check you ignition timing and DONT USE THE LOOP in the back of the engine.... mock up a makeshift inductive pickup with a plug wire between coil #1 and the plug in cyl #1

also try checking the TPS signal with a volt meter.... should sweep from around .5v closed to about 4.5v WOT (give or take .1-.2v) your pretty much looking for a random spike in voltage (5v or 0v) anywhere in the sweep

also could be the temp sensor to the ecu?
