Hi Everyone,

hoping someone can please help me. Our palisade is just shy of 60k miles and as part of routine maintenance just replaced the ignition coils and spark plugs.

All seemed fine and straight forward

then proceeded to use the CRC GDI injector cleaner

Turned off the car ready to test drive and the 3 codes came up P0201. P0203, P0205.

pointing to the back cylinders.

i used the ignition coils and spark plug kit from 1A Auto.

not sure what went wrong. Should i put back one of the OEM ingition coils back and retest?

any advice or guidance would be much appreciated

thx

My thought on the matter is "Never fix something that isn't broke." You stated "as part of routine maintenance" nothing you per did was routine. Switch to TOP TIER fuel and only do injector cleaning if there is a problem. TOP TIER - High-quality Fuel Performance Standard - TOP TIER™ (toptiergas.com) Hyundia recommends top tier fuel and it is not available ad a detergent to the gas tank at each oil change.
