What year supra did they start using coilpacks in the 2jz-gte?? Reason i ask is because when i was looking up oem parts for my 94 supra TT 6 speed the parts guy said i would need spark plug wires. I don't have a distrubutor i have coil packs. Does a obd1 or odb2 ecu use coilpacks?? I recently just bought the car so thanks for the info in advance!!!
