I changed out the spark plugs with NGK Iridium, fired it up, had an engine miss, forgot to connect one plug, am now getting a PO355 code. Any ideas.
Thanx

P0355 means Ignition Coil E Primary/secondary circuit malfunction. good luck

I would check all the coil packs to see if they are on all the way.

The trail always looks easier from the top of the hill.

double check the packs to make sure they are plugged in all the way.

did you cycle the start up process a couple time to see if the code clears. you may need to do this so the computer sees there is no problem now that the pack is plugged in.

good luck

"did you cycle the start up process a couple time". I'm not sure what this means? Besides disconnecting the battery (and a scan tool) is there another way to clear the code. Thanks for all the replies. The vehicle runs and drives fine.
Aloha

if you corrected the problem (for sure), it will go away. if it bugs you go to autozone and ask them to clear it
