Stephers,
Yup, checked the engine for any air leaks, literally hosed it down with starting fluid at all locations that there might be/could be an air leak. Did the old "Think with your dipstick Jimmy" pull trick and she really started running erratic, took of the oil filler cap on the valve cover and she almost died. I believe a vacuum leak would result in a overly lean running condition, O2 sensor is showing her to be rich.
I appreciate the input though, I'm willing to try just about anything at this point, I've even retested a number of possibles multiple times, second guessing myself, ect...
Wapiennik,
Can't claim this as my original idea, I saw it on another site, where the guy had a very elaborate setup with six 2-liter bottles and was able to run a semi-precise flow test.
My setup is just for functionality, and spray pattern. Air pressure reg. low on compressor outlet, gas in the tubing, wires hooked to battery with in-line bump switch (simulates short electrical pulse to injector). Bottle catches fuel and allows to observe spray pattern. Very simplistic setup, functioned surprisingly well and easy to operate. Tested 12 injectors in about 15min. Wasn't really going for time.
This evening, I'm going to test the cold start valve, and try to test the thermo timer. Those things cost over $100, crikey
I'm going to try to rule it out or something before spending that kind of money.
I have a
