E30 Zone

Hi i recently fitted a m50 inlet manifold to my m52 2.8, right hear goes i modified the m50 manifold to take the m52 icv thing so it fits the same as the m52 one, this worked fine all be it a bit tricky. Then i made up a throttle body plate this works fine. One the car is started it runs fine up untill the temperature gauge gets half way to normal opperating temp, then when you let the revs drop the car will cut out and stall ( it will start fine straight after). So i took the oil recirculation valve off and this was full of 5h1t so i cleaned it and all the hoses, still no luck tho. Im 99% that there are no vacume leaks. Any help would be great
cheers mitch

What TPS are you using?

Is it running rough before it stalls or is there any loss of performance?

hi im using the 328i tps brian and i thought about trying the 2.5 tps, and theres no loss of performance.
