Help! Checked one spark plug...

[Vytasb]

I took off the coils on the passengers side, checked one spark plug, saw it was fine and put it everything back. Now I have 4 codes! P0353, P0357, P0351 and P0355.

All coils are seated correctly and the spark plug I put back was tightened down. What is happening?

This may correct itself after a few starts , if not then try to disconnect the battery terminals , touch them together for about 10 seconds then leave them disconnected for more than 10 minutes .
This soft reboots several modules within the vehicle .
Hope this helps [emoji1303]

I'll give that a shot and report back. Hopefully that works. Thanks!

These trucks are terribly sensitive electrically , keep this in mind as a general rule of thumb :

Prior to disconnecting anything electrical ( to include spark plugs coil packs ) just disconnect the Neg battery terminal as a step One ...just to be safe [emoji1303]
