No Power below 2k RPM
My 88 Fiero 4 cylinder doesn't seem to have much power till 2000 rpm +-. If you rev it a bit and let up, it drops rpms so low that it almost goes dead and sometimes does. When it doesn't go dead it recovers with eratic rpm, up to 2k, down to 500. Does the up an down 2/3 times then levels at 1k. Whe you press the accelerator it's kinda hesitant/doggie. Kinda like a bad carb.
Any thoughts? Idle Air Control maybe????
