I installed a K&N CAI last night and drove it around for about 40 miles without any problems, I have a MY '00 btw. I turned the car on just now and the CEL came on. I checked all the hoses and they are still attached and nothing is kinked and the hoses are connected correctly. What could be the problem? Any ideas? Any suggestions?

 

- does your car make a strange noise (like something is lose)...
- check the code...
- the only thing I can think of are the two hoses near the throttle body...

 

Same thing happened to me, switch the vacuum hoses (big pointing finger in the picture above) then reset the fuse under the dash, if that doesn't work, bigger problem afoot, but it's probably the vacuum lines.

no strange noises

wouldn't it have thrown the CEL last night if they were wrong to begin with?

how do i reset the CEL?

how do i check the code?

 

- no, it may take some mileage before a CEL comes on...
- to reset the ecu: pull the 'backup' fuse from the fuse box for about 15 seconds, then put it back in...
- to check the code: click HERE.

 

maybe its time for oil change or maintenence, maybe last mechanic forget to reset ? or something

 

Good info dut

 

 

same thing happened to me when i installed the Injen CAI, what we didn't do we didn't disconnect one of the wires from the battery... so what i did was disconnected one of them for like 24 hours and the CEL was gone..

 

Okay thanks guys for all your help dut, you know your stuff. I checked the code, it was something like air mixture. I pulled negative battery lead to reset the ECU, now my next question is, When the ECU is "relearning" the CAI, how long does it take and also how is it suppose to idle? Mine idle is kinda rough then mellows out everytime I go into neutral. I know its now the hoses because i reversed them just in case and the car wouldn't even idle the other way.
