i posted a thread the other day about my CEL codes. egr.tps.iat.and o2heated.
well i replaced the o2 today, car seems to be a bit quicker, and throttle response is better, the car almost feels lighter. well after i drove it around for a while i came back and checked the CEL codes. I know only have 1 code, 10-Intake air temp sensor. lol the other codes are gone. does that usually happen? i know that when the o2 is cold the ecu has a pre set a/f ratio that runs rich until the car is warmer. but how hot does it get before the car is in closed loop. ive also read that when in open loop due to the rich fuel content the car is a little faster. well i didn't even have an o2 until today(previous owner cut it completely out) so i had to have been in open loop the whole time right? well when i dyno'd it the other day it made 142hp, and 125tq (its a jdm h22a by the way) and the power band was super shakey and topped out at 6500rpms.so if i was in open loop why was my car so sluggish, all info and opinions are thanked in advanced.
