Number 4 mis-firing

My trucks check engine light came on and felt the loss of power, went to autozone and they ran a check and told me it was my number 4 not firing. i bought a new boot and plug on the way to work. When i started it tonight ran just fine until motor warmed up then it began misfiring again. was wondering if this sounds like a boot or plug? And how much should i be paying a local shop (not a dealership) to change them both out for me? Thanks

If the check engine light is still on, take it over to autozone where they can pull code's out of it for free, and get back with us here at FixYa so we can help you with your trouble code, if the light is off and it's now running fine don't take it there because every thing will check out good, the light has to be on to test, if it's running fine wait till light come's back on, if it does.

Engine shakes and can not accelerate as quick when starts

If the engine light is on, a code scanner needs to be connected to it to find out why the light is on. It could be one of the sensors causing it. Take to autozone or advanced auto if there is one near you, if not call a repair shop that can do it. Autozone and advanced don't charge. Takes about 30 seconds.
