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! -Josh2 |

If the leak is slow, I would think that the longer it idles the richer it will get. Does that sound right? If that's the case, then I would have a justifiable reason for revving the motor at a stop light (or staging line) right?
Max vacuum will be closed throttle at high rpms, which never lasts long. So that wouldn't be the big concern, but minutes at idle would definitely make it run richer and richer if I'm thinking about this properly right? I guess my question is this: Will I harm the motor (the bigger investment right now) by running the stock FI with this MPS for a year or two of track/autox events? -Josh2 |
