Hello Everyone,
I have given my brother my old truck to drive for the winter, which is a 2000 Chevy 1500 4x4, it is a 5.3L 327. When I purchased the truck from the previous owner, he installed 02 sensor cheaters...which I believe just send the computer a signal saying hey....everything looks good down here...keep putting in "X" amount of fuel. I believe that these cheaters are now beginning to become pieces of $hit. There are 3 codes currently being displayed; P0135, P0140, P0158. Which are all 02 Sensor related errors. What i'm wondering about, is there any easy way of getting rid of these or tuning them out? Would I have to go into the tuning and basically make it run in open loop all the time and force a predetermined value in the Fueling Maps sort of thing? I should also add that this truck has the CAT's Removed, so there are no downstream 02 sensors...I will have to crawl under the truck when I get a chance here and double check.
Thank you,
Jordan.
