I have a 95 Honda Accord EX 2.2 Vtec. 4D
120000 miles

It sputters at low RPMs, while under load and backfires out the exhaust. Its fine at an idle. Cylinder number 3 seems to be misfiring.

I've replaced the plugs, wires, dist. cap, rotor, fuel pressure regulator, O2 sensor, and injectors.

The compression on all the cylinders was the same(cannot remember what it was exactly).

Anyone know what it is? have similar issues?

Thanks,
Drew
