Hi gang

So over the last while after runnning at highway speeds 110-130kph for approx 50kms I would pull off the highway and after sitting at a red light the engine would hesitate and pop (backfire) for about 2-3 seconds and then clean up and run normal. Sometimes the cel would come on only if I run speeds over 120kph and then goes off approx 100km later. Scan code P0101. Now this morning I was driving to work at 110kph and the engine lost power and will backfire if I step on the accelerator to increase speed. Now if I step down hard to engage the downshift the engine will accelerate normally. I am thinking possibly a plugges cataletic converter? MAF? Any thoughts?

Thanks in advance

 

what is the code p0101? it may just be an 02 sensor

 

Cleaned the MAF sensor and all is well...so far.
