My car is done, but its throwing a misfire code for all 4 cylinders and idles all funky. Its driving me nuts. So far I've... Replaced the IACV, checked the Alternator - connections and checked out @ 14.5v. Tested the battery, adjusted the Idle screw, checked the mechanical and ignition timing, replaced dizzy rotor and cap, spark plugs and wires, adjusted the valves, my injectors are ticking...now what? Tomorrow I'm checking the the pins in the rockers to see if they're stuck and checking fuel pressure. I think it also might be an empty gas tank, cuz I can hear my walbro slurpin the last bit of gas haha. Anyways, any of yall got any suggestions?
