low rpm problem corsa b 1.0

[fielpo]

hi all, i'm here again with another problem on my corsa b 1.0
the car start the engine fine, and it keeps the rpm around 1k but after i start moving theres the problems
so the problems are 2:

1. when i accelerates and then leave the accelerator somethimes it come back at 1k rpm with no problems, but mostly of the time it stuck at around 1500rpm and start to go up and down fast like from 1500rpm to 1600rpm. i must press the accellerator once or twice and then it will go down to the right minimum rpm 1k.

2. at low rpm, when accelerate the car doesen't have "power", it's like soffocated, i must rise up the rpm and then start have some power. i even had some diffiult in some small climbs

i changed the maff with a cheap ebay one, and have the egr blanked...so i thought it could be the icv?

I also think icv, the cheap maf tend not to last very long

Does it seem to splutter and almost misfire when the second problem happens then be alright at higher revs?

if i understand what you mean (english it's not my first language), the sound it's regular, no splutter or else, it's just doesen't have power, i need to raise up rpm and then at high rpm go fine
