Hey everyone, new here to this forum after getting my Ranger in August. 2000 v6 3.0 4x4 Manual extended cab
. I bought my truck with 143k on the clock and was in great shape, recently passed inspection and full maintenance records from previous owner. Flushed all fluids, new brakes, new IAC valve, new plugs, and a few other things with my dad who is an engineer and a super mechanic type. I have always done basic things like oil change etc. growing up, but really trying to learn my engine since buying my truck.
She had been running like a champ and a few weeks ago around 149k i noticed this chirping noise that sounded like a belt. Did my homework here and around the internet and found it was the camshaft synchronizer and sensor. here's a video of the noise

I know there a million threads about camshaft syncros, my issue here is since replacing mine
now, I got a new duralast gold camshaft syncro and sensor from autozone for $35, and carefully swapped it out making sure to replace the new one in the exact same position as the old one i pulled out. truck started right up, no more noise. but now I am idling around 1300rpm. it will come back down eventually to around 900 when i am fully stopped at a red light, but stays up at 1500 if I am driving and coast in neutral. No check engine light or anything, I took it to a mechanic and the computer didnt give any codes or any indication anything was wrong. Went out of town this weekend and put 450 miles on it since changing the part, mechanic said this was ok and high idle would just cost me a little gas.
But now I'm back in town and want to get this sorted out and get my idle back down to the cool 900rpm she used to purr at. Is my timing off? Do i need to redo my camshaft sync positioning at TDC?
