Spark plugs

[WildHorse]

The LTR6IX-11 are gapped 11mm (.043) from NGK

Those have a 1" reach, mine are 0.984", a .016" difference.

I'd need to height gauge the plug reach. .016" could be +/- production tolerance range.

Don't be SKEERD

I’m back after being gone for a bit, had some things to take care of but here’s an update:

I replaced the spark plugs and my misfire code is gone, when car starts it feels way better and all around smooth. The only code that is still showing is p0741 and p1744.

I haven’t been able to find any information on this and what the cause is and where the solenoid is even located. Any help is always appreciated.

Those are transmission codes.

Those are transmission codes.

Have you or anyone you know dealt with these codes? I honestly don’t know what step to take next in regards to this.

your converter clutch solenoid is fubar'ed. Usually tune related. And cause your tuned, good luck getting it warrantied I'm afraid to say. Do a KAM reset and cross ur fingers and toes it doesn't come back.
