I installed a new Fujita cold air intake on my tc. Now the check engine light keeps coming
on every few miles. I've disconnected the battery three times now and it still comes on. Also I have to turn the key twice to start the engine now when it starts cold. Any ideas?

 

the MAF sensor got damaged, or it's placement is wrong for your car.

what year tC is it?

 

Is everything secured properly? Are all of the hoses conneted properly after the install? It IS the correct intake for your year, correct?

After reconnecting the battery, you let it idle for 10 minutes, then take it easy for the first bunch of miles. You've done this, right?

 

I have a feeling it is an 06 intake and he has an 07 tC. I have seen this before on here, or it is the ebay crap that is just a universal intake.

 

thanks its an 07and the instructions they sent me said the intake was an 07 too. ill try letting it idle after reconnecting the battery, i didnt try that yet

 

i also have a feeling that the air/fuel mix might be too lean and it keeps causing the light to go off, everything works fine now except the light comes on no matter how many times i disconnect the battery

 

What brand intake?
I really think the intake is not correct for your car. they may have sent a 05-06 but marked it for the 07.
An intake won't throw off the AFR.

 

i have an 07tc just got the Fujita CAI....I have same problem iv been tryin to figure it out for a week or so....i did everything right...it throws cel at 35miles or 75miles Code reader reads P0101 mass or volume circuit range performance problem ........Have you resloved your issue? is the intake still on?

 

Yeah what I forgot to do was let the car idle about 15 minutes just after installing and disconnecting the ECU. Make sure the MAF sensor is also mounted flush to the piping. Mine works fine now.

 

did you let it sit for 15 then turn the car off or drive

 

i drove it after letting it idle. go easy at first

 

dont mean to ask a million guestions.....but i was curious if ya kn ow how many miles youve gone since you reset everything and no cell

 

at least 300, its been a month since i re-installed it

 

you could try the anti-fouler method or just get a little piece of black electrical tape and cover the light...
