Hi,

I have got a S1 RST that is running OFAB management, however I have a few problems.

If the ISCV is plugged in it starts fine but idles around 2500rpm, if I unplug it it idles around 1200rpm, but is a pig to start.

If the map sensor is plugged in, the car will run for around 2-3 seconds then stall, I can hold it on the pedal but it misfires and over fuels excessively. However if I unplug it, it runs alot better, but still not right. First I thought the map sensor was faulty, so I brought a new one, but it hasn't made any difference.

I've checked all the earths etc and all seems fine, but running out of things to check now.

Has anyone had a this problem? or any ideas on what to check?

Thanks
