[imye30]

Wen driving around the engine is not running smooth an seams to jerk threw the gear ratios when idle its ok any ideas or do I need to get it. Tuned up after doing a engine swap

mine used to do something similar to that and play up mine was just the blue temp sensor

[imye30]

What ECU are you using? i remember your previous posts.

[imye30]

was using the 320i one but changed to the 325i ecu now to match it up with engine

Check the small round plug under the inlet manifold, they can corrode and cause running problems.

[imye30]

is there a name for the plug i will check diagram on realoem to see were abouts it is

[ross2009]

just look by the side of the block on the inlet side where ya loom runs youll see it its what connects ya injection loom to the main loom

[imye30]

ok will do the manifold was a new one that i put on but did not change any thing on the block

[ross2009]

no you dont have to change the manifold just look underneth it there is a plug just open it and have a look at the pins
