vr v6 1994 automatic: sensor problems???

[pete30nz]

Hey i have replaced the throttle position sensor. Do you have to set it up some how?

I also got some error codes through self diagnosis after cleaning the oxy sensor and map sensor with brake cleaner :

: 13 oxy sensor - no signal
: 33 manifold absolute pressure sensor - high voltage
: 44 oxy sensor - lean (02) v6
: 45 oxy sensor - rich (02)

Any ideas why these showed up are appreciated

Cheers Pete

I take it you have reset the ECU before doing the diagnosis? Sounds like you have to replace the oxy sensor and MAP... I am sure brake cleaner is a big no no for cleaning the MAP...

yea you should have used an electrical cleaner or even carby cleaner on the MAP sensor

G sorry guys, think i let my self down using brake cleaner.. damn. Im also wondering if the i.a.t sensor: inlet air temp sensor could be ####ed? I know my car has done 285,000 plus a few, but it gives me good power now and then, and other times it sucks. Also getting noise from the lifters i think..
Could the crank angle sensor need a clean? And is there a way to clean it with out taking the pully off?

I have an after market fuel regulator now as well.

Any ideas why, when i foot flat the holden twice in 800 meters it will give me full power the first time, but the second time it kind of surgers / doesn;t give that full power the second time.

Cheers
