Low Idle Vacuum
The sort-of new 2.7 runs OK (except for the oil leaks).
I have some reground Solex grind cams in the engine. I have low vacuum at idle, no air leaks. Once it gets to 2000 RPM, the vacuum is fine. I am guessing cam overlap? The engine is single plug, 9.6:1 JE pistons, stock 2.7 heads. TIA Pat |
Check the static timing and full advance .

EFI. I dialed in the static everywhere from 4-10 BTDC. Full advance doesn't matter at idle.
