I have an n/a '89 supra. This problem just started about a week ago. I've pulled my 300zx out since then since I can't keep the Supra running when it's cold
A few months ago I noticed that if the engine was very cold, it would kind of stutter and hesitate when you tried to get on it a little too much (just going up a hill or accelerating quickly into traffic). It was mostly just a little choke, like an iced over carb or something.
A week ago, I started the car up and it felt like it had no power. I could barely get the car over 25 mph. I got it to the top of the hill and then it stumbled and quit. I backed it down the hill when it wouldn't start back up. I tried and tried, but it wouldn't fire up. I left it sit for awhile, came back, and it fired, leading to me to believe that it may have flooded. The engine still ran like crap and stalled again, but it fired up and was ok after that. When warm, it's fine. When fired up after 4 hours or so, it was fine. It stalled out and won't start again 3 or 4 times since then. It will crank and crank, but no go.
Any ideas? I pulled a couple plugs and they looked fine. I'm guessing it's one of the 1,000 stupid ECU/EFI sensors. The car was also fairly low on antifreeze due to a tiny hole in a coolant hose I haven't gotten around to fixing.
