Hi all,
I have the painful rough idle and low engine speed miss when driving issue on my MY05 Liberty GT. I took it to All Drive Subaroo and they found it was running lean and compensating continually hence the feeling of a miss. They suggested starting at the fuel filter. I did that and it made a huge difference. The idle improved a little, the low speed miss (below about 2500rpm) was gone except when the car is cold. Before I couldn't take off and be confident the car would actually go, I now can which makes driving a lot safer trying to pull out in to traffic. When the car is cold unfortunately is does still miss and hesitate to take off below 2500rpm, but this soon goes away with about 1km of driving. The rough idle remains sporadically.
So the next step was to have the injectors removed, cleaned and refitted. It made the car run perfectly for about 3 days, it was like it was brand new......then slowly it started to go back to it's old habits. I have noticed that the colder it is when the car first starts, the worse the low rpm miss is.
So I am now looking at replacing the injectors. I would rather stick with the OEM size as then I do not need a tune. But finding them aftermarket is a little hard.
Does anyone have the OEM injector part numbers?
Or failing that my other path is a different size and a tune, does anyone recommend injectors and what he part numbers are?
Thanks in advance.
