Hello, I have porsche cayenne 2013 V6 3.6. I have rough idle/shivering after I accelerate full pedal on the highway and then when i stop at the signal, it starts to shiver, more like rough idle when stationary. I changed to delphi coils & bosch plugs but still issue remains same. But no issues while I drive normally. Computer diagnosis shows cylinder 3 and 5 misfire. Please advice.

Hello I noticed my car stop accelerating once it gets to like 60miles/hr. There is a sluggish and lags as it gets to 40miles/hr but once it’s get to 60 it doesn’t feel like it’s moving up. Could this be a misfire

Hi!!! Good day

Question, Can fuel Quality affect as well?

Most of the time it is a burned out spark plug. Rarely the coil pack. Also, it can be the Cats. When I get a misfire. I pull over turn off the engine, and it goes away. This can happen if you redline constantly too
