I have a 1999 ranger 4x4 4.0ltr 5spd and it idles fast (between 1500 and
2000 rpm) for 10 seconds or so after clutching it at stoplights / stop signs
Theres not much consistencey though, it idles high at different rpm for
different lengths of time every time, before eventually settling back down
to about 800rpm. I have owned it since November and its only started
happening in last 6 weeks or so. It is of course all computer controlled so
I carnt adjust anything myself.
The question is - is a normal thing now that the weather is warm or should I
take it to ford and spend a few hundred bucks having them read fault codes?
thanks in advance for any help
