Thanks for all the injector advice. I decided to call Motor Man and got in touch with the owner named Howard. Super nice guy and very knowledgeable. He has $25,000 worth of equipment dedicated to injector cleaning and refurbishment. He spend almost 15 mins on the phone with me talking about what they do the process and general injector information. He does a series of tests on the injectors that include, leak checks, resistance, coil check, and flow rates. He tests individual flow rate and compares to the entire lot to see if there is one over or under performing. He replaces the small filter in each injector, new o-rings and also sand blast to remover corrosion and puta them in a ultra Sonics bath for about an hour and then puts a clear protective coating on them. He said the parts for top feed injectors alone are $5 each and will be as such will be raising prices soon as $14.99 each is not economically viable anymore. Probably increasing to $20 soon. He also lubricates the internals before shipping for people who may store them for months prior to install. I’m going to give this guy a chance and report back to you all what they look like coming back. He has a 100% satisfaction guarantee and provides an individual report of each injectors performance.
