I changed my front brake pads and did an oil change on my 2013 Pathfinder. After 2 days of driving I occasionally am unable to accelerate. When pressing the gas the engine does not rev. Usually I can let off the gas and hit it again and it starts going. I've already checked that the transmission fluid wasn't accidentally emptied. There are no check engine lights or error messages. There are no smells or smoke coming from anywhere, including the brakes.
Could be the catalytic converter. Should stop in at an exhaust shop to have it checked. If it is plugged it would be holding the engine back from accelerating.
This sounds like a malfunctioning sensor, possibly a TPS or throttle driver motor, you may or may not get a code to set the check engine light, the first thing to do is recheck your work make sure you didn't accidentally disconnect something in the engine compartment, then if that all looks good then try pulling the codes and see if that leads you somewhere, if that's a no go, then it will have to be "live data" scanned so a tech can read just what the computer is seeing the data stream, then he can tell you what it will take to fix it.
