A non genuine map sensor, from the land of dubious quality/ebay.
I assume you are trying to kill your engine ?, get a genuine known quality item such as bosch, or the 3 bar weber/mareli, whether this is the fault or not you don't want to be using it.
When you have got the 3 bar genuine article on there fit the bits but take it easy until you have been to a rolling road for a full load fuelling check, money well spent as it could save you a meltdown of the engine.
Before you do this though ensure you have rewired the fuel pump, and fans.
