Strange, “Pop, pop, pop…” sound from intake manifold
94 FZJ80
When I advance the throttle from idle I hear a, “pop, pop, pop…” sound coming from the intake manifold, I think. The noise has become progressively louder during the past week. The noise is only present during accelerations, once a desired RPM is selected the sound stops and the truck seems to continue running fine. No notice in power loss.
Any theories or solutions for a fix would be greatly appreciated.
