pajero rough idle

Post by threeleggedfork »

gday fellas,

i think there is somehting wrong with my idle on my nf pajero. its a 2.6 4cyl shorty with the carb, and the idle keeps playing up. when i was driving, and pulling up at lights, it would keep surging between 1000 and 2000 revs in a repetative manner, and i took that to a mechanic and he fixed that, but then after work i tried starting it and it wouldnt start because it couldnt idle, and would 'conk' out, so i tried giving it revs when it started and it was fine. it also shudders and shakes really violently when it shuts down, could anyone tell me what is wrong?



cheers. and merry christmas!

to test, just disconnect the hose and block it off, if the engine runs ok then replace or clean/soak the pcv valve in petrol
