Lanos 1.5, 1999, E-Tec - Powerloss, vibrating...

[Klincman]

I have Lanos 1.5, 1999, E-Tec...

the first problem was 2 month ago, bicause one morning didn't start (-10°C), next day friend came with his car and pull me... and Lanos started. But day after that and ever since then I have problems... sometimes it works, smooth, starts nicely other days starts in first try but not smooth and it vibrates alot (whole car), and theres huge powerloss it feels like it works only on 3 cylinders.

So what could be the problem? In nice weather let's say 25+ °C USUALLY works fine, but for example today (15°C) it doesn't.

spark cables, plugs are about 1 year old, I already tried remowing air filter, fuel cap... no difference

I'm using 10W40 oil, replaced 1 month ago.

And yeah, sometimes usually when it's nice and warm weather vibrating stops and car gets back power... while I'm driving. Let's say I drive 45km/h in 4 and it's starts going roughly for about 10, 15 seconds then it's fine, no vibrating, no powerloss - until I start it again after some time... hours, days, ... randomly.

Any ideas?

why not check the easy stuff, like the battery and terminals? when it is warmer starting will require less battery. I ahve had my terminals corrode and experience similar issues. Once it is runnint he alternator makes enough power to keep things going, but may run rough for a while. I would remove and clean your battery terminals and check your battery. how old is it?

Battery is 1 month old... and I cleaned battery terminals when I switched the battery.
