Hi gaurav

thanks for your reply. Actually i did not see any swing on the rpm .its strange . When i put the shifter in to D rpm comes down around 700 and down very slowly comes down to 630-640 after 5 min in to the D and my food on the brake pedal . Than i put the  car in to the N and rpm comes to 780 and after 1-2 min slowley comes to 890 and then 910 stop. By the way do you think is that related to TPS adjusment. Because the mechanics played with that one time 6 months back. and i believe all problems come from that time. I chacked the voltage of the terminal 3 and ground it was 5.01 or 5.02 and continuity between terminal 1 ground and 2  when the throttle is close completely its discontinuous,(no beep )on the voltmeter.  but when i touch the throttle to open it very very very slowley ( its like touch )  its continuous and complete open is discontinuous.  Is that correct? 

Again thanks 

Hello friends 

well i changed the icv. But i found another problem. I cloesd the air screw completely but engine rpm stay around 910 and when i put it in the D comes around 650-700 and after 30 min driving comes around 590-610 almost and when i put it back to the N engine search to find the right rpm and comes up like 870 till 910 . But its strange ? Becuse i closed air mixtuer screw completely. Today its makes me tired . Becuse as i know the air mixture screw should be open 2.5 turn. So when rpm stay around 690-700 i turn the screw a little like 1/2 turn to reach 850.  But when i switch off and again turn the car on rpm goes around 910-20 😖. I also change the o ring of icv and remove the battery negative for 5-10 min . So what do you think.? 

Hi gaurav

thanks for your reply 

The ICV will reach on Thursday.so i will update u by friday. By the way, one qustion what is the exact adjusment for air mixture screw ( air bypass screw) ? 

Thanks again buddy.

dear friends 

thanks for your quick answer.

well. when i turn the steering wheel the RPM goes up very gently and also when switch on the AC. RPM goes on 930-940 . but after 1 hours driving in traffic engine voice change to like a mustang  and rpm is come around 550 - 600 also when i came to the  home i opened the hood and turn the air screw a little bit open to increase the rpm . but i open it (1 turn) to reach to 800 and tomorrow morning when i turn on  the car after idling rpm stay on around 960- 980 and again i turn back the air screw to where it was. and rpm comes to 900. so if you believe that the icv has problem i will change it. but i feel there is some problem like the ECU delay or like this. be cause when i press the gas rpm goes to 4000 and release it rpm comes to 1100 and then engine try to find idle around the 920  and when shift the gear to D rpm comes to 810. i thing engine is dizzy. 

Hi friends. Actually i have 2 problem which is on of them is same. By the way i have pajero 3.5 v6 24valve 6g74.

1- i have engine vibration on the idle. I checkd the engine mounts . Timing belt and also timing. Spark plug and wires changed . Oil changed . Vacuum leakage  checked by splashing water around the manifold. Fuel pump checked and also the injection parts got clean. But still i have engine vibration at 700-850

2- after one hours driving  engine start to lose the rpm to 550 even 500. Also in traffic jam is horrible . When the gear is on D rpm reach to 500 but all these problems comes after 30 or 1 hours driving in the  Traffice . Your feeling is like the  car lose the power. But in the highway no problem. 

Also i clean the icv valve and throttle body.  EGR . I get tired i dont now what should i do. Becuse i cant stuck down in the traffice also i afraid  to use the AC on the Traffice. Because when i get more load from engine i lose more rpm.
