strange occurance
but, i need to add its happened before...sorta. after i did the headers and true duals, the car ran good for a few days or so with a small tune. and it started to back fire whenever i would go wot and sometimes at idle. resetting the computer fixed that. but this is different, it doesnt do it all the time at wot or at all at idle...only intermittantly after 4500-5000 rpms..
