Assalam u alaikum guys, hope everyone is doing well, my Mitsubishi Pajero, 1993, 2.8 diesel, manual transmission, with 203k on the odo has been giving me this new problem lately ever since I had her fuel filter and gear oil changed, as soon as I rev her and let go of gas, the idle comes down, the car gives a shudder (kaanpti hai) vibration and then idle becomes smooth, it happens also between shifting gears. It's driving me crazy. Oh and when the AC is on, the issue doesnt happen, the idle comes down smoothly and all. If anyone knows about this, please help. JazakAllah
