I have been recently experiencing this weird buck/dead spot whenever pulling away from a stop or when I am moving slowly and heading uphill and give it more throttle to get up to speed. The first time it did this today was when I just started the car and was pulling out of the work parking lot. It stalled completely and when I went to try and start it, it was cranking really slow like it had a dead battery. I took the key out completely, put it back in, and it started like nothing had happened. It had this weird buck/dead spot issue happen 3 more times on my drive home. And it only bucks once when it does it. My car is a 90 SC with 54k original miles and to my knowledge all of the sensors under the hood are still the original as well as the plugs and wires. Does anyone know where I can start to look for an issue seeing I don't have a check engine light on?
