pj027235 10 Posted April 2, 2016 Right peeps, I have read that by connecting a digital multimeter is series with the DPR and adjusting the 3mm idle mixture screw in the MAF housing one can set the correct idle mixture. My questions are; How accurate is this? and Is it as good as using an exhaust gas analyser? Caveat, So far I have not adjusted anything or removed the tamper proof seal.
