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

Coil sticks can be finicky. Are you sure they are pressed down completely? Push hard. If that doesn't work - I would put one coil back and see if that cylinder's code clears. I have a feeling you may have either the wrong coils, or some bad ones.
thank you so much for your insights
I did exactly what you said and problem codes are fine car is driving smooth again

i must have not pressed down hard enough on the back ones and just relied on the screw to secure them in place.

i really appreciate your time to respond
