Well, if nothing else, this has finally given me the impetus to get off my butt and re-wire all the electrical ---- from the battery to the engine compartment this weekend (Crossing fingers, hopefully nothing happens). I hate that tranny tunnel crap and have been consciously avoiding it.

i feel you. i wanna unhook the starter and untangle the wires around my clutch line and whatnot, but im so freaking lazy.

it's been suggested to me to run new grounds for my MS and i really dont want to. Like running 10 individual grounds to the head and back to my MS.

I may consider running new grounds to the MS while I am in there this weekend then, thanks for the tip Brainy.

Wow good lors blaen. You fail as hard as i do except you are circlejerkig the ever living shiz out of your car. I am just a fail mechanic and you are a fail spaz tryinf to fix everything that does not need fixing.

When you resume your compulsive convulsive assjacking do the followig

Turn off ALL
idle fuel trims
Idle timing trims
Idle air control bs

Also
Flash timing light and conform timing is correct after setting timing to 10*
Check the frikkn throttle cable
Check your frikken injector wire and cop wiring again. Yes i know you reqirs everything 3000 times but something gay like a loose wire or shhity joint could b causing you misery

Then


Richeb up the bitch
Open idle sxrew a bunch
See what happens

This very well could be MS fukkery but it is odd that your shi worked. Then failed again. Btw was there a BIG weather change between when the car worked and stopped working?

The IACV on the 1.8 doesn't work/is generally busted.

After that, your car will never run again.

Will do

Check the frikkn throttle cable
A FM cable bracket is in the mail.

Check your frikken injector wire and cop wiring again. Yes i know you reqirs everything 3000 times but something gay like a loose wire or shhity joint could b causing you misery
How about I swap it back to the stock wiring, Faefae? Because that has the same behavior - it takes me a few hours to get everything swapped back, granted, but I can. And it still has the same behavior as with the new wiring. So either my stock wiring and my new wiring has the exact same problem, and a multimeter fails to find problems in either, and inspection from both myself, one of the best mechanics I know, and a very good EE-guy fail to find anything or it's something unrelated to wiring.

I'll definitely try that when I get a chance, thanks Faefae.

The only change is spark plugs, Fae. Back to back, NGK BRK6E work well enough, Autolite XS3922 fail hard. All I have to do is switch spark plugs, and the behavior is repeated.

I have no doubt there is some underlying issue based on what Brainy has said. However, this gives me an excellent opportunity to fix all sorts of ---- I've been meaning to.

Care to lay a wager on that Faefae? Something akin to the wager the Hustly and I have going, perhaps?

Fine you win you are the wiremeister but I really don't understand all your troubleshooting methods make me dizzy.

So the NGK work? Autolite not work. Why not just run NGK then?

Because either I have a bad plug in the Autolite's, or the Autolite's uncovered something very bad.

If it's the first, it's easy to fix. If it's the latter, it's much harder, especially since the underlying symptoms are implying that it is an issue I've had since I first put the Megasquirt in the Miata.

I don't understand.

Why not just run another 6-speed on your Miata!!!!!!!!!1

Sure, I could have it run "good enough". That'd be no problem. Sure, it might last for days, weeks, months, or even years. But I'm not trying to have a "good enough" car, that's for a DD.

GREAT NEWS, MY WONDROUS COMRADES!

IT IS DONE! It actually works correctly once everything listed was complete!!

Cause? The .msq settings that Brainy told me to change from his basemap Brainy

But ----, I've gotten so much that I've wanted done on this car this weekend. It's driveable, WITH BOOST, now!

P.S. Brainy
P.P.S. I'm actually getting the high idle you described now Brainy.
P.P.P.S. All of my rough idle, vibration, etc. problems? FIXED. They don't exist anymore.
