what could be making my tahoe have a misfire

So does it miss at idle or driving etc?What codes if any do you have?

It does it driving and at a stop light when in park the rpm goes a little over 500 rpm then below 500 and lopes between them. It threw two codes p1345 and p1345 pending

Did you have the code before replacing everything?

I had it before I replaced the ignition coil

I would be following the trouble tree for that code do you have the trouble tree for that code?

No I don't. What is a trouble tree, sorry not to smart on this stuff so I will probably ask a lot of questions like that

Oh I took it to a shop for the test and they say my disributer is probably sticking

A toruble tree is a flow chart used to diagnose and repair of trouble codes or other issues cars and trucks have.For yours that trouble tree requires a advanced expensive scan tool to follow the trouble tree.I posted a diagnostic for your code that might help.Distrubutor sticking?Iam not following what there talking about.

I did not follow either they said it could be sticking and it is not hitting the points like it should, it kinda sounded like a scam so i did not let them do it. So by that chart seeing it gets better when i mess with the plugs, could I have a loose or busted ground?

On the trouble tree i see cap rotor distrubtor miss installed distrubutor loose etc.Also loose cam sensor bad crank shaft sensor loose wires to the distrubutor.Nothing about spark plugs for that code.

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?

Yes normally it will

Are the wires your moving close to the coils connector?

Yes I unplug it and plug it in couple times

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 www.rockauto.com you can get the part number and probably find that part number on amazon cheaper.

Ok thank you hope this works

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

Ok the problem ended up stopping and ran great since the last message now today I was driving down the road and it just died with no hesitation at all, now it turns over without starting

So did you ever change the connector to the coil?Also do you have spark?
