Hey guys so i finally got my headers on my truck today. Have some questions about the Doug Thorley Long Tubes...
1- My engine used to idle at 7-800 rpm, now it idles a bit lower like 5-600 rpm. Is that normal due to the cats being eliminated?
2- My check engine light is on as well as my slip indicator, duh (its the o2's right?) But i have a urd o2 simulator hooked up correctly to my truck. Called Gadget twice on this one. Ive reset the truck three times already and its still showing up after about 30 seconds. Any ideas?
Note: The error code it P0053 HO2S Heater Resistance (Bank 1, Sensor 1)
But wtf does that mean???
Any help would be appreciated. Im gona have my buddy at Toyota look at it tomorrow for me too but any additional thoughts would be grrreat.
