Oppo, I need your advise. My ‘88 205 CTI hesitates quite a lot while accelerating. Especially around the 2700-3300 rpm range. I’ve got another car with an identical drive train (‘88 gti) that accelerates smoothly, so I know how it should behave. What could cause this, and what can I do?

My first thought were the spark plugs. The are only 6k km (but 2 years) old, just like the air and fuel filter. Spark plug cables are 3.5 years/16k km old. This leads me to believe all this stuff is probably too new to cause such problem, but that’s just a guess.

The car drives just fine at a constant speed, even within the 2700-3300 range. Starts and idles fine too.
