    Misfire was due to dirty O2 sensors. I ran it at 4000rpm for a few minutes and now it runs great! I have ordered a new set of sensors, as over 305,000kms and they have never been changed. Sorry to get off topic, but I wanted to confirm that my clone Tech2 works great to solve the ethanol sensor reset.Yay!

    I got my Tech2 clone today. It took me a while to figure it out, but I did find the alcohol content reset setting eventually. It was reading 27% and reset took it to 3%. It's still misfiring, so hopefully it only needs a few key cycles and some driving to correct. But my mechanic's reset a couple months ago (was reading 37% and reading brought it to 3%) worked almost instantly. So it remains to be seen if my $600CDN investment was a waste of money or not. pulse widths are 2.0ms bank 1 and 1.8ms bank2

    No, I don't know those things. Why do you mention them? So I should have some luck with a tech2 clone? I am driving a 2007 5.3L Vortec Suburban

    I am also having trouble with my fuel trim cell getting stuck at a high ethanol content, causing dumping of fuel into the engine and causing misfires. It happens almost everytime I fill. I am aware of the fueling procedure to avoid this issue, but getting the procedure can be difficult in a cold climate like mine, so looking to be able to reset the sensor when this happens. Following, and hoping someone can recommend an inexpensive scan tool that will do the job, as my research reveals that descriptions of scan tools are very vague and don't seem to show their full, detailed, capabilities.
