Hello people!
Looked through the posts and didn't see any that would clear my problem.
So the problem is that before putting my car to winter sleep, made a little fast driving, to make last fun, but when I made full throttle the car started to spit and stuggle when I reached 130 kmph. Spark plugs are new, spark wires are good. What could be the problem? Some say it's ignition?!
Thanks in advance.
