Unexplained Limp Mode

street2soul · 02-01-2017, 07:16 AM

I need to add#4 to limp mode.

4) MAF code P0101, P101B
possibly related to K&N filters oversaturating the MAFs and damaging them.. I've changed back to dry filter, changed MAFs twice, and still having this problem intermittently. went to different shops, nobody knows how to fix this. I am told that throttle bodies are probably not the culprit and waste of time cleaning. but there was a thread about people reporting the same issues and cleaning throttle bodies fixed their limp modes and codes related to the MAFS.

1) when I bought it brand new and drove home, engine was breaking in

3) low engine oil
