WHAT COULD BE MAKING MY HAVE A MISFIRE

1999 Chevrolet Tahoe • 113,000 miles

I replaced the plugs and wires disributer cap and roter. The ignition coil has been replaced but was not mounted for a little bit whenever I messed with the plugs on it, it ran better for a little when I turn it off and start again it misses again.

Sorry I did not specify I thought the worn wires would include the plug for the coil, the one that powers it not the lead to operate the disributer

So if you move the coil feed wires around it changes the way it runs?

You said the coil isnt mounted?If thats true bolt the coil down tight and see how it runs?If you can still play with the plug and change the way it runs replace the connector to the coil.

I recently mounted it so I will try that do I just splice a new plug on or run a whole new wire

Iam sure you can get the connector with leads i would replace the connector with leads thats your best bet Look at http://www.rockauto.com you can get the part number and probably find that part number on amazon cheaper.

You have to start with the problems that you can find like that one and go from there.
