Need assistance cleaning intake manifold runner that is stuck open
Where should I begin?I've changed all plugs, cables,cleanened egr valve, and iac+outerside of throttle body(in front of flap)z (was told not to touch on inside of flap since it has a lubricant that cannot be removed?). I also sprayed the maf with maf sensor cleaner a few times and did not touch fibers on inside cause Ive also been told not to touch them since they are fragile few times.-Not sure if that was actually sufficiently. After all of that My truck still surged of control and stalls constantly when in low gear or idle as well as while in drive when gas is not being applied. I know this is alot of questions but I would greatly appreciate any help or direction as of where I should start first. Thank you
