2001 MPV. Was missing and hesitant to go when accelerator was pressed. Diagnostic code showed missing on cyl 3, so changed plugs and wires.
Drove OK for couple of weeks then suddenly it is slow to accelerate from a stop when accelerator is pressed. It seems to respond better when less pressure put on accelerator; in fact if you push accelerator too hard RPM increases to 4k, but there is no real increase rate of acceleration.
Once it is up to speed, car seems to run better, but still not responsive if you try to accelerate at higher speeds.
The car also loses speed as well as RPM when going up steep hill. It is still unresponsive when you press the accelerator a little, but when depressed more the RPM jumps to 4k with little increase in speed.
The check engine light is not on, so I am not sure if a diagnostic tool will pull a code.

You can get error codes without the light coming on. Have it coded again.
