Scotty, 2001 Chevrolet Tracker with 62k miles.
After its warmed up, it hesitates when you stomp on the gas, sputtering and has a hard time getting up to speed.
Sparks plugs changed.
Fuel filter changed.
Mass airflow sensor changed
"Cataclean" has been running through the fuel system.
What else could be done.
Mike
you need to measure the fuel pressure to see if the pump is failing.
Or it's a collapsed cat like Chuck said (there's absolutely nothing cataclean will do for that when it's in pieces)
What else could be done.
Some actual diagnosis rather than throwing parts at the problem.
You might want to test for a clogged catalytic converter. (There is no reasonable expectation that "Cataclean" would fix that.) Test fuel pressure. Clean the throttle body and MAF sensor. A full diagnostic scan for codes and live data would be helpful.
