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?

oil on the plugs is an indication of worn engine and ting problems
you can use a a hotter plug to burn off the oil or use multi point plugs to that they don.t foul from the oil

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 .

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.

Do you know how to test electrical circuits ? Is the PCM - engine computer controlling the coils ? Test with a test light ! One side has B+ voltage the dark green with orange stripe wire ,the other goes to the PCM , which will suppy a ground when triggered . You can test this with a test light . or you can buy a noid light at the parts store . If you replaced the coil an spark plug an that code comes back ,could have a burnt driver inside the computer , test it first !

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
