Hi to all
last week changed the rad on my 2.5 and then afterwards the EML light came on? did paper clip test an got code 69 an 73
69-Intake air temp low.
73-mass air flow sensor voltage low.
Cleaned intake sensor and MAS sensor.
Now am getting code 73 and 74
74-mass air flow sensor voltage high??
does this mean MAS unit past it or is there something i've missed? Please help! am gettin really confused by all this!
funny thing is the car the car starts and idles fine But stutters when accelerating?

what did you use for cleaning ?

[symes]

electrical contact spray

[cem_devecioglu]

check the spray contents.. air flow meters (MAF) are very sensitive to chemicals.. and also they are really  tiny/fragile materials..

clean the sockets and plug on/off several times..

may be when working on radiator you disturb the cables somewhere else.. :-/


also if you have a multimeter handy you can measure the impedances of sensors and cables ..

The only safe thing to clean the MAF sensor with that is readily available to the General Public is Isopropyl Alcohol which is 98.9% pure Alcohol. Some have the opinion that cleaning the Maf doesn't work, and I can only speak for my own experiences of cleaning mine which have been successful.

found problem-NUMPTY(me) put plugs to air cut off valve and intake air temp sensors around the wrong way .
If an award for being daft I'll accept it !!!!!
Many thanks for your advice I noticed problem when checking wiring..
