my car runs good any other time other then going uphill. once i start going uphill it slowly losses its acceleration and if i push on the gas to make it accelerate the rpms just go way up but it doesn't go any faster. any suggestions on what it could be?
If it's a manual transmission, it could be a slipping clutch. If it's an automatic tranny, it could be low on fluid or it's going bad. Any dash lights on?
i have had it checked out by many mechanics some say bad tranny others say other things so i am confused and its an automatic and yes the check engine light but when i diagnose it it comes up as a knock sensor i dont even know what that is
Knock sensor is a cheap repair! It changes the timing when it detects a knock...........Up a hill is a perfect place for it to detect a knock...thats probably your check engine light issue............but.....still sounds like your tranny is slipping
