You could get your old ones cleaned professionally by a place like CruzinPerformance.<p>Many of us have had great success with them and depending on what you need done, a cleaning and new injector seals is $75-80 or so. That's a whole lot cheaper than buying brand new injectors from Volvo at over $100 per injector.
does the cleaning really work with a car with this many miles it is really down on power but I keep fresh plugs,cap,rotor and filters in car and run injector cleaner in gass every 3 tanks of gas but it just doesn't have much zip anymore I know the cleaning is about 100.00 with shipping but would it be better to just get new one's?
I did cleaning recently (car has 225 kMiles), I think engine works really smooth now, but I did belts/idlers at the same time. They provide me with printed receipt showing that 2 or 3 injectors were in bad condition. I thing looking back I would probably did it again instead buying new set. I paid about 140 shipping included.<br>I don't run injector cleaners, but I always use Sunoco 93 plus and use Mobil 1 with OEM filters, OEM plugs and all other OEM crap. <br> <br>
I had several sets of injectors cleaned by them with great results. The ones from my car had about 145K on them and 2 other sets with high but unknown mileage.<p>It's worth a try at the very least b/c even if on some weird chance that not all of them can be properly brought back to life you won't have to buy 5 new ones.
