Well that data shows essentially the same as post #30 above. Both O2 sensors are switching, although Bank-B voltage range is lower than Bank-A. My understanding is this shows the air-fuel ratios are adjusting more on Bank-A, but not sure which side is better ! Did you try swapping them...

Rather than uploading lots of duplicate pictures that don't show dynamic values, just upload the recording file from Nanocom. Make sure you do the recording at Idle & 2500rpm. Before you upload, change the filename from "xxxxx.csv" to xxxxx.txt or the forum will reject it. Process is the...

BTW, re the thread title, what is "faked" ? or did you mean "failed"

Unless you have O2 sensors after the CAT's (i.e. 2 pre & 2 post), don't bother with the Downstream values. Main focus should be these values: Upstream Bank-A & Bank-B Short term trims Long term trims MAF Throttle & RPM Is the ECU in Closed-Loop or not ? The O2 sensors are switching, so they...

ok. Ignoring . . . .

Pressure test with engine hot & not running ?

Fixed it . . . .but your reply doesn't update

Yes after you guys pointed it out, I checked RAVE & it does vaguely show the correct orientation. Can I be bothered to remove & refit ?? Hmmm.

Look for “RAVE All Models” version. It’s got lots of Classic RR stuff

Definitely needs more investigation. You must be the only one with a P38 EAS pump that can produce that much pressure.

Still got same job on wife's FL1, so will probably get polys for that !!

+1 on the compressor limit. Even with a gauge directly on the pump outlet, I've never seen more than 190psi. Hence why I asked if it was definitely a P38.

Yes they look reasonable to me. Voltage difference could either be differences in the sensor tolerances, or maybe slightly different supply voltage due to contact resistance in the connectors. You could try swapping the snsors over to see if the lower output moves to bank-A. Also give...

Yes they are tight. Old bushes are about 49.85mm dia. The arms are about 49.7mm internal, but are about 0.25,, bigger on one side measured with my vernier. New bushes are 50.2mm even after freezing overnight. So heated the arm ends a bit & got the bushes started in the vice. Then pushed...

Not sure how 1992 differs from 1995, but here's the later diagram with pin & colour info:

Not sure what the valve block seals will handle, but if it really if getting that high, check the pressure relief valve. It should blow off above 180psi.

Absolutely correct. There are loads of electrical noise sources in cars, hence why the HK Audio uses balanced audio connections & have each amplifier grounded. Most likely that car has corroded connectors in the footwells . . . where the balanced audio flows & it's randomly unbalanced ...

Yes. Test it first if you can. They are available, but make sure it's the closed above 140psi type. Many are the other way round. I'm guessing you're Estonian ? Put your town name or local region in your profile !!

+1 on that Keith. . . . it will be HEVAC motors, compressor clutch, condensor failure, SRS connector problems, heated seat failure, tired water pump, rusting steel brake lines, overheating fusebox, leaking rear-view mirror, etc, etc. ;)

Having got the arms & new bushes on the bench I tend to agree, but as I already have the new bushes will try them frozen first !!
