Hey,
here's the reason i cant really go through all the testing...first and foremost i live in a small apt with my mom who can not stand to see anything car related in the house so therefore my entire tool box consists of the most limited/basic tools that can fit into my trunk since i need to haul them around.
Secondly, all the shops around are absolutely terrible. They will NOT nor do they know how to test just about anything. They eyeball the issue and replace the part. To run any sort of test or diagnose a car, they charge $75 and up depending. There are also a few knowledgable race shops that would do all work and stuff but they charge the same 75-100 for just the diagnostic, NOTHING ELSE!
So you can imagine how much it will cost to replace something with parts labor and diagnostics...
This is why I have to rely on the internet and repalcing what i can until the problem is solved. I got quoted $300 to install 4 new injectors with their parts just to give you an idea. This is why I spend $30-40 on injectors, replace them and see if they solve the issue. Still cheaper than spending $75 for some careless idiot to tell me that i need to replace them.
Back to the injectors, i just purchased a brand new set from precisionfuelinjectors on ebay. Check out their link and claims. Seems pretty inpressive and i havent seen a single negative review about them.
