Car in sig, well it use to idle all the time at about 1100 and 1200 but now its droped? how could i change the idle???

 

Is it stumbling or anything? My car car idles at 700-800 and it is running fine. My 93 used to idle at about 1100-1300 and that was cause it had a couple of problems. Did you add or remove anything before you experienced this?

 

some time it stubals when i slow down at a light... umm it broke down about 3 weeks ago the ignition modulator went out, nothing major but it seem after i put the new one in lower rpms and take offs from a stop. plus when i first start it and in Netural it idels at 1100 to 1300 but i think it use to idle at 1,000 to 1,100 all the time

 

my 2.8 with 100,000 kilometers, (70,000 miles) idles at 600-700 rpm after its warmed up if its cold it starts at 1,100 then drops.

it runs fine.
it shouldnt stumble at this rpm range, you may want to do a tuneup

 

On my 92' I had a long time ago, it idled around 700 - 800. I think thats pretty much normal for most cars. However my 94' is having some problems with its idle

 

Chilton's manual says
'' 1988, 2.8L, ignition timeing 10* before TDC, 700rpm idel for auto and std. trans."
Thats for when it's all the way warmed up.
So your idel is high.

 

mine is idliing around 1000 1100, someone above said thiers did that but it had a few problems, what were they and how do u fix them?

 

I had a 91 RS 3.1 several years ago, but if I remember correctly it idled at 700-800 RPM. So no need to worry.
