Hi, i own a 2004 2.5Rs and whenever i accelerate, there's a popping noise that i can hear. Also, it feels like the car is being restricted of it's power when accelerating then would suddenly stop the popping and accelerate normally until i change into a higher gear. When idling, the there's also popping coming out of the exhaust. The car is fully stock. This is the only information i can give you guys. Sorry. Please help :s

****Not a mechanic nor know anything about cars. I was searching Google for solutions and came across this website****

Thank you!

Sounds like your misfiring. Any codes being thrown? Similar situation happened to me back in 2011. Ended up being a broken valve, had to rip apart the motor and fix her up.

Well, your car is running rich for some reason. Pinpointing the cause is a tricky though, since so much could cause it.

I'd check for exhaust leaks, check plugs, and plug wires.
