Dazrsturbo Posted September 21, 2018 Share Posted September 21, 2018 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! Quote Link to comment Share on other sites More sharing options...

Dazrsturbo Posted September 23, 2018 Author Share Posted September 23, 2018 Checked for leaks but couldn’t find aything. When the engine gets warm it starts to drop rpm and stalls Quote Link to comment Share on other sites More sharing options...
Paul Grainger Posted September 23, 2018 Share Posted September 23, 2018 Have you any exhaust gas data? The metering valves are known for sticking. Cheers Quote Link to comment Share on other sites More sharing options...

Paul Grainger Posted September 27, 2018 Share Posted September 27, 2018 Exhaust gas data would be the way. Adjust it and see if the readings change. You could take it apart and wd40 everything. Cheers Quote Link to comment Share on other sites More sharing options...
