3.0L runs rough when warmed up
Howdy Y'all recently run into a problem with my 92 3.0L v6. It bucks and misfires after the engine warms up and occasionally dies. It idles great and runs perfect when cold.
I have replaced
-fuel pump
-fuel filter
-fuel regulator
-maf sensor
Any ideas? I cant seem to figure it out. Possibly something with the erg valve? any advice I could get would be greatly appreciated. thanks!

1992 3.0l still used distributor and TFI module for spark.
TFI modules often became heat sensitive as they got older.
