Becky Posted May 23, 2020 Report Share Posted May 23, 2020 Becky purchased this 09, GT500, she loves it, meanwhile, I am trying to get it mechanical up to date. There is a check engine light, the code reader says the O2 sensor is bad, so they were replaced. The check engine light still comes on. Ford, says because the previous owner installed long tube headers, they are seeing the exhaust temperature is to low????????????? and that is connected to the O2 sensor alarm. Everything runs great and when myself and Ford look at the data, the engine is doing well. So Ford said that I need to contact Shelby, and ask them. Oh well, I called and no one answered, who knows if the office is closed just for now. Any ideas??????????????? Thanks in advance, James, Beckys' mechanic.

Secondo Posted May 28, 2020 Report Share Posted May 28, 2020 Contact a reputable tuner for the fix. AED, Lund, VMP, etc for example. Quote Link to comment Share on other sites More sharing options...

Gerry Chase 1128 Posted January 31, 2022 Report Share Posted January 31, 2022 Use on the downstream 02 sensor bung. Most tuners won’t shut it off. https://www.355nation.net/threads/how-to-install-an-o2-sensor-non-fouler-to-eliminate-a-check-engine-light-with-pics.401/ Quote Link to comment Share on other sites More sharing options...
