Plug change now flashing ses Just relpaced all plugs and wires with msds and tr55s, took the ws6 out for a driveand as soon as she warmed up i could feel the missfire, ses came on steady andi went to drive to advance to get the code read, the ses started blinking, turned round and went home.
Checked all wires and they were all clicked in, gona get the lend of a scan tool tomorrow and see what it says,
Im so bummed, any ideas of what i may be looking at?
I gapped the plugs using the simple disk like gapper to close enough .55. Could i have applied too much dieelectric grease?
One other thing i dumped abottle of tectron injector cleaner into her and fill it to the neck till i couldnt get another drop in, could this have caused it?
Any help greatly appreiacted

New defective spark plug? I'd pull and inspect them....worst case, replace them again and see if that cures it. Could also be a defective new plug wire....
Filling it to the neck could also be causing fuel to be pulled through the evap?

The thoughts of doing all this again is horrible!!!!!
I also changed my pcv valve and didnt do a pcm reset, but it idled fine on start up.
The miss fire was only noticable on full warm up, and started after i hit her hard from a stop and heard backfire, ran shitty after that

Scan the car and determine which cylinder... It's been said three times now.
My guess is a bad plug. And .55 is a fairly big gap IMO but to each his own. A colder plug/TR6?? plugs might hold up better as well should the problem repeat its self down the road.

Usually when people report MULTIPLE misfires right after a plug and/or wire change....they have spark plug wire(s) touching the metal piping of the exhaust manifolds or LT's. Make sure the spark plug wires are not touching anything AT ALL. That will cause misfires.
.050 is the best gap for any N/A pump gas LSx engine.......but .055 is fine too. Thats not the issue.

Ok gentlemen, i scanned the s.o.b p0301, took out number one plug, it was black as coal, put in a new one and shes flying now.
However i still have the pesky p0200 code pending- the whole reason i changed the plugs and wires initally , i ran some injector cleaning through the gas so im praying it might clear up

checked all injector harnesses,all tight and secure even checked the resistance af all, all good the p0200 only happens after a shutter in first or second gear, can feel it missing slightly.
if the injector cleaner dosent work ill have to remove fuel rails and injectoers and give them a good cleaning

I am having the same exact problem. I also purchased my NGKTR55 plugs and MSD wires from Nasty Performance.
I am also getting flashing SES and code p0300. It will not tell me which cylinder is misfiring, just says multiple randoms when I have the code scanned. One p0300, another "pending" p0300
If you figure it out, check my thread I made-- exact same issue, same plugs/wires.
