Having problems with your Hyundai Santa Fe ?
2002 2.4l santa fe
accelerating uphill and check engine light came on. Instant loss of power with loud knocking sound. Engine idles smooth with no knocking but when increasing rpm's the knocking also increases with a decrease in power. Check engine code was PO300 multi-cyclinder mis-fire. Have replaced both coils, wires and plugs. Still knocks very hard and still no power. Checked timing marks, two top marks lined up. Performed leak down test, seemed fine. Timing Belt and tensioner installed D
You should do a compression check to make sure the cylinder walls are good then check the crank position sensor. If the Timing is good and the timing belt is good but your getting misfires on coil packs it's time the check the crank position sensor. If that doesn't tell the computer when to fire the cylinder you get a knock and loss of power.
Hi! Please try this. A faulty torque converter can cause this issue. Try replacing the torque converter and a smooth flawless run will be noticeable. Try it and tell me how it goes. Hope this helps and have a good one!
