CEL after adding STP cleaner. What gives?
Hey guys,
So after I filled up tonight I added a bottle of the STP Fuel System Cleaner (can't get Techron in my area). I get about 1-2 miles down the road and my Check Engine Light comes on. I haven't checked the code yet.
Did the STP trip it? Did it knock something (debris?) loose in the engine? What gives?
My truck is a '99 V6 4runner (4x4) w/100k on it.

I'll almost guarantee that you fouled out your older spark plugs! Trust me I did the same thing with techron, change your older plugs ( 30K max plugs) and you'll have no issues what so ever....
NOW HOW'S that for going out on a limb....?

how about a loose gas cap? that wil throw a code, have to make sure it clicks three or more times.
Just filled up, there is no way the cleaner made it through the whole system in 1-2 miles, and even then the cleaner is so diluted.
