Brand new throttle body put on about a year ago, checked all vac lines, map sensor,pvc, new 02 sensor. Sounds like extra air coming from somewhere. Suddenly louder than it normally is. Someone please help,
Not sure what this is supposed to be hooked up to or what it’s called just have it capped off for now .. 1990 k2500 by shane colvin posted Jun 24, 2020 at 8:03 PM
