Multiple issues - gradual rough idle, various codes, ticking noise
Hey everyone, I've got a few issues that may or may not be related.
I let my truck idle for a few minutes, maybe 5+, and everything is fine for the most part. Then, it starts to want to die. RPM's drop from between 1000 to 800 all the way down to 400ish, and the engine starts throwing codes. Misfire in #1 piston, for example. The misfire code is not generally thrown, only this one time when it started to die.
Second, I just read a P0171 (system too lean) code while driving home today.
Third, there is a ticking noise, almost like what you would hear when electricity arcs and snaps, seemingly coming from the engine bay.
Recent work that I have done that probably pertains:
- Brand new Motocraft spark plugs
2003 2.3L Ford Ranger
