Having problems with your 2002 Hyundai Santa Fe ?

Car loses power after one or two hours of continuous driving.

\015 After one or two hours of continuous driving, it loses power and start stumbling like if the catalytic converter were clogged, or if very little gas or non gas at all were passing through. After cooling down for a while it drives normal again for another hour or so,then I have to stop the car to cool down for 30 minutes or so (no signs of high temperature). the scan won´t read anything at all,there is no signs of any check engine warning, so my mechanic went trough a posible troubleshooting list as follows; I have replaced the saprk plugs, cables, coils, and air filter. The problem persist and the only thing left to try is to replace the fuel pump and fuel filter, as I have said, I don´t have any sign of check engine light, so the scanner won´t give us a read. Would any of you guys have any idea if the fuel pump could be the problem?\012\012we´ve already checked the Catalitic converter and it´s ok!\015 Posted / edited by AnonymousUser on : 23-05-2022
