I got all the work done on my car today. Rear diff bushes and seal/diff oil change, trailing arm bushes, front left axle boot and a full service. The possible culprit of the rough idle could have been the air filter, it was munted!! absolutely had it.. Scan tool went on with no error from the air flow meter... It's too soon to know if the idle is still an issue but will monitor it in the next few days. Will it take some time for the ECU to adjust to the new air filter and correct the fuel ratio?
