They all run a little lumpy , it's a F4R characteristic

Lol ,but still on what rpm your is in idle
Even if you are not sure how it is in numbers so just say where the needle is located ( like mine higher lower ... )

My 197 on cheap fuel used to idle like a pig, up and down between about 800-1100 rpm but on v power it ran as smooth as anything.

What fuel are you using. Some cars don't like cheap stuff.

98 octane ( my idle is extremely stayable) just the numbers move like every other car ,its never stay at same number
All i was saying is i think my idle is abit high (50-100 rpm maybe ) not sure at all

you will never get a steady reading with an obd reader - its too accurate/sensitive

the engine ecu is making millions of calculations and adjusting settings many times per engine rev

idle speed of 800rpm give or take a bit is fine

That looks about normal once the engine has settled down after start.

Fano ,the funny thing is i think since i cleaned the throttle body the idle revs went up and not the opposite
( just saw a picture of my idle 2k km ago it was under the line(750-780-+)

maybe pull out the spark plugs and check the gaps. after i changed my plugs my idle changed to bang on 850

 

[Legend@wheels]

Uhmm worth a check .
i changed mine too 4 months ago
if its from the plugs maybe it will be steady soon automaticaly .
Anyway cant see how it could harm the engine or anything else [emoji5]

Picture looks like absolutely normal idle when warm.

 

[Legend@wheels]

I will be thank full if youll check later yours when its on its operation temp ( 10 mins-+ after start ) its around the last line before the 1 for sure but above ,on it,under it is what interested me .
Thx

Mine from obd reader have 800-860 rpm idle on hot engine, is that okay
It seems to me too big difference between min and max values.
