How to - Update?

Normally cloudy = water. Since you have been driving the car that's unlikely. If it is water it will settle into two distinct layers in a few minutes.

There is not normally a lot of fuel flow through the CPR. It just bleeds off tiny amounts of fuel to adjust pressures within the fuel distributor. I don't think that's conclusive.

If you do the flow test at very low flow, long enough to fill the bottles, are they even?

It can be hard to see but you want the fuel to come out in a mist, no jets or streams. Doing this you can only check pattern and amount, not opening and closing pressures which is also important. This is a very rough kind of test, injectors are best tested in an injector cleaner/tester. Be careful to not bend the fuel lines too tightly, you can damage them.Testing them this way (on the motor) also presumes ALL of the other parts in the fuel system are working correctly. If the injectors are only a little dirty you can clean them up by using Techron with a full tank of gas. One of the best ways to check if everything is working well is to keep track of your gas mileage. You should be in the low to mid 20's.

Although the amount was "fairly even", you should do the timed test....the injectors may be fairly equally clogged (where streams and/or erratic flow would be expected)...
Sounds like professional cleaning/replacement time so far.

Anyone know the Bosch part# for the injectors I think they are 0 437 502 013 but not totally sure. Agree??

Before you start thinking injectors are the problem, make sure you've first eliminated the fuel distributor / fuel lines from the FD to the injectors. You can do this by following the additional instruction that I posted in the 'how to.' At first, I thought that I had two dirty/faulty injectors, however, it was really the fuel distributor (most likely a bad center plate/diaphragm).

So Im toying with the idea of replacing my injectors but not sure what to look out for according to the part numbers. I have been flipping through the Volvo CIS manual I found somewhere on this site (great book btw). In the book it shows the injector number is a Bosch: 0 437 502 005 replaced by 0 437 502 013. I would think these injectors would work because the engine looks exactly the same. When I popped by the car to investigate I find my injectors are - 0 437 502 022 . All of these look the same other than one looks a little longer but, being able to move it up a little higher on the boot may be fine (I guess). I'm just not sure of the differences? Can it be pressure related? Is there a list of compatible injectors with PRV engines? I think we should take a pole to see how many different part numbers we can get together. Thoughts??

Thanks Ron, just to be clear. The injectors I have in the car (0437-502-022) do fit and are not another PO F up. And can be replaced with 0437-502-013. I think thats exactly what you wrote but just to be "clear"

Yep.

Check this out!
If you go to RockAuto and poke in 0437502013 or 0437502022 instead selecting Delorean in the catalog, the price is $42.79 instead of $63.79/$67.79! And they are Bosch!

I don't know what's up with the -751-014 suffix missing, but the 0437-502-013 looks like a good deal for us.

God thats great news! I just purchased 7 of them on ebay. They are new in box and got a great price so I couldnt turn it down. Now Im really glad I can use them .. It seems you always have the answers I want to hear! Thanks again Ron - you da man.
