I must be really unlucky with Bosch injectors especially the new ones. Is there something I need to do before I install a brand new injector? Soak it in gas?
A few months ago, DMC did a valve adjustment on my car. When I got my car back, car was shaking at idle. Upon inspection, one of my injectors failed so I got a new one from Amazon. I didn't do the spray test when I installed the new injector. Car was still shaking at idle and never got any better. So I ordered another one from a DMC vendor. This time, I spray tested it but it didn't spray well. It sprayed intermittently. I am thinking that it will eventually spray like the others after several miles. Unfortunately, performance never got better. So I went ahead and ordered another new one from eBay. Today, I spray tested the injector from a DMC vendor and it was barely spraying. So I installed eBay one and it wasn't doing any better. Spraying sporadically.
It is not the distributor because I tested with different lines and different bolts and etc... and still the same. Old ones were working fine at any lines and new one failed at every line. I just cannot believe all three brand new injectors failed????
And how do you store spare injectors? All my working spare injectors didn't work at all. Nothing came out. Totally clogged.
