I have an Impreza, MY95, with 1.8l engine (around 120K km/74K miles)... The car seems to loose power when driving/accelerating in low rpm range. For example - it's tricky to start moving in 2nd gear, because the engine won't react promptly, chocking itself a bit. When driving in 3-3500+ rpm range, everything seems to be normal. Does anyone have some idea what could be wrong (have new sparks, cables, no detected errors when testing ecu) or have any experience with the same problem?

And please, don't recommend some of your service wizards, 'cause I can't reach them. :-) Thanx in advance.

Greetings from Croatia, K.
