Hello dear forum, since I am a newcomer, first of all many thanks for the many good information that I have already read with you and which have helped me more often:-) Unfortunately, this time the search did not help me, therefore here the topic: My ’96 S40 1,8 257tkm annoyed me recently with the following behavior: At low speed (1100 – 1700 rpm) a stutter occurs during acceleration. Last year a ignition coil passed over Jordan, the 2nd I (since then a similar behavior was) now also replaced. Unfortunately without success. Unfortunately, also the ignition plugs, the air filter and an oil change are new. Unfortunately, the friendly one (so this means here, or?) on site meant that it could be a cooked thrush flap, I let it clean (One hour work – 95 €!!! is normal) again without speed … Unfortunately again without success (the whole response behavior of the engine has become noticeably better by the various measures) STOTTER?
