Mk4 xr3i mfi bad running
Got a problem with my 89 xr3i cab. 1.6 mfi . I think it’s running rich and it seems to not be getting enough air. If I pull the vacuum pipe off where the cold start valve is on the inlet manifold it runs a lot better due to sucking in more air. Anyone know what could be causing this please and how to resolve. Thanks!

Have you had in on a gas analyser to actually check the mixture?
Could also be the WUR (warm up regulator) but without a fuel pressure gauge its pretty difficult to even do basic troubleshooting on the K-Jet system. Easy enough to make your own tho
