driving home the other day I went to down shift to a stop (manual trans) between shifts the truck would idle way down 200 rpms and then surge back up. (Normal clogged filter diagnosis) got a lil worse on the way home. went from barely noticeable to the point that I struggled to keep it running at an idleing stop. Changed both of my fuel filters and had heck starting it. (rare for me) So I tried a gas rag... would fire on fumes but wouldnt prime. cracked lines went through that process etc. nothing. so I had a buddy pull me. finally started after a whopping 3/4 mile. then died shortly after. popped clutch again and fired up. drove 2 or 3 miles pretty hard. ran good 3/4 throttle, very smooth and no sputtering until I would take my foot off the pedal. it would try to die. (sorry for the long story btw) any ways, got back home, took the filter off the side of my frame (not factory) and replaced it with a working holley blue. hooked it up to "key on" and now it will start on a gas rag but idles EXTEMELY ragged. very wild lope. almost dies and pulls itself back up hard, blows lots of smoke when the RPMs rise during this lope. I do still have my stock lift pump in working order where it belongs btw. never had any problems with it. either if I gradually accelerate or floor it it pops and crackles blowing suit wads and smoke rings out of my stacks. brown smoke, gray smoke, white smoke etc. I have great fuel comming from the tank to holley, from holley to lift pump, and lift pump to VP. This scares me. the closer I get to the engine the higher the "fix it" bill gets. NO CODE out of ordinary thrown though... big question. I pray that there is an electrical somethin or other I have over-looked... Cause I really dont want to point my finger at that VP.... Please, any helpful advice/comments will be greatly appreciated. thank you, Cody (sig is up to date)
