missing at low rpm

Try not to dive it too much when this is happening, misfires can damage the catalytic converter $$! You will need to have the diagnostic trouble codes checked and then diagnosed to determine the cause.

Is the Service Engine Soon/Check Engine light on? If so a scan tool hooked to the 16 pin diagnostic socket under the dash should store valuable information in diagnosing the misfire in your engine. Could be as simple as a set of spark plugs or fixing a vacuum leak but it does need ot be investigated or it may result in catalytic converter problems down the line.

I am being told, wires replace 1st and then spark plug if it continues. Last result change the ignition coil.
