Could Spark plugs cause "Reduced engine power"

hankock · 07-29-2012, 04:43 PM

I am asking does anyone know if bad spark plugs could cause a "engine malfunction reduced power" warning.

i was thinking yes if its misfiring but shouldn't that be a check light, all info is greatly appreciated and needed. Thank you

Absolutely. I would scan for codes if you are getting the warning so you can know what cylinder may be misfiring, and diagnose accordingly.

INPA can read codes. Get it working on a laptop
