check engine light
my 07 ranger xlt check engine light wont go off. im not sure what is causing
it. took it to auto zone and they said spark plug 3 was bad. my husband
replaced all the spark plugs and plug wires. the check engine light went off
for a day and now its back on. he rechecked for spark on all the plugs and
we got a blue spark on each. i bought a new gas filter today even though
it was replaced a couple months ago. we put gas treatment in it. i dont
know if i got bad gas or what is going on. any ideas?
It's possible you have a bad coil pack.
Also scan for the codes again and see if it is the same one. Could be a bad cylinder if the coil checks out.
