Ok so here the down low I've been trying to get my Ka running I have tired everything , it will start up everytime but it won't stay running with the maf plugged in which means usually the maf is dead but I've tired three different mafs I even hooked up a safc2 and plugged in my z32 maf still the same thing and when its running without the maf the rpms fluctuate through 1500 to 3000 rpms as soon as I plug the maf back in it dies so I'm a little stuck on what the problem is here's the following mods and replaced items so if I could get a little bit of insight as to what the prob could be ( timing is dead on the marks ) so it shouldn't be that dizzy is where it's supposed to be I don't have any vaccum leaks or mani leaks I checked with starter fluid I've even swapped out ecu's :wtf2:
