I want to get my injectors flushed on my quest for LH perfection. Already have replaced FPR, O2, KS, TempSensor, TB clean, Calibrated AMM, Air leak test etc.
I stopped in to my local Euro-shop and they want $45 per injector!!!!!!!!!!
I almost burst out laughing as he explained how they would totally rebuild my injectors from scratch to better than new condition. They don't even do it themselves. There was an injector service van parked out front and he had to run out and ask them if they did Volvo injectors. What???????? What is a reasonable price for a flush job? And where to get it done? I am willing to buy four junkyard injectors and send them out and rotate them with the ones I hav installed now. That way I would have a fresh pair on hand always. Any recommendations? I have no injector experience as of yet.

I can recommend Marren Fuel Injection,

They did mine, coast to coast, in less than a week; the engine is noticeably smoother.

Check the FAQ for detailed info on doing it yourself. Also recommendations for places to send them out.

When I do mine (planning on this summer -- which, here in Maine is a 48 hour period some time in mid-July) I'll use a compressor air-drier and straight Techron to flush them myself. But I own a compressor.

I have seen this outfit recommended here & elsewhere:

I think clean/balance/new seals = $11/per injector + shipping.

Haven't used them myself... I'm also thinking about getting a second set of injectors & sending em out... so I don't have to keep my car off the road.

I would buy the repair kit 4.50 per (Python injector seals includes inlet screen as well as seals and injector cap.) and clean and replace.

Don't have the answer for you but I'll do a web search as I'm interested also. BTW, what are you trying to fix? What kind of symptoms or problems are you having? I'm experiencing hesitation and have replaced the FPR and have a salvage yard knock sensor to try. A TB cleaning was my next project.

Thanks,

For a few bucks, you can try a bottle of AMSOIL PI and see if it doesn't help.
Aternatives: Redline SL-1, BG-44K, Techron.

Snakeoils will not FIX anything. Solve the problem or put the snakeoil in it and sell it. MTCW

I want to try to smooth out the idle a little. According to the FAQ, Dirty injectors can be the culprit in a rough idle and poor accel and decel. Once the injectors are in good shape, I can rule them out as a source of idle problems
and it will help me pinpoint where the trouble is. The only thing I haven't replaced it the IAC and the AMM. If you are having hesitation or stalling problems I would definately start with removal and cleaning of the Throttle Body and a thorough check for air leaks. It will only cost you a few bucks, and these two things account for alot of drivability problems. They say not to use Carb cleaner because it eats seals, so I would get some TB cleaner and take a toothbrush to the thing. Mine was really dirty. Replace the gasket and Thumb screw O-ring. Get some fresh Vac hose and replace all your old vac hose. replace your flame trap with a new one at the same time and replace the small hose and inspect the large one to see that it is not clogged or cracked. The vac nipple for the small hose on the flame trap likes to clog up so check that too. Make sure your heater control vac hose has no leaks. Check your air inlet hose between the AMM and the TB for leaks. Once you've cleaned up the TB, replaced all you rubber, and made sure you are air tight once you get past the AMM, and the problem persists I would start to consider other things.
