Well crap...
My car ain't running right. I made a boosted pull through second and it spun the tires. I let off. Then made another pull and it didn't spin, but I looked in the rear-view mirror and I see black smoke, like it's got a miss. Sure enough, it does. At idle and I can hear it has an intermittent miss and it doesn't have the power it should in boost, and it's smoking in boost. Like it's running on 3 1/2 cylinders in boost. Fuckkkkkkk. I'm gonna pull the plugs in a few, letting it cool down a bit. 
I hope it's nothing serious. Yeah, right....

Well, I went for another ride to get some new plugs so I could change them. Now it's running fine and no smoke... No idea. But before I left I noticed one of the manifold studs backed out of the head and it's leaking pretty bad. Haven't fixed that yet.
So perhaps the exhaust leak is the problem, or part of the problem. I've been smelling exhaust the last few days and I was certain my external wastegate broke from where it was brazed on the manifold. But thankfully, it's fine! No idea why a manifold stud backed out though, but hopefully that's what's making it spool slower. Still don't see how that could make it smoke out the exhaust though.

BTW, how is your oil consumption? Not that I know **** about the subject but in my case, that was how I first realized I had a problem.

Yeah, fingers crossed it's nothing major. It did something similar before when I was N/A after beating on it one day and a new set of plugs fixed it, though the old ones looked fine... I dunno.
As for oil consumption, it doesn't use any oil whatsoever. Before I turbo'd it I would go ~15K on an oil change and it would be low by ~4 oz, of which I recently discovered was leaking out of the seal in the back of the head where a CAS would go. Fixed that when I had the motor out. So far, it hasn't used a drop since I turbo'd it.

Pulled the plugs and they look fine. Carboned up from running rich, but otherwise appear great with no signs of detonation. Tightened that loose stud up and it's a lot quieter now. 
Hopefully everything is fine, though I still don't know why it would go to missing on one cylinder like that. Guess it wanted some attention...
My PCV and crankcase both just dump to atmosphere, so that's not it.
My camera skillz suck. And I was using the flower.

Well... Started running pretty bad today. Right after a boosted pull it got a miss at idle. Which turned in to a miss at any RPM. Got home and the motor is "chugging" at idle, running like pure ****. Then it starts running perfect. Then back to ****. Well, I'm pretty sure it's ignition related now. Thank god. I'm also seeing a trend. It only runs like **** when hot... IE-yesterday when it started this ****, it was after a long drive and then a boosted pull. But after I let it cool for ~ an hour and changed the plugs, it was 'fixed' till it got hot again today.
I hook up the computer and datalog it idling. Got a solid RPM reading, fuel is smooth, map is smooth, etc. AFR's are all over the place because the motor is missing. Yeap, 99% sure this is a not-sparking problem, not a blown HG, etc. Besides, plugs looked good yesterday.
So I pop the hood and make sure the sparkplug wires are snapped on tight. Good. I wiggle some wires, nothing changes. Still missing. Then I put my hand on the EDIS ignition module. Hot as FUUUCCCKKK. Swap it out for my spare that's "bad" and it runs 22.4 times better. No miss at idle whatsoever, drives smooth, but it gets a slight miss at higher RPMs when cruising. (I called this my "bad" module because when I ran on it, I had a miss at cruise. No surprise it still does). So I'm now 100% sure I have two bad ignition modules.
So anybody wanna post a link to a CHEAP new one or a steal on a used one, let me know. I just scoured ebay and a used one is ~33 shipped but it's not tested to be good. Might just buy a new one cause this is getting old.
They put these on 91-96 Ford Escort w/ 1.9L and the Mercury Tracer 91-whatever w/ 1.9L.

:j erkit:Is your ignition module different than the ones on 96 cars? If not, shoot me a pm. I've got a spare I bought and never used.

Yeah, the module is different. It's from a Ford Escort. I retrofitted this ignition system onto my 99' because it was supposedly cheap/easy/relaible/simple to install.

I even have the COPs, but I don't know how I'd wire them up. Actually, I need to ship JasonC SBB a COP to test to figure out optimal dwell. It would be a pain in the *** to get MS setup to read the trigger wheel directly, and fire the new COPs. I'm sure it sounds easy, but I can't have the car down to 'try' to figure it out. No other vehicle to drive right now.

FWIW; the only mod I can claim credit for doing on my own to my car was the COP setup.
Isn't Chad using COPs?

Yeah Chad's using Toyota COPs. I sold him two of them.
The problem is I'm a dumbass and put weird, odd ball stuff on my car. So I have to reinvent the wheel every time I want to do something. This summer I'll change it so that MS reads the trigger wheel directly and fires some COPs. For now, I just need to put a new ignition module on it.
I drove it again and WOW is it smooth. Apparently some of smoothness/driveability was lost in that dying ignition module. Granted the one I'm using isn't perfect, but it's a lot better. Guess I'm gonna order a new one...
