yeah ive searched Still cant find the right answer

I got one problem with my car ... the car revs up and down from 900-1500rpm with old ecu and with pfc Ive changed my sparkplugs,oil,thermostat . Any one who know whats making it so unstable? My mods are pfc, open airfilter, catback 1994 R2 24000km. Car boost perfekt and runs great! And the idle changes when i put on a/c or light's.

Thanks in advance!

Did you do the PFC idle learn process?

 

yes mate, 10 min without a/c , 10 min with a/c, 10min with rearwindow heatning. I got in done mapped from Jason, for my mods.

 

I don't have a PFC but I know for your accessories...your idle RPM will only be a few notches higher when you have your ac/lights on because you have more accessories on. Normal on any car. But it shouldn't jump dramatically. I guess the PFC can learn (^) it as stated above?

 

Its revs from 900-1500 with nothing on "ac light and so on" and 1000-1300 with some stuff on "ac and light" Me and bro "hes a mec" have checked allmost everything, cant find a shi.... Non of us are rotor mecs And the closest rotorshop are 2500km away and are not avaible until desember waaaaaaa why dont i live in USA :[ where everything is cheap "compared to Norway"

 

idle bleed screw?
