Remember your other posts - so the fuse is OK and you found the problem? After my Vig install my idle would "hunt" at low speeds while coming to a stop or going into reverse while parking. I got a tune to increase the in gear idle, line pressure, remove torque management, etc.
yea i remember the other post but know the fuse i quess keeps blowing ever after i just replace it....ive checked the o2s and the lines look ok to mee no breaks or anything....i think the maf might went out???

You've got to find the reason the fuse keeps blowing, still think it's an 02 harness, or something else on that circuit, short caused by something the tranny shop did when they installed your TC. Have you contacted them about it? I'd ask them to put the car on the lift and look around. Just started after they worked on the car right? Visit gearchatter.com and look up the diagnostics for 102, 135 and 155 - might find something there, but all the diagnostic charts for those codes say check the fuse. Hang in there, sure you're frustrated.

Get them to put it on a lift for you and check them before buying anything. All it takes is for an 02 harness to arc on a LT somewhere or pinch it between the housing and it'll fry the ENG SEN fuse.
well i looked al under the car for a broke wire on the o2 extensions but couldnt find one but the drive side o2 right before the plug was melted so i went head and swapped them out.... so hopefully that will take care of that i hope... but car through a new one... which i made a new thread about thanks man!!
