hey I was wondering if any one has had this problem. i have a 5sfe 94 camry and recently it has started stuttering, and i man violently. i have intake, nology wires, denso plugs, headers, exhaust, and a ecu upgrade. all the shops i have taken it to have not been able to find what the problem(s) are. i have had the o2 sensors all changed so that is not the problem. i did a tune up and that doesn't seem to help. i am taking it to one more shop and see what they say. i would like to get some feed back from you guys and gals. thanks
