Car keeps losing power!
Discussion
afternoon,
I'm having a bit of a problem with my car. it's a 2008 Chevrolet Lacetti SE 1.4, and it frequently loses pretty much all power after its warmed up. If I'm stopped it only just has enough power to keep the engine turning over, and if I'm driving I just start to slow down, until the engine regains power and continues on, until it happens again. generally speaking it happens at between 2500-3500 revs, if I'm going over that the issue isn't as prevalent, however less than that, like it traffic, its a real problem. If I turn the car off and on again it'll get rid of the problem for about 30 seconds - which is usually enough time to get away from traffic lights and areas that'll cause a hold up.
It used to bring up the error code P0132 High voltage on O2 sensor, so i had the o2 sensor replaced, but the problem persisted without that code (occasionally now bringing up the code low voltage on o2 sensor - cant find the code atm).
also during this time, I've noticed the fuel economy has also gone down the pan closer to 20mpg rather than the previous 30mpg.
Whilst this problem has been happening, i feel like I've replaced most things that could have caused it (and some that probably wouldnt have, but got replaced anyway). These are: both O2 sensors, the air filter, all spark plugs, fuel filter, and the map sensor. I've also run a bottle of Redex through to clean the injectors.
Is there anything else that i should look into before i throw in the towel and get a 'new' (probably another crap) car?
TIA
Ben

Loses power. Does it feel rough? Like maybe one cylinder not firing? What kind of ignition? Is it a single coil pack with leads to the spark plugs or coil on plug.
I'd suggest it's losing spark when it gets hot. Could be dodgy coil or coil pack. Check spark plugs for one that seems wet, smells of petrol. Could be leads from coil pack to spark plugs. Most often these days it's coil on plug and the coil or head top coil pack(GM) needs replaced.
