Hey guys, have a bit of a project l200 Mira I acquired a little bit ago. It has had the Franken motor 850cc block with 660cc efi head swap already done to it. I have a bit of a problem on my hands at the moment. (Very sorry if this is a stupid question it is true that I am not the smartest at times). Hopefully someone with a bit more experience might be able to help me out.
At the moment she runs pretty rough. When I unplug the MAP sensor vacuum hose in runs smooth, just rather rich. However, with the MAP sensor all plumbed up it chokes and stalls out. When I give it some gas, it bogs down and backfires as well. Is this a result of a faulty MAP sensor?
I have asked some other Facebook groups and they are suggesting an adjustable fuel pressure regulator. Should I be chasing one of these? Just a bit unsure as I am new to Daihatsu’s and older cars like my Mira, thanks guys for the help. Any recommendations would be greatly appreciated. Also apologies if this in the wrong chat.
