HELP! Have I killed some sensor? NO POWER AFTER Headers and Cold Air Intake

[pasapaca]

This is my first time posting here. Sorry if this issue has been covered before.
After installing headers and C.A Intake. Revs went to near ZERO! actually the engine stopped 2 times. I guess ECU just experimented some strange modification. After 2 days revs went a little bit higher, just enough to keep engine running on idle. BUT ACCELERACION AND RESPONSE ITS MUCH WORST with the modifications. Above all, this orange light indicating some kind of trouble in the gas emission system was turned on for like 4 days. Te guy told me it was because he had to unplug some kind of O2 or emissions sensor when installing headers. In first gear, at not to heavy climbs I need to rev the engine to 4 o 5K just to be able to initiate movement (is it something wrong with the clutch now?) 0 to 60 in about 26 secs!
Anyway, I´m lost here. Just bought and installed new set of pulleys (Microimage) and...well nothing better. Is this usual?
Is it the clutch?, some damaged sensor? Feels like the engine is running with 3 cylinders! Perhaps a damaged spark plug? but why?. Any Help would be greatly appreciated.
Thanks a lot guys!

Here is a link to someone that had problems after installing a 3" CAI.

You didn't say how big your CAI at the MAF was, so I'm just taking a guess that it's 3" and that is why you are having problems. The guy that installed your exhaust header, did he installed the sensor into your new header or did he just left the sensor dangling in your engine bay?

Hope that helps.

What kind intake did you install? ^ and as freedom mentioned might be that too, pics would help too to get this baby back on her feet

Put your stock air box back in and see what happens.

TITANIUM COLD AIR INTAKE 07 08 TOYOTA YARIS 1.5L L4 +HP from Vertexracing.com. (At Ebay)
I´m sure that`s the issue.
to big = to lean,
to small = to rich.
I`ll get a photo, but WeeYari, you are right. I`m guessing Cal too big might be 3". I`ll remove that thing and try out with stock.
Sensor was installed back, but could headers Cal be a problem also?

only if you have a serious leak and you'll know it.

probably that HUGE intake off ebay. you can cut a section out and neck it down to 2.25" and be fine with it. the sensor itself needs to be in 2.25" pipe though.

DID WHAT WEEYAI SAYED AND WORKED. Now, I´m planning about getting he Microimage CAI. Thoughts?

Anything MicroImage sells is quality. I wouldn't hesitate to buy from Garm on any products he carries.
