Exactly what he said. These are just headers not rocket science. I was very careful on the removal and install of the O2 sensors. I even put them in zip lock bags marked from what engine bank and order. I never let anything touch the O2's either. I checked and double checked all my connections. Installed new plugs and gave a couple of days for the PCM to "relearn". Since you SHOULD disconnect the battery during a header install. Car ran odd for a day or 2 but after that it was music to the ears and a awesome seat of the pants feel. No codes at all.

 

okay, i am going to try this fix. my car was running just fine before though, does some how putting on headers ruin the old plugs??? i don't get that, but i am sure i could use new plugs anyways....

 

 

LS1Sounds and LS1LT1 answered that question up one post.
**** happens, and sparks can get damaged or gap set off.
ngk tr55s (one the of best spark for ur ls1) are 1.89(times 8). its the cheapest insurance ever. also u can adjust ur gap. the plugs come at .050(instead of the .060), which some recommend for a bolt on setup (see www.ls1.com)

 

thanks, hopefully that fixes it...

 

That's not the problem, as long as you're not using the HPP Power Tuning, those others parameters/settings shouldn't be related to this particular problem IMO.

 

get to a dyno and check your A/F then have someone tune the car correctly and delete the rear O2's, you will get a SES light if you dont have O2simms or delete them.

 

car is running like a champion!

it was the plugs....

 

 

ditto!!!!!!!!!!!!!!!!
sparks win!

 

hahahahahhaha....merry christmas

 

what should I gap My tr55s at For NA, and what should I gap them on for Gas. I have 38 degrees of total timing right now.any thoughts would be appreciated=)
