I drove my 2005 Chevy Equinox 20 miles at a
hundred miles per hour now when I got home the
truck died in the morning I hooked up the OBD
reading P0300 and the check engine light is
flashing the truck used to run perfect it has a lot of
miles over 200,000
100mph for 12 minutes doesn’t seem like enough to do any mechanical damage. Did it overheat? Have you tried clearing codes to see if it returns?
Where can you drive that fast, that far and not get pulled over?
@F.O.R>Manteca to modesto only in california @Js08016>the car was already trading a emissions code before the misfire. I just replaced the spark plugs and spark plug wires, oil change, radiator flush and air filter a week before the incident. I can only think of the injections or catalytic converter itself is clogged. Is there anything else you can think of besides a tune up.
