[updated:LAST EDITED ON 25-Mar-02 AT 06:08 PM (EST)]2.9l 1986 B2.. When i start my bronco it starts the idle at around 1800RPM and SLOWLY about 30-60 secs later, it will be steady at 1000RPM... No matter if its cold or hot. Even if i just turned it off and right back on. any answers would be appreciated...
thanks,
chaz.
Hey[br]
My B89II has done that for roughly two months. It also has the tachometer reading 1000rpm TOO high for a good distance. I've only driven in winter so far, I figure it has something to do with my cold engine, Im only 16 though
my b2 does the same thing has done so since i got itthe idle up duration does seem longer when cold but still does it when its warm out i have gotten a code on a air charge temp sensor before though i havent tested it lately. dont know if that has anything to do with it but its a place to start when it warms up around here
