Welcome Visitor! Please take a few seconds and 2007/ 4.0/ Ford Ranger misfires cylinder 1,2&3 after warmup
.
Drives fine when cold. Slight reduction in power. Misfires only at idle. RPMS at idle drop to 3-400.
Starts to smell like sulfur.
When cold, no smell, idles at 5-600 rpm.
All new plugs / wires / injectors/ MAF/ IAC Solenoid/ Fuel filter and bank 1 upstream O2 sensor. ( was reading stuck high- that code gone now. )
Only codes P300,301,302,303.
Totally fine at any speed except idle. Looking for most likely culprit based on someone similar experience.
