Check engine light on after Lucas Injector cleaner

[yooh_munkee]

Hey guys,

I recently decided to clean my fuel injectors in my s14 with Lucas after hearing reviews that it was pretty good. Emptied the bottle in and then filled my tank back up with premium. I drove it for about 30 miles and then my check engine light came on. Went to check it out and it says knock sensor is bad.

I never had any problems before the Lucas and even though it says knock sensor is bad I don't have any problems with driving. Response is the same as always, if not even better. So I was wondering if the Lucas could have set off the sensor to trigger the check engine light?

Been driving it for a while and even refilled a full tank with premium but light still hasn't turned off. Do y'all think it really could be the knock sensor failing or a false code? Should I just reset the code and see what if it pops back up?

Almost all fuel injector cleaner causes slight detonation (usually not audible or.damaging) and can throw a cel. Since you have already filled the tank, id say clear the code and check for codes next fill up. Most likely the code won't come back.

Instead of using gorilla snot like Lucas, use a fuel system cleaner containing PEA (polyether amines) which is proven to clean effectively without leaving its own deposits behind. Chevron Techron, Redline SI-1, and Gumout Regane all contain PEA.

Had a car that sat for a year, put seafoam in and it started right up and cleaned the gas. I love seafoam
