Simply disconnecting battery might not reset the code. Emissions codes are sometimes stored due to fraud when getting inspected so manufacturers of some models make it difficult to erase without scanner.

Clear with scanner then see if codes come back after reconnecting vacuum line.

Update:

Error lights wen out after I connected the little hose where it was suppose to be and everything seemed fine. I even went to autozone and checked for codes a couple weeks later.

But today, for unknown to me reason, they are back on...

Gonna run to autozne and check the codes, but have a feeling they're the same. So the plan is to clean the filter, clean the MAF censor and go through disconnect the battery process again. I checked all the hoses and all are tight and in place, so don't know what is it now.

Only one code this time and it's a P0174.

Erased it with the scanner. Hasn't shown up so far.

Hasn't shown up for a month... Showed up today again... Same one...

Have an OBD2 that I'm running wirelessly and engine performance shows up fine...

The code shows up only when I'm parked, i.e. idling, sitting in the car for a long period of time.

System too lean...

Any help? Please?

My thought is clean the MAF again well and reset the ecu

Didn't clean it the fire. Erased the codes and it was all fine for a month

Thank you!
