I have a 2001 dakota 4.7L. Since my last oil change I have noticed it idles fast and pulsates from 1-1.5 RPM for 30 seconds or so and then drops to normal idle. Can anyone give me suggestions as this just started.

Try cleaning the throttle body and IAC motor at the bottom. Another possibility is the TPS sensor needs replacing.

I HAVE THE SAME PROBLEM, BUT IT ALSO HAPPENS WHEN I PUT IT INTO PARK. ALSO, THERE IS A DINGING SOUND, THE KIND YOU WOULD EXPECT TO HEAR WHEN THE GAS LIGHT COMES ON. THIS HAPPENS AFTER THE VEHICLE HAS BEEN RUNNING FOR A MINUTE OR TWO. ANY THOUGHTS?

Hi all , I know this is an old thread, but i
have been experiencing a slow oil pressure
gauge since my last oil change in my 2004
Dakota 3.7
I was a little worried about this so i have
been searching the forums.
However i think i have stumbled on to
something.
I always use 5w-20 oil with a quart of Lucas
oil stabilizer and i would aways buy the
Walmart brand oil filter.
So after the last oil change i noticed the
slow oil pressure needle rise. it takes about
a full 6 seconds now, whereas it used to rise
to full pressure in about 1 second.
Well after checking everything out the engine
and oil is fine, the sender is fine.
I finally stumbled across some information
about walmarts filters, it seems they used to
be made with a true spring bypass valve but
walmart has changed venders and the bypass
valve is gone. So i went to wallmart and
grabbed one of their SuperTech oil filters and
looked up inside of it and sure enough, the
bypass valve was gone. it may have a bypass
system in it but the actual valve is gone.
Which makes me wonder if there is a correlation
between the sudden slow rise of the oil gauge.
