DMARK 0 Posted March 4, 2014 Report Share Posted March 4, 2014 Hi guys as titled I have a 02 4 motion in which started off as a small hesitation at low rpm and now has no low down power at all, no fault codes at all apart from one in the abs controller which just said ecm connector. After spending weeks on it I'm now stumped. Ive checked absolutely everything in mvb's and all readings are good, there are no air leaks and the cats are in perfect condition albeit white and a bit too clean which would suggest a lean mixture. All ignition coils, fuel filter and air flow meter are new. The car starts and runs perfectly with no misfires. Any help would be appreciated Link to post Share on other sites

DMARK 0 Posted March 4, 2014 Author Report Share Posted March 4, 2014 On idle or whilst driving? Strangely enough it only lets me read data through basic settings I'm using launch x431 master with the latest update Link to post Share on other sites
UnitedMotorsport 55 Posted March 4, 2014 Report Share Posted March 4, 2014 Either it doesnt matter. Basic settings is not the right thing to use. Link to post Share on other sites
