P1128/P1130 Codes

[uabchris]

My check engine light came on and produced P1128 code about a week after the dealer had the engine out for RMS and clutch. I researched a bit on this site and checked the oil fill cap (a bit loose) so I flipped the o-ring and it fit snug and tight again. I cleared the code to see if it would repeat and it occured again about 500 miles later producing P1128 and P1130 this time. I am running a K&N with about 60K miles on it and just cleaned and re-oiled (carefully) :unsure: ....which I have read can kill a MAF, I have a std filter on the way. Before I take it in to the shop do you recommend cleaning the MAF (148K) off the vehicle with the CRC brand(or comparable) MAF cleaner? I heard a few bad stories about trying to clean. The car runs great with no power or gas mileage loss. 3 of the 4 Oxy Sensors have 148K on them.

You can screw anything up if you do it wrong

but cleaning a MAF is a 15 minute job, costs about $5 in cleaner and is easy (assuming you have the right tool and even that can be had for $7).

Do it carefully, handle it by the right parts and you'll be all right.

Of course the probability is that there is another problem and it isn't the MAF....
