Hi Ranger buds. Ive just recently purchased a 2001 v6 4L truck has been running fine up until a week ago when i started feeling this jerking while idling at a stop light. No problem on take off and It doesnt feel like ive lost any power. The truck still drives fine other than shaking for a bit when starting up (occasional) Any insight would be really appreciated.

 

 

Welcome to the forum

I assume an automatic transmission?

Yes, clean IAC Valve, info here: https://www.explorerforum.com/forums...-w-pics.84220/

And also clean MAF sensor, once a year, this one is very simple to do

The 4.0l SOHC engine is what you have in a 2001 Ranger, and the older 4.0l OHV engine(1990-2000 Rangers), eat spark plugs
They have a larger gap, 0.054" and need it, but this also means a hotter spark so best to use Motorcraft or Autolite spark plugs if available
And use regular copper or Double platinum, never single platinum

Point being it might be a good time to pull a few easier to get to spark plugs and have a look at the tips, see what engine condition is on this new purchase

 

I ended up thinking it mightve been the fuel filter went ahead and changed it out and the truck runs so much smoother but ill go ahead and change and or clean what yall have advised me. Thank ya'll again for the help.
