Having a power issue with it, feels very sluggish. No check engine light. took it to my mechanic, electronics are all good. Fuel and spark are good. But did a smoke test and checked for vacuum leaks, found 2, one is that thick hose under the upper plenum, the 2nd is where the lower plenum mates with the block. Tech thinks that bcc of those intake leaks. The engine isnt getting enough air to all the cylinders.
When its warmed up that is...idle seems fine, only other symptoms are a slight hesitation on accel when the engine is cold. Like its about to stall, and the engine sounds a bit louder than normal
