Thought I'd post this up since I was a bit surprised to hear it myself. My setup had been running *lean* (edit) since I put it together. Figured that was due to all the changes I had made to the motor. Since I had the odd no-start problem (solved with a new ECM, not a battery as a "professional" had emphasized it was, because as a "layperson", I couldn't possibly know better than him lol) figured it would be a good idea to swap injectors now that issue was gone. All the injectors were "good" according to the meter, 13-16 ohms each. I had no qualms selling them, since I knew the engine ran with them, they tested good the only way I could check, and I wasn't selling them for much. Sure glad I didn't waste my money having them professionally tested, that would have cost me more than $100, then still had to spring for the replacement cost of the injectors as well! Also not even close to worth it to buy equipment that could test them differently than you can with a meter. Here's a quote from the email I got from the guy I sold them to: "Well I got $27 (my note: $20+shipping) worth out of them. I flow checked them today and two of them could barely open. I sonic cleaned them and nothing changed. The coils in them are just weak. The other 6 spray excellent though. LOL. I work for Accel so we have an injector machine." So I guess it goes to show that you shouldn't chase your tail if you don't know the injectors are good, for sure. I didn't waste time or money trying to fix that problem with tuning (thankfully) but I could certainly see how you could. If you can't afford new injectors, it probably isn't a bad idea to send the old ones in to make sure they work correctly before throwing your setup together. My 24# Ford injectors are all in and ready to fire up, as soon as I get my tuning/chip burning software installed again, since I lost my hard drives.
