CEL with Skunk2 Mega Power

[adoBoy619]

I just put a Skunk2 Mega Power R on my 07 Si today... to go along with my Injen CAI that i've had for about a month. I got a CEL. I checked the bolts to make sure they were tight. But the light stayed on. Im not sure though how tight I should make the bolts (which i think is the most likely problem)...I hand tighened them but i dont want them to break....how tight have you others made the bolts? Also, wouldnt I pretty much know if there was a leak? I probably wouldnt get no real power...right? Or is this engine light normal for the first few days or so? I had the bad smell in my car and it went away after about an hour drive and a bad headache...but thats taken care of...soooo...any thoughts?

You may have damaged the O2 sensor upon install. DId you just put the exhaust on or a header or test pipe or high flow cat? I just install it on saturday and no check engine light..

All i have is the Injen and Catback. I didnt hit anything except the cat bolts...pretty damn hard too. could that process shook something up?

Yes the CAT could have moved and banged one of the sensors??

sounds like u have a bad leak have some one sit in the car and rev it while u look underneath during a cold start u might be able to see some smoke escape. id check that before anything though. maybe the leak is causing the the o2 sensor act a lil crazy giving false reading and so throwin a cell

when i did my catbolts i thought i had it tight but it turned out that it wasnt tightend so well i brought it to a shop we lifted it and lightly tightend them. but not sure on how tight they should be.

wouldnt i lose back pressure if there was a leak though...my friend had a crack somewhere on his exhaust and the result was his car moving slow as hell

[jay3151]

maybe maybe not depending how bad ur leak is.

ok..i get what youre saying...imma check it out for leaks tomorrow...i might try and spray some soap and water on the connections and see if they bubble...if so...BAMM...gotta tighten some more

[adoBoy619]

went to auto zone yesterday...02 sensor 1 is the problem...now question is...should i change it with another one or use a defouler? i was told by somebody else just to unhook the negative side of the battery for 15 minutes and run it idle after i hook it back up...and it go on but go out after a few mintues in idle...sound about right?

just got back from honda about the third gear problem... they decided to check out my O2 sensor. Looks like they are gonna cover that under warranty. Nice Guys
