wmburns: I have cleaned the maf appropriately multiple times and even pulled and installed another maf from the local pick-n-pull w/ no changes to check engine. I have not checked the fuel pressure regulator, but it is connected to good vacuum. I'll pick up a fuel pressure gauge tomorrow and check it out (thanks for the psi #'s). Thanks for the recommendation for the injector cleaning, I just bookmarked them for future use. Unfortunately, I did not see your post until after ordering the new fuel injectors from american muscle. I know that two of my original oem injectors were not firing (clicking) when connected to a 9 volt battery, that is why I ordered the ebay set. Do you think those injectors' could have been brought back to life by InjectorRX.com? I am pretty sure these 8 new accel injectors will solve my problem. A little pricey (though cheaper than oem), but the 100% 5-star reviews on the 19 lb. injectors sold me on them.
