Well...I don't know if you guys read my previous threads but my car didnt start for a while.

It was so stupid I don't even want to say why. I guess all the problems are so fustrating until you find out that it was something so small and it turns out to be silly instead of fustrating.

Anyways, before my car "didn't start" it was hessitating. If I were to step on the gas, there would be a delay for a bit and then it would be normal. I guess you can say it kinda lags at low RPM's. I'm not too sure what can be wrong. The spark plugs are fine and all coils are perfect. Anyone have any suggestions?

-ThankS.

 

I think your talking about the delay that happens between going from low throttle to full throttle caused by the fmu. What happens is when you are driving at a constant speed or just sitting there at the line your car is sitting in negative vacum in which the fmu is not building any fuel pressure, so lets say your sitting in 2nd gear at 30mph at a constant throttle and you floor your car it bogs down for a second which is caused by running out of fuel pressure because your still in negative vacum and the fmu is not working but once you get posstive vacum or boost pressure your fmu starts working and everything is great and the power is all there..
Thats also why they are called boost dependant Fmu's.

I hope that I was of some help.

you might wanna check to see if the fmu disk is sticking or not...
