Gonna make it slightly easier to resolve the matter.Little update here.Changed the fuel filter, car started right away but still had that miss at idle. So I decided to just stand in front of the engine bay and just listen. What did I hear? A whistling noise. Found where it was coming from. It was an extra vacuum line on the plenum (plenum came from an Automatic Cougar). I plugged it up with a plastic plug and RTV. well there was gaps in the seal. Took it off put a rubber cap on it. The car ran quite a bit smoother but still, have a miss and hanging idle.Also decided to change the oil and run some seafoam through it. Smoked like crazy for a bit, put some sea foam in the tank, hopefully that helps clean the injectors for the time being.The car overall, didn't change much as far as the things I did. I did the cheaper things first also they needed to be done anyway. I didn't drive it very far so I can't give accurate description of the differences at this time but I will tomorrow since I have a couple long drives.I'll see if I can find anymore vacuum leaks or anything. I'm going to get a tune for no cats ASAP so I can rule that out for anything.Keep throwing suggestions at me guys, Lee, I'll take those injectors. And yes my injectors are at 95% duty cycle... my zip is 92026. Tell me what the shipping will be. Thanks man!</blockquote>
