Got some errors on daughter's 1.8 Zafira petrol hope someone can point me in the right direction to solve.

Ran diagnostics about a week ago and got the following errors:

P0100 - (2) Mass or Volume Air Flow circuit low input - Present
P0325 - (8) Knock Sensor 1 Circuit no Signal - Not present
P0170 - (2) Lean exhaust - Not present.

I cleared them off about a week ago and they are back again.

I cleared them today, started the car and P0100 came back straight away.
I am assuming the other two will come back once the can has been for a run.

I have just been informed by daughter that the car needs a full engine service (one of the many jobs on my list). Will that solve the problems or is it worse?

Many thanks,
Malcolm.

being a vauxhall and going by the first code i would say stick an air flow meter on it. vauxhall seem to suffer worse than others for them failing

Heeeelp

Pretty much decided a new MAF was due, but car was running OK so I thought I would do the brakes first. New disks and pads all round, bled the system then came to start the car and ran like a bag of shite. On starting rev'd up near 4k, then settled down to a very erratic tick over around 1K, then up to 2.5 - 3K every now and then. These is the symptoms of a knackered MAF? bought a new one, fitted it, still running exactly the same. Put it back on Op-Com now comes up with different errors

Any suggestion please.

the ticking is probably ya timing chain the tensiors start to fail and thats the result of it. they handy enough done but a kit with the tools to lock the engine up to do it is around 150 i done one there recently on her corsa. theres cheaper kits about but they not gm parts and ya don't get the locking kits with them

Sounds like a Lamda sensor if thats the right spelling

Sorted. When I changed the MAF sensor, vacuum pipe to the throttle body had come loose. Did not notice it until I was getting ready to remove the throttle body to clean it and noticed the unattached pipe.
