On the cold days it is hard to get full horsepower and torque out of engine. Under load it is hard to get it up over 3000 rpm. Is it the alda? Is it one of the lines running to the alda leaking more when it gets cold or something else?
I suppose I could remove the alda but I don't want to take that step unless it makes sense.

Retired: 95 E320 157K miles and currently parked with blown engine

Both retired cars are for sale as is my w124 shop inventory

If it pulls good rpm's in park but not under load I start with filters first; then make certain it can breath.
