94 ST 7A-FE, 3 quarts of oil and misfiring. Options

[Steevo]

Hi!


Let me just start out by kissing everbodys feet.



I have come into possesion through marriage (told her I would get it) of one of these nice cars.


But there are a few problems that I am having, other then her brother warping my new pressure plate and burning the clutch and taking out second syncro. Me and him and a piece of heater hose have a date in a dark alley.......


First off I have a mis-fire that is recurring but only between 2K and 4K RPM. It sounds just like the fuel gets shut off for a couple miliseconds, about every 10 seconds. I can also hold it at 5K or so and it will slowly increase RPM as it adjusts fuel mixture, that is normal. But when dropped back to 3K it starts dropping RPM untill the mis-fire is back.

I believe it is running too rich as I can wipe the end of the exhaust tip and go for a short drive and the light black film is back.

So far I have been advised by the "local" (50 miles away) to change the front O2 sensor, plugs, rotor, cap, wires, check timing, check fuel pressure, change fuel filter, etc.....

No dice.

Next problem is the missing three quarts of oil. Has anyone seen them? From every indication they haven't been burnt, but the belts have gotten wet from oil when I ran synthetic Mobil One through it, I changed to 10W30 oil. But it doesn't leave oil drips from what i have seen. It doesn't smoke. And it has only been 2,000 miles or so between changes.

I don't know if it is pushing oil out during driving or while the engine is running, and I honestly haven't had the time to check. I'm just looking for some insight here.


I used to turn wrenches on domestic stuff for fun and a bit of money, so that part isn't new to me. But these two problems have me perplexed.



Now for the good stuff.

1994 Toyota Celica ST Hatchback Rennisance Red
1.8Liter DOHC
K&N filter, larger PVC intake tube. (no laughing)
Corbeau Seats
Pioneer Premier System
Basic 200W AMP with a BOSE Acoustamass module
Napa clutch kit (she didn't want to spend the money for stage one puck clutch)
Custom dark black tinting.
Did have a short throw shift kit, but the bushings kept cracking, and the knob would come loose.
Changed tranny fluid from 75W90 to ATF for better shifting.
And I have a set of Pirelli P6000 on the way. Looking forward to burning up the no-names on it.

Just checked it over again before lunch and took it on a few runs.


0-60 12seconds on video, I don't know how this rates.
And some video, of 100MPH on a short run. Up and down a off and on ramp.


The sound on the video is crappy, but that is on a PC here at work. So I will check it later, plus me grinding some gears trying to shift, steer, and hold the camera. But I did get the misfire, if you can hear it. I ran it clean at 5800RPM then dropped to 3200RPM and it did it a few times.
