Backround.
The car is actually a 1971 Opel GT. I had the engine and 5 speed manual transmission installed on the car replacing the 1.9 that came with the Opel. The engine and tranny are from a 1988 Ford Thuderbird. It is the 2.3 liter model with the turbocharger.
Problem.
When I start the car, and especially so in colder weather, it revs pretty high for a good bit and black smoke comes out the exhaust. Then after a minute or so the car will drop the RPM, but the idle is not anywhere near smooth and even. It is not crazy, but it is up and down.
When I backout of my carport, it does so fairly easily. When I use 1st, 2nd or 3rd, it shifts into the gear easily enough, I apply the gas pedal and it will start to accelerate, but then will be hesitating (a la' a chunka chunka chunka). If I mash the accelerator to the floor, it reacts as if it is not getting any more gas and does not accelerate.
Now, after about 10 minutes or so (of driving around my development, it will hit a certain point and all of a sudden I have full gas pedal and acceleration but there will still be some black smoke coming out of the exhaust as well. Also of note is that even after running at highway speeds, when I come to a stop, down shifting and all that, the cars idle goes down and the car acts like and sometimes does stall. It starts right up again but I have taken to having my foot on the brake and sliding part of my foot over to keep a little pressure on the accelerator so it will not stall.
Of note.I have been paying attention to the oil, and the car does not seem to be burning any oil. The turbocharger seems ok when driving as well. I was thinking that maybe the turbocharger was leaking oil. But again the oil level on the dipstick has stayed constant.
OK, what might me my issue(s)? I am hoping someone will say it is fuel injectors. Is it also possible that the spark plugs are wonky? Air sensor of some kind? HELP PLEASE!
Thanks so much for reading.
