whats up guys, I'm John, new to this forum and needing all the info I can get on my recent miata purchase. It's a 2000 miata special edition with the old style fm 2 link kit running about 6 psi. I am having VERY intermittent problems with misfiring under boost. No ck engine light, new magnecor wires and ngk plugs at .030 gap, compression good, also brand new coils from mazda. Whats left to check, auxiliary injectors? My afr goes way lean from time to time. There is no rhyme or reason why it does what it does. Sometimes it pulls great and sometimes it just runs like ****. Has anyone ever dealt with a similar issue? I know this is the noob thread so if I need to move it somewhere else just tell me where. thanks in advance

 

welcome

I'm in Simpsonville myself... Welcome aboard! Not sure about your problem though... I would post it up in the Prefabbed Turbo Setup section, and you should get some assistance...
