consistent and I'm afraid of developing something more serious. A friend thought it maybe my catalyst converter that was plugged. I'd like to avoid trying to guess at what it is. The engine light hasnt turned on so I'm pretty sure the mechanics w/ code readers would get nothing. Any ideas what it can be.
