Have I missed anything.

Right as most of you know I'm coming to the end of my conversion but I have a niggling issue which I'm trying to get to the bottom of.

The car has developed an over fuelling issue. It idles ok but when you rev it pops and I have black smoke. And when you try to drive the revs just die. I ran a diagnostic check and it highlighted 3 codes, 1) short/open circuit in map sensor 2) open/short circuit in coolant temp sensor 3) excessive boost pressure. Having checked all the wiring and plugs and the coolant temp sensor is new. I reset the ecu and now there are no codes present. But I still have the issues. My temp gauge doesn't work either not sure if its related or not.

Can anyone think of anything I've missed or overlooked?

I had a quick look at the n/a wiring diagram and I'm not sure if the gauge works in the same way but there is 2 sensors to run this. So I'm not sure if I'm missing a sensor from the thermo housing as I only have the coolant temp sensor and the fan switch.

Any help appreciated as the sooner I get this sorted the more chance of it making Japfest.

I'd try another map sensor on it. I had the exact same issue and it was a faulty sensor. I can send you one to borrow if you want? Try it on and see if it changes anything?

as above id say map sensor it would account for 2 of the codes. sounds like its reading more pressure than there is so its pumping in a tonne of fuel

I still say try a map sensor Rob!
