For a while I've notice like misfire between 1200 and 2000 revs
I think it happens after I changed air filter. Maybe coincidence.
I blanked the swirl flaps. I've changed the gaskets on manifold.
It is low on boost according the INPA desired and current values.
No errors on INPA.
Not sure where to look now.
I've ordered vacuum pipes to change all of them but not sure if this will help- hopefully will.
It's 2004 car eu4
Is the MAF will give this ?
I read this will affect the performance under 2k. This happened after I change air filter
Air filter sitting in correct against the maf?
Even if it isn't, shouldn't really give a misfire

It does. I've checked today.
I'm reading now that the faulty MAF will gives hesitation and low power under 2k.
As this happened just next day I changed the airfilter and the old one was black.
Quick update.
I've unplugged the MAF (which brought the engine light) and car drives better.
Better acceleration until 2k and no misfire feeling. Idle revs steady no up or down.
I think this is the problem. I'll try cold engine later on.
When I started car this morning the revs were going up and down slight when cold.
So. Update.
I put new MAF and actually don't think made any changes.
I cleaned MAP and I think this made the difference. Less hesitation that's for sure.
Maybe is on the way out I'll check with INPA the values if bad I'll replace this as well.
Not sure if anyone is reading this, hopefully someone can help me at some stage.
So today I unplugged the vacuum pipe from EGR and blanked it.
Car definitely drives better until 2-3k with good pull and without hesitation.
I tried to push on 3rd gear above 3k and looks like lack of boost. Maybe there is a leak somewhere or egr is always open.
Not sure where to look. My MPG dropped a lot
If someone has an idea feel free to comment.
So far I've changed MAF for Bosh one and cleaned MAP ( which made slightly better - maybe is broken?) how to check in INPA ?
Anything else I need to check?
Unplugging EGR made big difference below 3k.
I've ordered new MAP - Meyle.
I hope this will help
So. After unplugging the EGR car become worst. Lack of power. Also I've got those errors
Anyone could point me out what they mean ? Is those errors are related to MAP ?
136 or 150 bhp?
