Well, that didn't do it.
But now I have reason to read the electrical diagram for a minute before I go through the trouble of pulling the alternator belt. |
sorry...
wow though... i've learned more in the last hour in the fsm than i have in weeks here.... i know how i'm gonna spend time in honduras :) |
The FSM gives remarkable insight - if you have the patience.
I've read it like a novel. |
Yeah - EVAP, MOP and JAB are all on valves, but the flow positively.
I blocked the EVAP entirely at one point, but that did nothing. |
Y. Sry.
I txt w/ acro. (Yeah. Sorry. I speak in acronyms.) |
That's for sure.
Actually, that is probably part of the problem here. I haven't really been able to think linearly on this one - I get side-tracked. I am going to go try running the car with the alternator wire disconnected and then the battery disconnected and see what happens. |
Is it the Fourth of July already?
|
So, you want to celebrate by setting my car on fire?

take the tps off and crank the car and take a vacuum reading. if your vacuum is in the normal range then you have eliminated one system.

my car has a vacuum reading of 15hg at idle too so I will be paying attention to this thread.

olddragger We don't have one. You mean disconnect the throttle completely? What will that do? |
It might (I suppose in theory), except no one else that is running this setup has lowered idle vacuum.
Really, if the turbine was restricting exhaust flow at only 6 g/sec, the car would stop running at WOT before I got to 4000 RPM. |

Maybe take a step back and list all the things that affect idle vaccum and walk through them 1 by 1.
Intake leaks Intake restrictions air density rotor sealing AC load Alternator load water pump oil pump Idle RPM What else? |
The motor read this way out-of-the box with only 47 miles on it.
I already did the OMP jacking to maximum (the Mazda check for compression/vacuum loss) and it made no difference. |
throttle not closing right
|
Plus, the idle speed would go up.

Something sucks under your hood.

That which is obvious need not be discussed, thus I didn't bother mentioning it.

Small hole in your wastegate actuator?? Solenoid?
Are your fuel trims normal at idle? Something that transferred with 2 different engines right.... Did you figure out the High amperage draw? |
WG actuator is cut off from its vacuum/boost source at idle by the solenoid.
The problem followed two motors. I didn't discover where the draw was. It started raining before I got a chance to play. Fuel trims are rock-steady 0/0. |
Brake booster??
|
Plugged it. No difference.
Same with EVAP, OMP and JAB. |

Doesn't this suggest there is no leak, otherwise trim would be stepping in? If so... You've sort of ruled out engine seals. New engine rules out port problem. What's left? |
