Bigdog how are you?
It sounds like you had a real amateur working on Max.
You should know that the car has a special amplifier (Hitachi?) which was specified by Unichip. If you need a new one contact Graeme Cooper. It is located under the air cleaner at the back of the LH flat section of the mudguard.
The coil is a 717 solid state and you have a spare in the bits I gave you.
however I doubt that this is the problem.
The TPS conflict may be an old code as for some time the TPS wires were disconnected as the join in the wires had separated. This may have happened again with the mechanic. They had to be lengthened to fit the position on the Thor manifold.
The test is whether the injection cut off works over 1500RPM. As you know by a previous question it is quite noticeable. If the TPS is reading correctly the injection cutoff will work so give that a check.
Maybe there is a fuel pump problem or simply that the fuel is old and has absorbed some water.
