So I replaced the MAF sensor, no luck. I thought it was another faulty sensor, so I replaced it again and still the same problem. Turns out my MAF was fine. Everything is hooked up perfectly on the throttle body too. There is such a massive loss of power that I think it is misfiring. If I punch it, it doesn't go past 80 km. I replaced the COPs and checked the plugs and still have the issue. There is no engine light on!! I am at a loss of what else to do.

Clogged cats? 02 sensors?

I cleaned mine this winter and it ran rough for a couple of days AND my mpg went down. It has since returned back to normal however.

Maybe there is a vacuum leak around the throttle body elbow?

I am getting a slight rough idle at times as well. Does not happen every time I idle but once and awhile. I am going to replace the fuel filter to start and then take it from there. Just replaced the Fuel pump driver module last week.

Glad you got your issue fixed!

How did you determine the cats were clogged and what did you replace them with?

Most time it is a small vacuum leak that creates the rough idle that comes and goes depending if you have AC on or not.
