For the F20B and H22 swaps... HELP
I had a ulev in before the swap and I am having the worst time with my idle once it warms up... it idles down really low and sometimes stalls when i rev it up while idling or coming to a stop at a stop sign. I have research so many different forums and it seems like there is a lot of people who have this problem but no one even gives me a solution to the problem that i havent already tried. I have a CEL and the code im getting from the CEL flash test is
41 P0135 Front HO2S Heater Circuit Fault (Sensor 1)
41 P1166 Primary HO2S (No. 1) Heater System Electrical
41 P1167 Primary HO2S (No. 1) Heater System
I put a brand new front O2 sensor from an F23A1 and its still throwing a code, then i added 1 and 2 spark plug defusers and still had the code.... finally i pluged the hole and let the O2 hang with still getting a code... im hoping this is why my idle is why it is but i have to get the code to go away to see if it is.... any suggestions?! also im running DC Header w/ downpipe with a test pipe back to 2 1/4 back to a Greddy muffler if that matters... PLEASE HELP!!!
