Ill get to the point, my engine was doing the idle jumping. I have read the posts about vacuum, and some three letter abbrev. that I can not remember. Now my car is idleing at 2000-2300rpms (WTF), I have decided to leave this problem to the professionals. Here is the $1,000,000 question Where is a rotory specialist near Kennett, MO. I am 3 hours south of St. Louis and 2 hours from Memphis. Who is a respectable rotar head in my area. Thanks for the help.

 

Something (probably a vac leak, maybe a stuck linkage) is holding the idle speed way too high & the ECU is trying to hold it back down with fuel cuts.

You get a short cycle zoom - zoom - zoom.

A few years ago the Mazda advertising staff picked that behavior up & spun it into their sales pitch. (my personal assumption)

 

cold idle cam! mine is the cold idle cam doesnt drop for like 20-30 sometimes it doesnt! lol so i mean yea that could be it man!

 

Mine starts and holds an idle of about 2000 for around 8 seconds, then proceeds to drop and bounce between 1000 and 1300 until it's warmed up. Still dont know why it does it.

 

its the accelerated warmup system if u remove it im sure idle will proceed to normal..UNLESS its something else..

 

wher is it
mine wont stay started unless its warmer up and wen its cold it cnt hold the rpm at 3000 it trys to hold it at 2000 but it drops and cut off over 5seconds

do yuo think this is the samse problem yes its jumpy at arounnd1300-700 rpm
