I installed a Cold Air Intake on a tC...but the idle is all off and when I rev..it dies..ppl told me that it's the mass air flow sensor.
I unplugged the sensor and it idles better but still not runnin right...

Any suggestions?

Okay, unplugging the MAF will not help your situation. First, did you buy the correct year intake, for example, did you buy an 06 intake for an 07 or vice versa? Second, did you unplug the negative side of your battery after installation? If not you need to. Last, were you careful with the MAF when you installed?

yeah the intake i belive is for 05-06 and i have a 07' tc..and no i didn't unplug the batt. and yeah i was careful w/ the MAF...a tech told me that it might be the sensor that could be dirty and he said that i can try to clean it with contact lens cleaner..the cause of it is bc the intake sucks in oil from the filyter and gets the sensor dirty...otherwise i would have to buy a new one..really don't want to do that..how can i fix this problem of mine?

If the intake is for an 05-06 and you have an 07... you have the wrong intake! That's most of your problem.

And during the install it's a good idea to unplug the battery. You have to do it anyways to reset the ECU. Then when you finish the install, connect the battery and start the car - let it idle for about 10-15 min so the ECU can learn the new airflow from the intake.

do you think that if i just unplugg the batt. after it's installed and plugg it in again..will it reset that way?

Well sure, the ECU will reset... but you still have the wrong intake...

the maf sensor for 05-06 is different from the 07+. Put your stock intake back on and buy an intake meant for your car.

redline760

what would be the diff. on the 06 and 07 intakes..wouldn't they be the same diameter and length??

Spect2K3

its the mass air flow sensor. The 07 and 08 is a smaller sensor than the 05 and 06. They changed it around a bit. The first two years are not compatible with the latter 2 years.

^ Yup... which is why there is an 05-06 intake and an 07-08 intake.

you didn't notice that the MAF sensor flange is completly off?

redline760

yeah i did notice...but i got it in tight..at the time i figured that the sensors were the same..i should have done some research before hand huh? damn.

Varsis

yea that would have helped. Now I'll suggest you head on over the TECH section. Read through EVERY article for the TC in there.
Come back when your done...

Try unplugging the negative battery and waiting a hour and put it back on...........start car and let it idle for 10 minutes and then go drive it gently for a half hour around the area.......do not romp on it.........the thing is learing how to walk agin just like it did when it was new.............I wonped on mine after the install and it stalled.........and it had a weird ticking at idle for the first hour........then presto it works great now..........intakes are tuned and designed to work with your car........and ones that are for other cars or years will not work well........

not to sound like a butt, but just get a new intake

you definetly can't run a 05-06 intake on a 07.....and i'm wondering how you could make the MAF sensor fit.....you have to either get the intake fitted to the 07 MAF sensor size, or get a new intake for a 07....the latter is the better choice

SquallLHeart

^^ i agree, i suggest you take off the intake and get one that's made for the car.

you'll be having further issues if you don't take care of the problem properly

redline760

ok so..the problem w/ having an 05-06 intake on my 07' tc..is the MAF sensor..it won't fit properly right? what if i could get the sensor to fit right? would anything else function wrong or would i be good to go?..i got the sensor to fit.

malibuboy54

the sensor has to fit pretty much air tight.....any gaps. etc will result in a cel or the car won't let you start....

Something tells me you're just not getting this.

Let me spell it out.

You have the wrong intake.
You will not be able to "make it work."
Even if you do, you may be causing more problems.
Put your stock airbox on.
Purchase the correct intake and install.
