Hey guys, I've been fighting an idle issue on my truck, 93 K1500 350.
It started after I went through some deep puddles with my son.
Now once it warms up, it idles like crap and has died a couple times in traffic.
What I've done so far is replace the cap and rotor, plugs, wires, cleaned the EGR valve.
The EGR cleaning was by recommendation of a mechanic friend just based on what I've told him.
The cleaning worked for about a day, then it started again.
Where should I go from here?
Also, should my throttle body be making a constant almost grinding sound? Like a winding clock.
Also, how necessary is this black tube?
