After install Aem Cai for 2 days, these engine lights popped up. Anyone know if this is serious issues. Should reinstall the stock Air intake? Or just reset the light?
Thank you

First thing, Pull the stored OBD2 codes. If you don't own OBD2 reader, or can borrow one, many auto parts stores (Autozone, for example) will do so for free.

Make sure the CAI doesn't have any open ports (leaks)

Thanks for the reply, I just double check on the Cai, and tighten everything again. Hope this will solve the issues.

...make sure to reset the codes as well...pull the battery cable while you're going over the CAI connections...will give the computer time to clear any existing codes

 

[Blazinmd]

Yup, I cleared the code, just took it out the highway and floor it, everything seem OK no engine light. Also I grab a OBD II on Amazon just in case.

After fishing trip today, the engine light went on again. Just my luck the OBD 2 I ordered from Amazon also arrived. This is the code after I run the test.

Too lean tells me it's pulling in too much air...you sure you got all the leaks plugged?

 

[Blazinmd]

Yeah, I probably need to reinstall the Cai again. Look like there a leak somewhere. Its a relief just a Cai issue, instead of something more serious.

Highly suspect MAF, since you would have had to remove/reuse during CAI install.

Suggest you disconnect harness, unbolt sensor from tube, and carefully inspect it.
It can malfunction if it is not extremely clean . . . you can use something like this to clean it before reinstalling:

Then carefully reinstall, verify sensor fits tightly against tube.
Reattach the wiring harness, verifying it is snugly installed.

To check for air/vacuum leaks at vent hose or hose clamps, start the engine.
Take an ►►UNLIT◄◄ propane torch, partially open the torch valve so some propane gas streams out,
and point the torch tip around the sensor, vent tube, and band clamps near engine.
If engine RPM increases, you found location of your intake leak.

I just cleaned and resinstalled the Cai, now it made a hissing sound as turn off the engine, is that normal?I have run the OBD 2 test,and no codes.

Common trait and trade-off with virtually all aftermarket air intake systems; the straighter the intake pipe, the more pronounced the hiss-ss-ss.
You removed the stock intake system resonator that quiets things, so now you have a 'straight tube' megaphone from the throttle body.

Thank everyone for inputs, especially PANDA for the knowledge. Turn out there is a leak at the cone filter connection to the pipe, i had to tighten with the ratchet instead of the flat head screw driver. Everything seem good now. gotta to love the V tech scream.

Agreed. There is nothing like it. Takes me back to the days of my ‘91 integra hitting redline about 8k rpm or the older Si’s. Not the fastest cars but the sound and experience of those motors was intoxicating. With that said, this motor/trans combo is spectacular imo. A joy to put the pedal down.

For some reason Borla and Magnaflow haven't make after market exhaust yet. I have been waiting a year now.

Did the problem ever come back?
