hi, last night i installed my TBE by "TurboXS" with a cat-delete. this morning im driving by and my "service engine soon" light comes on. should i be worried? why does this happen? i can imaginge the "O2" sensors are not feeling all this air-flow!
seriously should i be worried????? thanks.

 

get the CEL checked.

 

it happened to me too after installing a TBE
all i did was disconnected the battery for 5 min, then reconnected, and the problem solved

 

did the problem go away 4eva?

 

yes it did, only sometimes it appears for few minutes and disappears by it self

 

fo'sho' thanx!

 

good info to know.

 

yeap those O2 sensors can be a biatch

 

Umm, search for "mechanical fix" in the how to forum, you'll find a way to fix the light.

what is happening now that you don't have a catalytic converter, is a bunch of junk that didn't used to get all the way to the second O2 sensor is now getting there and your ECU thinks the catalytic convertor has gone bad.

 

i have the same exhaust but witha hi-flow cat. got the CEL also and did the disconnecting of the battery. it worked for about a day and then it came back on. still on as we speak.

 

do the spark plug non-fouler fix or wire in an O2 Simulator, don't need an expensive O2 sim, I bought this one off ebay for $20, works perfect

If you want to totally remove the rear O2 sensor you need to get the additional resistor for $5 to simulate the heater

 

speedelement sells a mechanical fix for $13 shipped if you don't want to mess with drilling out spark plug anti foulers. it works great.

 

your cars fine just use the mechanical fix or just try the battery solution first.

 

your o2 sensor is reading way to much exhaust flow due to the restriction of your catalytic converter being cut out the picture. search the how-to section for a spark plug non-fouler to plug your o2 sensor in. It works.

 

I have a highflow and my light is on...Should of just got Test pipe if the high flow was going to throw a cel...
