Question White Tip Spark Plugs?????????

Ok this may sound like a dumb question here, but this is what my problem is, I fixed my PATS security problem, but now I have a new problem *sigh* no breaks for me. Ok here is whats happening, my Saleen is running the following codes, Fuel/ Air Metering, Cylinder #6 and #5 Misfire Detected, and #1 Misfire Detected 1000 revs. I pulled my plugs and they are white tipped at the end / metel coloring. Obviously it is running really lean. Ok one more thing too, the gas that is in my tank has not been used in like 4 months as well ( yeah I know dumb mistake). I added a couple of dry fuel and fuel stabalizers, too see if it would clear it up. No it did not!!!!! Does anyone know how to fix this or what the problem may be. I did notice that while I was driving it, it would like speed up and act somewhat normal like it was pickin up fuel and the piston was firing normaly, but then it would just bog down again. Again any help would be greatly appreciated, and I feel stupid putting this up here, but at this point all I want is for her to run normaly!!!!! I am also running N/A on 80 MM MAF and 19 lb Injectors!!!!!! Please help!!!!!!!! Thanks Jake :larry03gt

Well let me ask this then, are the pink injectors 19 or 21 lbs??? I ve heard that the pink ones are 21 lbs, not sure what my MAF is calibrated for though. Im running like a stock tune on a SCT chip from CCS Tuning for right now. I told Jim that it was 80MM MAF calibrated for 19 lbers, but since I have the pink ones wonder if they are 21 lbers, and if that would throw my tune and MAF out of snyc??????

I have seen the pink top and yellow top injectors on stock 99-04 GT's and wondered when was there an injector change and wether they were rated different?
