Hi all i recently took my cosworth out for a drive, after around 30 minutes of driving at around 5000 rpm the engine seemed to die and the throttle wouldnt respond. I pulled over and the engine was ticking over as normal, but when i tried to give it some throttle it wouldn't respond, after about a minute all was fine again. The same happened again today. Any ideas, TPS? coil breaking down? any help please,

 

Look at map sensor

 

Would the Map sensor do this? Everything was ok until i put a autospecialist intake manifold on, no leaks, but i have had to Tee into the map sensor hose, for the dump valve, would this affect the map?

 

Check map sensor connections inside the plug, I had similar symptoms which turned out to be a broken wire/pin.
