please help!, 90 carburated wont idle and dies
Alright it is a 90' pickup carburated 4 cyl 22r, what it does is start up and run extremely rough, sounds like 3 cylinders are going (like maybe a fouled plug), what it will do is start run at fairly high rpm for maybe 3-4 seconds (could be choke) then drop down and die unless I give it gas, I have to continually pump the gas to keep it running and when I do give it gas the way it feels is like the engine is spinning really fast, like a winding sound if that makes any sense, I have tried to keep it running to warm it up and see what that does but nothing changes.
at the times leading up to this: it started doing this when I let my roomate move my pickup in the morning after it had not been started in a couple of days and he rodded on it w/o any warm up, I went out there later in the day and it would not idle correctly, I changed the cap and rotor, spark plugs, ingition coil and mount
if it means anything the engine in it right now is a motor swap that was never correctly timed (drivable but jerked through some rpms) and it fouled plugs regularly when I got on it
let me know if you have any ideas, I need to get this thing fixed or sell it for parts quick, thanks
