I have been having weird noises from my after market intake I have had it on for 6 months and just randomly it started vibrating and making a humming noise! Cant figure it out I replaced my ICA and made brackets to try and suport it better. It still does it. And just recently my heating will stop flowing threw the vents when I get up to around 55 going down the road for a little ways than when I let off the gas It starts flowing again I believe its a vaccum leak? What do you guys think????
vacuum leak. with it running spray carb cleaner around all vac lines and gaskets, when the engine stumbles, u found your leak. u should also have P0171 and P0174 lean codes
I sprayed the line with carb cleaner and couldnt find anything Im getting my friend to hook a smoke machine up to my truck to see if I can find it what do you mean by lean codes?
