I decided to "test' my ALDA with vacuum this evening before reading this post. Uh-oh did i damage the ALDA by pulling a vacuum on it? i noticed something odd which at the time i ignored. the first time I pumped the Mityvac i noticed it held a vacuum. then i pumped it down some more and now it wont hold any vacuum. Did i bust it? Will test drive it tomorrow.
I read an article (
ALDA REPAIR ) that suggested testing it with a mityvac, which is why i did this.
I only have one complaint about my car's performance since i bought it a year ago. The pickup is sluggish at low RPMs when cold particularly up a hill but when warmed up it's good. I've already cleaned (didn't need it) the banjo bolt, both fuel filters are new, valve adjusted OK, overboost protection was bypassed by previous owner (one day I'll restore this).
For some reason i can't post a picture (the attach file and browse box don't appear) in this message. Instead you can see my ALDA by going to this other post of mine. Someone in that post commented that i had a "virgin ALDA" .
