check your spark plugs/wires, then make shur there all plugged in, check you coil pack harness wires because mine melted on me and i had to rewire it, check and little hard for any vacume leaks, test your igniter, because it really sounds like your missfiring.

but your timeing if i recall should be 15 i think, dont take my word im to lazy to look at the motor in my garage, but the 2nd marking from the left is the one you want it at.

also check you cam position sensor wires. mine where melted there, although i was just getting a code 14 and 52, but it ended being the coil pack harness, i mixed a power and ground, its hard to make out them damn faded colors, there green then barley lighter green, then another green.
