What intake? Once is a Rich code, MAP code, and MAF code.... All point to fueling.

It's just an eBay one but it has been on for a year and a half with no problem. Could it be an injector? I'm thinking about Ottp stage 2 but kinda want to fix the current problems.

Tune, also check for a crack in the cai. And also if it was raining and this occurred this is normal, mainly due to condensation hitting maf

Sometimes even though it is a new sensor, I have had problems with the manufacturers of the filter putting too much oil on them. Even just a touch of oil on the sensor will throw a code.

The one that comes back the most is the p0172. And it come on when its not raining. Sensor is new like 2 days old filter is a couple months old so there is no oil on it. My guess is its an injector. I was just hoping someone had the same issue. But I don't want to buy new injectors for no reason. All of this started to happen after I did my clutch. Had no issues before. I don't know why that would effect anything.

jba290,

It looks like you've been getting a lot of great input from the community, and I wish I could be of more assistance when it came to how-tos. If I can look into anything for you (warranty/recall information), please don't hesitate to send me the last 8 digits of your VIN.

Best,
