Hey everyone,
I went to go get my DeLorean smogged last weekend and it failed the 15 mph NO test. It measured 1269 aand the max is 1148. In the 25mph test it measured 935 with a max of 978. The tech recommended that the O2 sensor be replaced but that was already done about 2 years ago. I took it for a good drive before the test to get it nice and warm. Any thoughs on what could be causing the issue or how to get it to pass. 2 years ago I had the engine tuned up at DMC california and haven't noticed any issues with it. Thanks in advance! 0011_001.jpg
