V6 grj120 gxl rough idle on low rpm
Hi I have got a possession of Prado 120 2007 gxl v6.
it had 190k when i bought it and now going 220k.
since I bought this second handed car, p0172 showed up for a while ( around 1.5 yrs not so often) then recently CEL comes up with P0172, p0175, p0420 and done spark plugs, 4 of O2 sensors, MAP sensor changed and the CEL gone for 2 weeks now.
since then, i have been noticing that when on ‘D’ positin while idle with A/C on, i can sense some vibration from engine.
Rpms are around 500 after warm up and once i start A/C the rpm goes +600 ~ -700 then engine are slight rough and once turn off, engine goes so quite. First I thought it was because of AC (probably) but when on ‘P’ or ‘N’ postion, engine goes very smooth even with A/C on.
With my short reserch, the problem could be caused from
ignition coil, spark plugs, o2 sensors, injector, AC pulley, belt… etc
Anybody had the same issue or any suggestion?
thanks
