Just changed spark plug on my truck day
later cel came on. Press on gas pedal and
then the truck starts to slow down on its
own. light still on wasting lots of gas
Changed the pcv not the oxygen censors
Gas cap must be tight~
Gas cap is ok Eco doesn't come on at a steady idol
runnin' rich...suspect your thermo-time switch may be at fault~
but the oxygen sensor is a sure bet....pull it out and see how much of the platinum surface remains...if not done....like 90 percent of the time~ you could plug a scanner into your OBD-II and it will tell US what the deal is~
or just use the force, OBI!~
Jajajaja I wish May the force be with you!!!
