My truck stalled today. I just replaced plugs wires and air filter within the past 2 weeks, and it was running fine. I went and picked up a fuel filter today, and in the parking lot when I put it in park, the idle went down and almost stalled, then went back up. Then when I got home, as soon as it went into park idle went down and stalled. I haven't put the fuel filter in yet, but could that be the problem? I don't know when it was changed last. Is there anything else i should look for?

 

Bad fuel or your filter may be clogged

 

Did the CEL pop up? I assume it did. Have that read, and that will narrow it down more. Because it could be a lot of things.

Did you put the wires on the right plugs?

 

Alright, I'll get the filter changed asap. And I did one wire at a time. It was running fine while driving. Better then it was before I did them. I'll read up on the CEL. Thanks.
