I just had a guy come in.....check engine light on, 6 codes!
Evap circuit code. It came back but nothing to do with the complaint.
Cyl 4,5 misfire. Didn't come back on but after the replacement of the plugs the engine smoothed out.
3 different 02 sensor codes that meant nothing
I charged him 100 for the plugs and didn't wait until it cooled off.
Of course, if you had spent an extra 1000 for me to tow it to my shop I would have fixed it for free, cause, we like you!
