Around 25K miles i bought new oem plugs from tischer, installed and got a misfire right away.. sometimes it would misfire on coldstart, sometimes it wouldnt, but almost everytime it misfired. If it didnt the car ran rough during the coldstart and the exhaust popped. No CEL/SES etc. just when i read the codes myself the misfire codes were there.
So recently ive been keeping a eye on my coldstarts and misfire codes. Tried no E85, map 0, map 2 etc. to see if it would go away. IT DIDNT.
My coldtstart were horrible with misfires and exhaust popping.
Otherwise the car ran good and logs looked good. No codes etc besides coldstart.
So yesterday morning i decided to go back to the old plugs the car came with (i had them labeled for each cylinder)
threw them in and cold started like a dream, no misfires, no popping.
So i took her out for a run and i noticed got a lil more power and lil more boost aswell. wierd. But the car felt great.
2 more coldstarts to verify the old plugs are working better then the old and i can gladly say my old 25K miles plugs do not misfire on coldstart!!!
No popping of the exhaust, no shaking and etc. new plugs have about a 500-1000 miles on them maybe. Misfires happened oon 1, 3,4 and sometimes 6.
Im guessing with new plugs, looks like def have to reset adaptions of the ECU or something. I tried disconnecting the battery aswell nothing helped.
Gonna run my plugs the car came with until they start dying on me for now. Until i feel like messing with resetting adaptions with the new plugs.
Yes i Tq'd them to spec down and uninstalled and installed them twice to verify correct install. They arent damaged and all the new plugs looked good after running them. Has to be a ECU reset of some sort only thing i can think of.
