Gs430, Oxygen Sensors And Air Mass Meter

[crow]

hi all

I have a GS430 x reg 2001, with 100K miles, the engine warning light came on and it indicated 1 pre cat oxygen sensor had gone, then the problem came back and now I am being told that I need 2 pre and 2 post cat sensors - a garage i use and trust have said that it may be the air mass meter -

is this a common problem / scenairio ?

any known remedies?

any thoughts ?

and where is best place to buy such parts

thanks in anticipation

thanks for the advice, sorry i dont know the error codes, just that they relate to 2 pre cat and 2 post cat lambdha sensors being faulty

thanks for the tip re cleaning the MAF - will get garage to do it !

Get on to Rock auto Parts in the US! They sold me the two O2 sensors for £98! I ordered

them online on Monday morning... they were at my door wednesday afternoon.. The stealership quoted me £108 each plus vat and told me it would be at least ten days!

Go figure!
