Hi all,

My 156 ts1.8 drives well (i believe) although when idling it isn't smooth. The rev counter doesn't bounce or anything, like some threads read. but the actual car seem to vibrate and shudder.. the sound of the engine also when idling tends to be 'pulse' like. as soon as i press the throttle and allow some revs this all then smooths out and sound normal etc.
It never has but sort of feels like it might stall...??

ANyone now why ? would it help to clean the MAF sensor? or do an ECU reset?

Thanks

Try see some of my threads ... have the same problem :) ... found a leak in the exhaust flexpipe that I will try next ... my guess is that the lambda gets daft readings due to airleaks ... But I have allready replaced: Airfilter, MAF, Inlet hose, Inlet Valve, Spark Plugs, Ign. Coils ... result = small improvement ;-)
