After I drive a little basically after it’s warm if I drive it not like I stole it but not like my grandparents either usually while I’m in the accelerator and I can get it to go off for a few miles just by letting up in the pedal but it doesn’t stay on if I stop and try to check it at a garage decided to buy a reader to see if I can at least get a read on it Any thoughts before I get an attempt to read it
