So, my car was at the dealer today, I disconnected my access port but left the green connectors in the fuse box collected, but not under the pas side carpet. First thing they noticed. Asked me about aftermarket computer blah blah, I denied it. so they disconnected them and the CEL came back on, PO203 cyl 2 misfire. They found it had a bad coil, and that plug was loose, he said the washer wasn't even crushed. Also found my colder plugs but the tech said they were hotter? I just want to make sure I got the right ones now, LFR7AIX one step colder correct? So they wanted to put in the stock ones, $250 I said no I'll do it myself. Hopefully thats it now. Coil was covered by my extended warranty, but he said if I have problems in the future with the wrong plugs they may deny me, whatever.
