I need some help I have a 06 civic and I put a intake in and for a few days. She’s been running in good condition I did notice sometimes accelerating she would take longer than expected to start moving at a faster pace boy sometimes while waiting at lights for longer than expected or hitting the gas she sometimes hesitates or jumps in once in a while will shut off completely anybody know how to fix this issue

 

What is the trouble code?

Is the MAF/IAT sensor installed on the intake?

 

code p0171 fuel system running lean

And ya the MAF is installed and sealed

 

For P0171, the issue can be due to a dirty mass air flow (MAF) sensor. Get some CRC MAF sensor cleaner to clean it and see if it resolves the issue. Also, re-check the intake for leaks.
