sa15cr Posted October 27, 2014 Share Posted October 27, 2014 My glanza done the same and I changed plugs, plug leads, rotor arm and distributor and made no differences so then I changed fuel filter and run injector cleaner thru it and seems to be ok now Quote Link to post Share on other sites

Sefton-EP91 Posted October 27, 2014 Share Posted October 27, 2014 Mine done exactly the same and turned out to be leads. I understand you say you had ignition overhaul but does do exact same as mine did. Quote Link to post Share on other sites
Flaminsam Posted October 28, 2014 Share Posted October 28, 2014 Mine misfired like that, turned out to be the coil pack split. Mine started misfiring at about 8psi of boost then just got worse from there Quote Link to post Share on other sites
