OK, if it is P0102, then here are some steps to take:
- check for objects blocking the MAF screen
- check for vacuum leaks around intake manifold, throttle body, and EGR
- check for a malfunctioning PCV
- check for poor electrical connections on the MAF sensor
Also, indicated is a cleaning of the throttle body and IAC and checking to make sure air filter is not clogged. I assume an inspection and a cleaning of the MAF sensor wires would also be a good idea.

Thank you, I wil try to see the connectors.
Air filter is new. PCV valve is just 30k km old.
I am sorry but where is located:
1 the MAF screen
2 throttle body, and EGR
3 electrical connections on the MAF sensor
should I lift that plastic blanket from the engine, or is it all arround the airway?
Appreciate your advises.

MAF screen is located just inside the round opening on the trottle body. You can see it when you take off the black tubing connecting to the throttle body.
MAF sensor is located on top of the throttle body. A black plastic box with three screws that hold it onto the top of throttle body. There is a wire connector plugged into it. The screws require a special "Security Torx" tool to remove them.
EGR is a black cylinder that is mounted on top of the engine, behind the throttle body.
I don't have any detailed pictures to point you to at the moment, so you might want to type these items into the "Search" function (located near the top of the screen, so maybe you can find some pictures and better descriptions or maybe there is a member near you that could help out.

TB is usually used as an abreviation for "Throttle Body"
TP is used for "Throttle Position". Think of it as the position of the gas pedal.
MAF is "Mass Air Flow".
We were all new to this at one point or another, and getting used to the components and names and abbreviations takes awhile.
Read up on as much as you can and if you are going to tackle this stuff, yourself, we will do the best we can to guide you through it. But at times we forget to calll out things by name.
Again, if you tell us were you are located at, maybe someone nearby is willing to assist you.
Also, please trun your "CAPS" lock off on your computer. We know you are just looking for some help here, but typing in all caps is considered yelling on an internet forum, and nobody likes tobe yelled at

Good day,
Sorry for the caps, just I can see it better when I anfully tired fm hectic days...
Thank you for the advise ""Echo SSEI""" and appreciate clearing some acronyms and abbeviations. I kinda before researched ok MAF but TB in internet usually commes out as Tuberculosis, so thanks.
I am located in Montreal. Would be cool to find out of the Bonneville fans here.
Believe TPS is Throttle position sensor?
Will try to tackle, but would be great to know somebody that dealed w that before.
Thank you all

There is a lot to learn but many of the things can be done by most folks here. Again, we are here to help if we can.
We do have some Montreal members. Not sure if any can lend a hand, but if not, we will try to walk you through it.

Maybe my car is CHRISTINE?
Just got the cleaners, set of safety torx'es, other tools...and..suddenly.....the check engine light is gone, engine is smooth, revs nice within 800RPM range when engine idles....hm....
Well lets see how she will turn on tomorrow....as going to get TB mounting gasket (believe this is the one).
How long this project would take in HRS? 5hrs about?
Will let you know how it went. And thank you all for your help and advises.
