Hi everyone my names Andy am new to the site. I have a 1990 Mitsubishi Triton with the 2.6 4g54 enigne. the problem is when i start it from cold it idles around 3 thousand rpm then once warm it will go back to normal.Any ideas of what it could be would be appreciated.

if carby its a choke setting

if injected... sounds like TPS (throttle position sensor)

its a carby, how do you find out about choke setting?

Mmm a big 85kw Carby 4G54.
As far as the choke setting goes, I have a feeling that the choke is controled by the cooling system. You may need to pull it apart. (I always tried to stay away from Carbys during my apprentiship)

dont know if the triton had the samr carby as a magna
