My buddy has a 1998 5.7 Volvo 5.7 GS with an Edelbrock mid rise, and an 850 double pumper. (this was the engine that ingested water due to dieseling)
The ingestion issue has gone away, but after idling thru a no-wake zone after about 5 or 7 minutes, the engine, on its own, will start to increase idle rpms all by itself, without touching the throttle.
There is no vacumm lines to leak, becuase the Holley 850 has mechanical secondaries, if there was a manifold or car base leak, the engine would not idel well at all.
My theory is this:
Since the double pumper keeps the secondary bowls full at all times, even at idle, Could a float be sticking to the point its starts to dribble fuel into the intake? thereby increasing engine rpm without any advance on the throttle?
When the engine is shut down, it diesels, but not to the point of water ingestion.
Am I on the tright track? or am I all wet?
Again, this engine had none of these symptoms last year, it ran great with no issues.
So I don't see how the timing could effect it,
One last thing guys, can somebody please tell me what adjusting the "dizzy" is?
