DanChave 98 Posted November 20, 2014 Report Share Posted November 20, 2014 I have just fitted the 2.9 ABV into my mk3 over the last two days, when I took the engine out, I left the engine loom connected and just disconnected the main multiplug. Now, it will run, but only with my foot on the throttle, once I take my foot off, the revs drop and cut out. So I got to looking at what could be wrong and noticed there is a temp sensor in the inlet manifold but no plug for it! I looked at a customers OBD2 Highline, and his has the loom plug but mine hasn't! I also looked at the engine loom from the old OBD1 AAA and that also has the sensor but no plug, Why is this??

Therusterman 59 Posted November 20, 2014 Report Share Posted November 20, 2014 Seems odd, iirc the connector for it should be with the injector wiring Link to post Share on other sites
DanChave 98 Posted November 21, 2014 Author Report Share Posted November 21, 2014 Found it! For some reason the owner before me had it plugged into the third sensor on the thermostat housing lol! turns out the third sensor (BLACK) is for aircon only so not needed Link to post Share on other sites
