Hi, Guys
I have cleaned up 2 O2 sensors with NTK, great for 2 months, but always had a slightly
rough idle. 4.0 CI
on the highway my Tj started acting up Bank 2 Senor1, used NTK cleared up ran fine.
seems now it runs different each time I start it.
Seeing all Jerry’s great info I realized I had the wrong plugs, so I changed to Autolight xp985
unfortunately I also added a little octane booster and sprayEd gum out to Tbody and IAC.
should of just done plugs. Now Changed 3 things.
Jeep drove better than ever, though slight rough idle still there as alway.
now I drive 3 time ran great, next day my problems are back,still popping thru intake if step on gas.
Put 89;octane gas no change.
Got Long Term Fuel Trim Bank 2 low
Pull and clean IAC real good, spray seat also, ran at idle spray 1/4 can
After clean Code P505
Code P505 will not clear now
Still runs like shit popping slightl.
In morning getting new gasket for TB and do a better clean.
any thoughts
Bought a BlueDriver code reader.
Thanks
Steve
