As said above, not having a speedometer gear can indeed cause problems since the engine computer uses the output signal from the speedometer gear sensor for all kinds of important decisions/adjustments it makes. I have no idea why you had trouble getting the speedometer gear housing reinstalled, the AA SYE kit is widely used and has no issues with reusing the factory speedometer gear housing. And the engine rpms are totally controlled by the computer so if the computer isn't getting all the data like from the speedometer gear, the engine will start having strange issues.
When you have a choice, buy American made.
