    As a CFI owner this is the truth. There were a couple times sitting at a light I thought the engine had stalled it was running so smooth. Getting it to that point however was definitely some work. Biggest thing is good vacuum lines and a quality timing chain. When the timing chain stretches funky things happen.

    It was all cleaned up when I bought it. These rust free cars always look so good under the hood. All I did was remove all the smog pump BS off the pass side inner fender, and clean up the wiring a bit.

    Good luck with that MSD coil, I've had nothing but trouble with them. In case they're still garbage, you might want to keep the factree one in the trunk.
    The CFI does look good, that's the only compliment I'll give it. The wheels and a quick buff did wonders though!
    As for the coil, that one has at least 50k miles on it. It lived on the old battle wagon most of it's life, and floated around vehicles ever since. It's at least a decade old now. My buddy bought one for his Bronco many years ago, and it didn't even last a month.

    That is true for sure. My old 85 LTD ran super smooth, and got decent mpg on flat land. Once you got into the hills, or made the CFI do any sort of work, it plummeted though. The SEFI HO conversion I did on it make it 100x better.

    Thanks Dave! It's a simple build so far, but it's coming along I think!

    I just can't do CFI. Exhaust flappers, heat risers, high idle solenoids, I just can't do it.


    If this car didn't leak a drop, I'd maybe leave it alone, but like all low mileage 36 year old cars, all it needs is everything. The engine needs a full regasketing, and there's no reason to regasket a boat anchor.

    I'm kinda in the same boat on the CFI. I've gotten mine to first run like garbage, then to like crap, to okay and now it runs about tolerably. It needs every damn vacuum hose replaced, EGR control gets brain farts constantly and makes it undriveable unless unhooked. High idle mechanism is broken and probably 5 other things arent quite how they should.
    I would've probably done SEFI already if the parts were available here.

    But hey my CFI boat anchor has run smooth as butter atleast, like 7 times. That was cool.

    Glad you got a good coil. I went through two on my Fireturd. When the second one almost got me killed, I was done. So it's got an MSD ignition box, billet dizzy and matching MSD wires yet factory coil..

    I had an MSD coil on my ‘95 Cobra that died a very slow death over the course of about five years. It started around 2012 as a momentary throttle blip that would occur randomly. It progressed to a blip that occurred a few times every time I drove it. It finally got to the point where the car would sputter and had no acceleration. Put a new Motorcraft coil in it around 2017 and it’s been fine ever since.

    PI front sway bar is on. Had new poly end links laying around, just had to buy new bushings. Also grabbed the wagon/90+ "frame braces" off the old 87 wagon frame. Both got a quick scuff and shoot before going on the car.

    Replaced the dirty A/F with a fram RA $2 closeout.
    Replaced the original belts (factory motorcraft's) that were really rough with some really cheap $5 closeout Prestone belts from RA. (never even knew they made belts) The typical 560k6 smog pump delete belt was extremely tight to get on, had to cheat it quite a bit.

    Forgot how insanely gutless CFI cars were. It runs decent but can't get out of it's own way. My Super Duty with this car on a trailer behind it would run circles around it. It cruises nice though and gets a lot of looks + thumbs up's at least.

    Thanks! The car certainly falls under the "far from perfect, but perfect from afar" rule.
    Trying to not make a project out of it, but I have a really hard time not modifying things. The fact that my boat anchor is leaking various fluids makes it even harder to not just rip the entire drivetrain out right now.

    After driving this to work a few times, I knew something wasn't right power wise. I remember my old 85 CFI vic being slow, but not "scary to merge on to the thruway" slow. Soon as this car hit 3rd, it was like an anchor was thrown out the window. It otherwise ran great, a little surging/hesitation from time to time, but nothing unexpected, ran smooth for the most part.

    I figured the timing had to be off, a quick look at the distributor showed a new aftermarket TFI module, other wise looked factory. Cleaned up the balancer, drew some fresh lines (no one had ever marked it before that I could tell) and busted out the timing light. Sure as shit, with the SPOUT unplugged (is it still called the spout on CFI cars? I forget) timing wasn't at the usual 10* BTDC, but at 10* ATDC! No wonders it was so damn slow. Adjusted it to 14* BTDC and holy shit, I think I doubled the horsepower of this thing. Drives just as good as any SEFI lopo I've ever owned. Had to turn the curb idle back down since it was way to high after, but man does this car run good now!

    Can vouch for mistimed lopo falling to the nopo level. Glad you got this one moved up!

    heh... yeah... noting which 10º mark to use is sometimes overlooked when in a hurry to get it working to sell. Looks like you got one of those.

    I'm surprised to hear it fired up and went on 10* ADTC. All the SEFI cars I've futzed with definitely did not like trying to start easily with the timing near or past 0*. Guess CFI finds a way.

    Engine bay looks really nice after your smog de-cluttering.

    wow that might be the cleanest CFI engine bay I remember seeing. Good to hear it got some power back! Now it's safe from an engine swap for another month

    I drove all the way to Virginia once before realizing mine was at 10 ATDC. Ran like ass and ate fuel like mad, realized I was an idiot, fixed the timing, all was well.
