Hey everyone, thanks for checking out my post
I have a 1999 v6 3.0L XLT Normal Fuel Automatic Ford Ranger with a #2 Cylinder Misfire. It is the only code that is coupled with a rough idle. The rough idle started right before the code was thrown, with a smooth history of running fine.
I have replaced
Spark plugs & Wires
#2 Fuel Injector
Fuel Filter
Ignition Coil
I have Cleaned and inspected
MAF sensor
EGR Valve
I have Conducted
Compression test - about #160 all around
Block test three times and passed
Vacuum test with starter fluid everywhere with no change
Check for any tubes out of place
The truck starts fine, and then immediately starts running rough at idle, which feels like a constant misfire. As soon as I give it some gas or get above around 2000 RPM the engine runs fine. Highway speeds seem to run well until I get around 50-60 MPH, and the automatic transmission shifts down, and it feels like it starts misfiring again. There is an audible click in the new fuel injector, and I have also pulled the valve cover and everything looks in place. I added fuel and Oil treatment which hasn’t done anything to change how the engine runs. I don’t know where or what to check next, any help would be much appreciated. Thanks for your time
