header leakage/replaced idle question
Names hunter im New to the forum (dont judge me I havnt paid the 19.99 yet) never really planned on being a jeep person but... it happened. I have a 99 wrangler sahara 4.0 with the ax-15 5 speed, small unkown lift with 33" bfg takos, big dry rotted 35 mud tire spare on the swingarm that does wonders against idiots that dont stop fast enough. Anyways Ive had a header leak a while now had it welded up by a buddy, 2 weeks later it found a way out again. Severed the pipe in half where the first 3 cyls collect into the Y. Anywho ordered a borla header... I read somewhere on here to go with a cheap replacement but im stubborn and loved the borla exhaust on my sc300. Im not 100% on the part no. But it was the only borla header off summit. Soooo... the FIRST time we pulled it apart to replace it I guess I missed the dowels on the head that lines up the intake and had it screaming at "WOT" so we tore it back down to hopefully install it correctly. Now I used to idle around 650 700 now it idles around 1200. Other than that it drives like a ****ing dream.. no other way to put it.. its insanely different. I can shift it at 4000 without worrying about it exploding.. so what ive done so far... I unplugged the battery 30 mins or so and made sure all my vac lines were hooked up... I plan to spray some aerosol tb cleaner in the iac motor hole later any suggestions? Ill get some pics up

Have you looked into replacing your exhaust manifold with the 2000+ style 2 piece manifold and an aftermarket "Y" pipe (or a "Y" pipe made at an exhaust shop)... HTH
Idle spec is 750 +- 50 rpm and computer controlled. 1200 rpm may be the result of a small air leak.

Ok after looking it over maby my ac not worki g has something to do with it.. the small vac hose that connects to the side of the intake that runs across the bulkhead towards the battery. I believe its for the blend door switch... that hose is severedafter the T by the battery
I didnt call the guy a cock sucker because I didnt like his comment. My response to his comment was sarcastic at best. You clearly dont have anything worth a **** to say but thank you for what little input you have given me. However irrelevent it was to my questions.
