I was going thru with my soapy water and saw some leaking around the screw location. Pretty much all of them was leaking. Anyhow, I tighten them some and it seem the leak stopped. Is this a sign of some bad? Could that small leak cause something esle?

Any advice will be great.

Thanks.

 

As long as they’re all tight now you should be fine! If it’s leaking in boost and the FMU is not seeing all the boost you very well could be starving the motor for fuel!
BUT if you tightened all the fittings up and there seems to be no leak now then you are fine

 

cool thanks... i'm going to throw in a fuel pressure gauge one of these days. :-D

 

i had a warm up idle fluctuation that was strange cause i know i didnt have any air bubbles in the coolant, and no hugh vacuum leaks....

but 2 days ago i swapped out fmu's to check something else completly.

and my warm up idle is fine now.... so they can leak, and they suck.... i hate mine

check sig, i need to get rid of it, standalone(i want aem) is the only way to go

 

yeah.. i know the FMU isn't the best... but since im still battling other problems... like no boost... i'll have to hold off on anything thing else right now...

 

yeah no i understand that, wasnt trying to sell you anything.... i read my post again and it seemed like that.....

how you get them sorted, as i have learned, EVERYTHING can be to blame
