Kyl, Never recommend clean a MAF unless you are willing to buy them a new one out of your own pocket.l Rovers Bosch MAF does not take well to a cleaning.

just had those same codes after stomping the gas pedal...(been checking codes and pending codes every 5 mins or so while driving)

replaced the MAF and codes are gone

not suggesting you run out and spent $120 on a new MAF, just a suggestion as to the cause of my issue (same codes)

here might be a way to check if its the MAF....reset CEL then watch an obd2 scanner (on drive cycle monitor)....if only 4 monitors come "ready" instead of 7, after say 50 miles of driving, then its probably the MAF...that was the problem i was having.

after replacing maf drove 20 miles for all monitors to be ready

 

just noticed this thread is 3 yrs old....hope you fixed it by now
