Ok, I recently started throwing code 13's, so I got an new O2 sensor (haven't had time to put it in yet) to see if that would fix it (ran rich for a long time, figured it needed doing). Before I could get to that, my problems expounded. Now, it'll flood every time I try to start it. I can get it going by adding throttle, but even if I get it going the first time, it won't want to idle and will die whjen you get off the gas. Now, if I rev it up some (2k) and then get off the throttle, you can hear some clunks or thunks as it drops. If I fiddle, it will finally idle, but at 450-650, and it will want to die. Soemtimes, it'll go fine, though...

Replaced 2k ago: Wires, Plugs, Distributor and cap/rotor, got timing fixed, CTS, VSS.

Even if it wants to die at idle, I have plenty of power and it runs smooth at higher rpms.

Any ideas?

 

Just threw a code 34 while examining the sound. Could this be a blown MAF?
