what ways are there to test ur injectors? i think i might either have a bad flowing, or a sticking injetor... and since i am going to have the upper plenum and runners off pretty soon anyways. i was wondering if i could take out the injectors and maybe try to test them somehow. (ie trying to start the car and watching them. or bringing them somehwere to have them tested. or just hot wiring them or something) they are pretty dang noisey. but i heard that was a sign of clean injectors...? but im noticed a pretty bad miss throughout the whole RPM range. especialy when slowly accelerating to about 3400, 4000 rpms.. its like ill accelerate and then the engine will kinda miss or slow or something.. and at certain low rpms. when im starting to take off (just recently installed a t-56) the engine will kinda buck pretty bad, and this is at like 1500 rpms in both 1st and 2nd gear, so i know that its not too much of a load on the engine. also i hooked up a scan tool to my car. and i noticed that around 4500 rpms or so, sometimes the rpms will go from like 4350, 4500 then back to 4300 again.. i don't understand why the engine speed will drop like that at WOT..! any clues? ill try to post a more detailed summary tomorrow, im kinda tired tonight but just frustrated with this car...

 

Look for a semi truck garage in your area. If they don't have a flow tester, then they'll know where you can go.

About 90% of diesel engines have injectors on them. And they cost a lot more than the injectors for our cars. It's much more cost effective to check and possibly repair a diesel injector than it is to buy a new one. At least that's what I've been told by a guy I know that works at a truck garage.

If you're going to have the injectors out anyway, you might as well box them up and send them to Cruzin' Performance for cleaning and flow testing/matching. At $10 per injector, it should almost be an automatic response to removing an injector - like changing the filter when you drain the oil. Rich will email you a report on the condition and flows as soon as he gets the data, and usually sends them back in a few days. If you can spare a few days of cleaning time, it's certainly worth the cost.

 

I used local BOSCH dealer.

CH$ 6.000 per cleaning and testing one injector (= US$ 8 each) without mail costs.

 

Yes, but Rich will also flow match them. Meaning, he will switch out certain injectors of yours with others in his stock until he has the flow amount between all eight injectors within about 2% of each other.
