Bucking car

I have a 1999 Hyundai Accent manual transmission. It’s been a great car but over the past few months there is a problem that the mechanics can’t figure out. The car is fine driving initially. Once it’s warmed up, parked for about an hour, and started up again, it bucks every time I ease up on the gas. It seems to be worse at slow speeds - 30 or under - but still occurs at higher speeds. Any thoughts?

Sounds like you are developing a “miss” and it is happening after heat soak… Basically what I am saying is that it is taking a good long time for the coil or wires to get hot enough to reveal any cracks that would then leak out voltage and make your engine miss.

Do a tuneup…plugs distrib cap and rotor and see what you get…if fixed then great if not…then replace the wires.

Thanks! I’ll check this out.
