Rough idle and stalls while driving
Hello all,
I have a 2004 ford ranger edge 3.0 V6 that has given me and a few mechanics the same issue. It idles rough and occasionally stalls while driving. I have replaced the MAF, idle air contoller, fuel relay, and fuel pump. Issue still exists, my next replacement item is the crank angle sensor, but I am not sure what it does. Is there anything else to consider?

I already had it scanned at AZ, nothing hit, battery was putting out good voltage and alternator was the same, no CEL is showing. I cleaned the MAF and replaced the TPS, it worked for a little then the MAF failed and I replaced it. Took it to a shop and they found a burnt relay for the fuel pump, which was replaced. The truck ran fine for a month then the issue came back, so the fuel pump got replaced,thinking it was a fuel problem. Just drove it for three days and it stalled out again. I'm beginning to the think that there might be a problem with the the fuel injectors or ignition coil.

Saw some damage to the coil pack and replaced it, engine sounded good on start up but quickly stalled during a 5 min drive. Mechanic took a look and checked the inertia switch, tested bad and had it replaced. So far it hasn't stalled, but the RPMs sometimes drop when the vehicle has stopped. This usually happened prior to the stall. Waiting to see if the inertia switch was the problem.
