Missing and stalling Reply #30 – May 16, 2012, 05:14:15 PM I probably have a spare coil you could try too if you want me to check. Quote Selected
Missing and stalling Reply #31 – May 16, 2012, 05:32:52 PM If you were closer than Offut, I'd consider that too, but we live about as far north as possible in Omaha (Ponca hills area), so it wouldn't be a quick drive. There's one at Oreilly's for $18 that should be good enough quality to let me know if it's the problem or not, and I think I'll get a new air and fuel filter while I'm there too. But again, thanks for the offer. I get the feeling that It'll be nice having a knowledgeable person in the area. Quote Selected
Missing and stalling Reply #32 – May 16, 2012, 11:44:21 PM Finally, some good news. I got the cheap coil, put it on, and immediately fixed the missing. Took it for a drive, and there was no cutting out, no stalling, no obvious missing. Progress!Though it still stumbles occasionally, most notably when you're cruising along and let off the throttle. It feels like the engine shuts off for a fraction of a second, and tends to make the car jerk. Other than that, it's got a slightly lopey idle and it still smells a bit rich. I'm guessing it's a fuel problem, probably gummed up injectors or a plugged fuel filter. But first things first: A victory beer. Huzzah! Quote Selected
Missing and stalling Reply #33 – May 17, 2012, 12:40:22 AM first thing I do with every car I buy is the fuel filter. I have never replaced one with even slightly clear fluid in it.My buddies thunderbird was losing fuel pressure, and it ended up being the fuel filter being rusted out. When we swapped it, black tar like came out and stained the ground. Ran a lot better, reved quicker. Mostly I have noticed a very slight increase in mileage per tank, and better throttle response. As far as I can tell it hasn't really effected power.Time for that h.o. swap now that you got it running good. Throw some newer/rebuilt 19#ers and h.o. cam. Quote Selected
Missing and stalling Reply #34 – May 17, 2012, 10:22:07 AM The previous owner said he changed the fuel filter, and while I'm sure he did, I'm not sure if it's still clean. After all, the car has sat for a long time, so it's still probably pulling up from the tank. Other than that, the injectors are probably a little gummed up. Of course, going for an HO swap would easily fix that... But I'm also considering just getting a Moates Quarterhorse and keeping the non-HO firing order. I'm not sure which way is better or easier or cheaper or more powerful, but I haven't planned that far ahead. Though, I do know my friend has some truck heads he'd be willing to part with and I already have the HO upper, so I have a source on some good parts already. Quote Selected
Missing and stalling Reply #35 – May 17, 2012, 01:06:50 PM Plugged fuel filters are a real ISSUE in my view but the engineers dont see it that way. And the new cars have them in the TANK. Happy DAYS. Drop the tank or remove the access plate to service. And the engineers claim they are lifetime filters. I have seen filters plugged to the HILT and some engines run fine for the most part. But i am in favor of regular fuel filter maintenance As stacks points out . +1Note a bad coil is not that common on fords TFI SYSTEM. Other than the aftermarket JUNK COILS BY MAJOR COMPANIES!!! Always use MOTORCRAFT OEM. But a quick run on the DYNE with the cylinder scope would have picked that up in a second. Also resistance readings are a waste of time when shooting coil issues. I know i will get push back from this statement. Also a poorly tuned TFI system plays havoc on these systems and takes it toll in TFI modules and components. The tune must be spot on or the system will eventually FAIL :burnout: Quote Selected

Best to use factory coil. Quote Selected
Missing and stalling Reply #37 – May 17, 2012, 07:10:06 PM Some 87's have plastic timing chain gears.Do the h.o. swap. I picked up an h.o. cam for $20 from a stang guy, upper for around $20, exhaust "headers" and an h-pipe for about $100, and the stang sd computer for about $50 if I remember right. This should get you from 150 hp, to about 225. Quote Selected
Missing and stalling Reply #38 – May 18, 2012, 10:54:40 AM Changed the fuel filter last night, I didn't see any crud come out of it when I let it run out, and it didn't really change how it runs. Oh well, cheap insurance. It sort of feels like there might be a dead spot in the TPS now. It only seems to cut out when I lift off the gas slowly, when I just drop my foot off of it, it'll slow down without any missing. Not sure if that could also be causing the rough idle too, but at least it's good enough to drive now. Also worth noting, it doesn't smell anywhere near as rich as it used to. Still a little bit rich, but I'll figure that out eventually. Also, last night I messed around with the clutch cable, I routed it beside the engine mount instead of under the k-member, and I also shot some rem-oil in it to help it slide freely, and it has made a world of difference. Before, it was stiff enough that my leg was actually sore after a day of driving. Now it feels very springy instead of grinding. Haystack, you're starting to talk me into doing the HO swap instead of the other way. I already have the HO upper, a free flowing H-pipe, Mustang HO style tube headers, and a source for the 87 and up style HO heads. I'd just have to find a speed density computer from '87.

Ya know, I'll take the injectors. Let me know what you want for them and shipping (Unless you're coming down to Omaha anytime soon... Or, I guess we have a trip to Owatonna next month... or whatever else would work...)I haven't made her ride in it again yet, so I doubt she's changed her mind much. I bet some "de-ghettoification" would be helpful too. It'll look better after I fix the fender and find a new lens for the marker light on the front. Oh, and the blurry tint needs to go too, it's annoying. Quote Selected
Missing and stalling Reply #41 – May 18, 2012, 02:02:05 PM Oh, one more weird driving quirk I noticed today. Whenever I turn hard (or powerslide...) to the right, it will cut out shortly after. I'd bet it's fuel sloshing around in the tank causing it, but I've never experienced that before in any other Fox. Maybe when I get near the bottom of the tank, I'll drop it and make sure the pickup is fully submerged. Quote Selected
Missing and stalling Reply #42 – May 18, 2012, 02:18:03 PM Baffle in the tank may have broke loose. Common issue with the Mustangs and the Birds. If you drop the tank double check the sock on the inlet side of the FP.Darren Quote Selected
Missing and stalling Reply #43 – May 18, 2012, 03:02:31 PM That kinda what I was assuming, though I wasn't sure there was a baffle in there. Easy diagnosis, not so easy to crawl under it and fix it... Quote Selected
