hi Scotty, happy thanksgiving!
My car is Ford Transit Connect 2012 with 90,000 miles.
Weeks ago, it had a severe acceleration problem - turned out the 2 catalytic converters & the muffler were all plugged up (as described by the mechanic), so I got the 2 cats replaced but the muffler is currently disconnected - it was not too noisy without the muffler and I didn't spend extra money for something arguably not essential for the performance.
After the above replacement, the car runs okay but I've been sensing rather subtle surging of the vehicle. I cannot feel it when driving over 50mph, but I definitely feel it at low speeds. Also, idling is kinda rough.
What do you recommend? Also, do you recommend replacing the muffler ultimately?
Thanks as always.
