I have a 01 dakota 3.9 2wd an it has a random forward advance or hesitation that only happens after sitting at a light after about 45 seconds.It never happens on short waits at lights an never in park.It isnt a everytime thing either.Ferls like truck want to move forward a tad.i replaced plugs distributor cap an rotor an the plug wires are new. I cleaned out the iac too an fuel trim readings are fine...went thru a few tanks of gas also..What else should I look at?​​​​​​​is this a timing issue? Thanks​​​​​​​

 

Timing is purely computer controlled. So, not user adjustable. Did you reset the computer after the maintenance?

 

Ill reset it .An see what happens

 

do you mean it's trying to creep through the brakes?

 

I feel that forward arc like .. ..an slight forward move

 

I have had this happen too also a 2001 Dakota but mines a 4x4 the first time it happened I thought someone bumped into me from behind but no one there I was thinking it might be my torque converter locking up anyone have any ideas?

 

I reset the ecm added some seafoam to tank an so far im not noticing it..I think the reset helped..Maybe that rotor that looked a bit worn an flimsy factored it too..Ill know after more sitting in traffic .I dont know if torque conv is a factor as your sitting at a light but am curious also on it.

 

Did it again....random...
what next?

 

Mine would do weird and strange things, but, it wasn't an engine problem, it was a trans problem.... dropping into neutral at stops, then BANGING into gear when I stepped on the gas, and various other annoying habits. Changing the trans electronics fixed mine....

 

Why , when it does do it, is it only after around 30 or 45 seconds? In drive fully stopped.
