Good afternoon all!
Got the following errorcodes on my 2.2i/Z22XE ; P1555 , P0100 , P0110.
Cleaned the throtlebody more then once yet , getting poor on gaskets 
Has anyone got some good advice what to check or replace before i spend
lots of euros on parts that aren't faulty afterwards...I suspect the air mass meter,
but not sure. Some say it could be the cam sensor..?!
Thanks in advance!

Thanks for the link , but was allready aware of the codes 
It's either the throttlebody or the air mass meter , but not sure..
Nobody ever had those three codes together?

[grain.ben]

If it was me, i would make sure the throttle body is clean and the butterflys open and close freely, change the tb gasket, check the breathers are nice and clean, but it does sound like a faulty MAF.

Im sure some of the other guys might have a different opinion

faulty MAF can cause all sorts of problems-would bet its that

Take off the MAF, remove the plastic grill from one end and either spray or GENTLY brush the sensor wire with Isopropylene Alcohol with a soft haired small paintbrush. Replace the grill, refit the MAF. Despite what some may say, this has worked for me twice in the past 3 years. It may NOT work in your case, but worth trying before forking out for a new MAF imho 
Also, whilst the MAF multiplug is removed, make sure the connector pins are clean and free from greasy deposits.

Sorry for the very late reply , but all thanks for your advice 
I'll check the MAF later today for "dirt" and will try to clean with alcohol (got that at work)
Better worth trying before spending lots of money..
This morning however it started fast (normally not) but it ran really bad..
Got the codes P0170 and P0302 now... The MAF codes are gone. I'll see what happens
later today on the way home...Wish me luck 

Thanks Maurice

Well , cleaned out the trottlebody today , replaced all lines/tubes connected.
Measured the MAF and foud something strange...maybe you could help me out here..
Got a MAF with 4 connectors , 1 till 3 have "X" kOhms and 4 has none/unlimited..tells me there is a
connection lost/broken. Don't know how they pair inside the MAF , tried all possible but connector 4 gives
no ohm's back.. Connector on the car says (with contact on/car not running) 1- 4.96V / 2- 0V / 3- 0V / 4- 12.09V
