UR TestPipe with CEL??

[EVIL_EVO_VIII]

Last night i installed the UR test pipe. After turning the car on, it was fine there was no CEL. Went to get gas and after i was done i started the car and i got a CEL. I disconected the batt and reset. Nothing came on, i shut off the car, later i went for a drive and got the light. I believe i have installed it correctly. I have the 02 bung sensor facing towards the front of the car on the passenger side of the car. I used the extra wires provided to extend the oem ones. I know there are 2 black wires, does it matter which one i put or do they have to be put in a certain way?Dont know if i have them mixed. Any advice?? I used the stock gaskets in place but dont think its the issue. I havent checked the code yet to see if it pertains to the testpipe. The car definitely pulls real hard now :D . That stock cat really does restrict the car.

Well, a CEL for rear O2 sensor efficiency doesn't trip until 60-70 miles or so, at least in my experience. My guess is you have some wires mixed up and the ECU isn't getting a rear O2 signal at all, and it's throwing a CEL immediately.

Well, last night i reset the ECU again. there has been no CEL sinsce then. The CEL might have been for something else.

Autozone will pull codes for free, in hope you buy thier stuff. I would be safe and just get them pulled next time.

You should not have reset the CEL without pulling the code first. The thread is pointless without knowing what the ECU had a problem with. Could have a more serious problem but you're telling the car to STFU and forget about it.

Well last time before installing the TP i threw 2 CEL and they were due to the cold weather. When i put the TP on that night it was as cold also. I reset it yesterday and it was warmer so im pretty sure it was the same reason as before. But thanks for the concern. :D Mike had told me he was also getting codes during cold weather because of sensitivity issues with ECU

Hey Miguel, get a monitor Gauge. You are boosting and with no idea what is
going on! In this cold weather, air is heavier and you will get more boost than
when is warm. You have no fuel control and no fuel upgrades and no ECU tuning.
Be carefull!

I know! I will be buying the boost gauge this week definitely!
