My 305 is running like crap again. Ok heres the deal. About 2 weeks ago I wanted to conquer my engine running crappy problems, so I Checked the timing (good), Changed all ......spark plugs, New distributor cap/coil/rotor(was old and crappy), Checked firing (good), checked compression (good), Fixed a vacumm leak I found (T-fitting broke) ETC... Well after I did that I was stoked because the engine seemed to be running pretty decent. Well that was until today. I started it up and it sounded fine, but as soon as I took off and tried to give it gas, it would completely "bog"/ "lag" out, NO power whatsoever.I even try to give it full throttle, and NOTHING happens... So I drive it down the street (not able to go over about 15 mph) and pull over. I shut the engine off, and check everything out, (everything seems normal too me). SO I start it back up, and still doing it just as bad. So I give it full throttle again to see what happens ( ) And it lags/ "bogs out" for about 2 seconds and then all the sudden kicks in and takes off.... WHAT THE HELL IS GOING ON?!!??! I am trying to get this truck running decent so I can start lifting/modding the thing out, but I want the motor to run good before I dump all that money. Someone please help, I dont know what else to do . I need a good hint on what to do, or even better, I need an expert to come check it out! Thanks.
