V2 installed -- Check Engine Light???

So Everything is cool until I stepped on it to hear the V2 growl. Next thing I know the Check engine light started flashing. It went off. Today i was driving on the interstate and floored to get on the on ramp and the check engine light came on and now STAYS on.

What is going on?? Any suggestions?

Thanks

i would check the opening where the throttle body meets the v2...see if some plastic is stuck on the ends. if that is the case, everytime you step on it, the plastic piece or any tape would get sucked into the throttle body, throwing off the comp.
(happened to me when i bought the car, from some shady dealership....who wrapped tape around the throttle body)

the bolt that i put in the side of the V2---i left out the O-ring on it because it was very shi**y. Think that would be a problem?

Yep, that's probably it. You're probably sucking air in and it's screwing with your sensor. I'd get a new rubber O-Ring pronto. I bet that's your problem.

i put like bolt sealant on the bolt instead of an O ring. I did this because when you tighten the bolt, the O ring just squishes out and serves no purpose.

just disconnect the battery to turn it off... then replace the O ring.

the light actually flashes due to an emissions problem (since you put the V2 on). so it shouldnt mean anything harmful to your car.

other then that, maybe its coincidence and has to do with something else. i could see it being the what people are saying... Either tape or whatever sucking in when you gas it

did you touch the coolant line and vaccum line that is attached to that aluminum bar thing... the vaccum line if run directly will yield a cel

I havent had the problem since i disconnected my battery. it flashes sometimes if you step on it, but it usually goes off. i have a friend who is a honda tech. and he said not to worry about it.

Well ya, I re-routed the coolant and vacuum lines like the directions said. I didn't screw anything up, just placed a new hose to re-direct everything.

Is the light flashing or is it solid? Flashing, without looking at codes based on my experiences it usualy means cylinders misfiring. Check the codes stored just to make sure.

If you're that worried about it, I would just go take it in for diagnosis, but that will cost a hundred or so just to see what's wrong. Other then that, I don't think it's a huge issue. Obviously something happened while installing, and I can't imagine it being something too harmful.

Go walk around the garage at honda and try to get someone to stick an obd scanner in it real quick lol. I've done it, cool guy.

The flashing CEL is usually an indicator of mifires random/multiple...It happens because the Crank Position Sensor sense something it doesn't like during VTEC crossover, they do have a TSB on it I believe and replacing the sensor took away this issue in my case...as for it staying on solid, I have no idea.

LOL you should not modify your car if you don't know what a CEL is.

ok ignore the coolant line but put the vaccum hose back the way it was with that metal bar you took out

I got a cel immedietly when I followed the directions, cut a hose in 2" and put it with the metal bar there and the light went away right away, i don't listen to instructions lol

Installed a CAI on my friends car, and the check engine light came on, got an obd 1/2 code reader and cleared the error code that was causing the check engine light, no more light, cars fine since then, pick up a code reader and save some money next time ur light comes on

Also, how close should the intake be next to the throttle body. There is prob like a 1/2 inch gap inside the rubber gasket btween the intake and the throttle body. Should the intake be touching the throttle body or is a little space between ok?

THANKS!
