I changed my spark plugs & wires and now the check engine light is on. We took it to auto zone and had it tested and it says that it is a cylinder 4 misfire. We made sure that everything is tight and tested the power pack and everything is fine. Now it also feels like it is going to stall what can I do to fix this problem?

take it to auto zone check again.

Code 1105 is for a solenoid valve that controls the MAP sensor or Baro sensor.
The solenoid valve would need to be tested.

It will reset on its own after several drive cycles or you can take it back to autozone and they can reset it .

All I am getting from your discription, is that you
have a code & a misfire ,you have yet to diagnose.

Except for replacing the wires, that should last the life
of the car,your doing okey

You now are embarking on throwing parts at it,
not diagnosing.

I can't tell you how to continue,as I don't know
if have any test equip or skills required.

You may have a bad ignition module or other
issues

Again,test,don't install 1 part,unless something
tests bad.

start with plugs get to a dark place start truck if you see sparks replace wires if not replace coil

I would check for a cracked distributor cap and or bad rotor bug in distributor.

Instead of the auto-zone trip , take it to the dealer !

Should be able to get a new one, can't you? Or call around to the auto wreckers. Should be lots around.

yes i would change the plug wires , you can take a spray bottal with water and spray that wire, and if it starts to run real bad then it is shorting out, you may also have a injector going bad you can test this buy puting a ohms meter on it and ck the ohms it should read the same or close to the same as the other if not it will need replaced

This is a random misfire......change/check your spark plugs and wires
