Lambda sensors - Where, Why and how Much ?
Hi all,
I think my car may need new Lambda sensors. The ECU is a GMP4 1228331, -
same as in the ZR1 - and the car is fitted two, four wire jobbies. Just
been done the local GM dealer, and they want about 100 quid - ($160) EACH
!!!!! Of course, all I can get from the dealer is the Vauxhall/Opel part
number, so I have no way of crossreferencing with Delphi/Bosch/Lucas etc to
get a better deal. So
Question 1. Are all 4 wire Lambda sensors basically the same, so it doesn't
matter which manufacturer I choose ? Even after market ones cost 50 quid
($80) each, so its an expensive mistake if I get it wrong.
Question 2. Anybody got any Bosch or Lucas part numbers that are known to
work with the GMP4. Delphi part numbers also welcome, but it is usually a
problem to order direct from Delphi here in the UK - they often make you go
to Vauxhall.
TIA
