To all you uber experts:

I dug up three MPS's from the crate and tested them

1) 043 MPS. Lost 6 inches Hg over 5 minutes. Tested at 91 and 338 ohms.

2) 049 MPS. Lost 4 inches Hg over 5 minutes. Tested at 89.7 and 328 ohms.

3) 043 MPS. Would not pull any vacuum, toast.

...

So, is #1 any good? If not, can I use the 049 on a 2.0L?

Thanks!

NO

At idle the engine vacuum (15hg) will overcome any leak down unless its blown. It has to be a pretty good leaker to effect the mix much, mostly it just effects transion from cruise to idle or off idle to cruise. The response just isn't crisp like it should be.

Okay. Then it sounds like it's even less of a problem. idle/cruise transition isn't my chief concern. If part-to-full throttle transitions aren't badly impacted, then I don't think I care too much. The car will spend very little of it's life (from now on) at cruise throttle...

Thanks for the info!!
