I chnaged my plugs, wires, and airfilter at the recommended mileage. It is factory recommended parts.

The starting has changed.

Before ..... one turn and it would start hard and strong. Now it turns a few times and fire. The idle in both cases resume back to normal.

I have changed oxygen sensor on another ocassion. The analysis machine does not read a problem.

Check the fuel pressure-if okay start with the coolant temperature sensor-this the one that tells the computer the engine is cold needs fuel before the oxygen sensor takes it over during closed loop mode-
