lower intake manifold might be leaking...

Hey thanks guys... I had it done probably a month ago. I think everything went well... i 'm still evaluating... I wound up paying $450.00 for labor...


The only thing I'm wondering is I thought I saw some oil under the car but its not consistent. I also noticed a coolant or oil smell when driving on the xpressway.. not sure if spillage is still burning off the engine.. I hve been noticing the engine hesitating around 2000rpm. Kind of goes up and downslightly. But I rev up the engine and its gone.. its prob nothing..

Anything after a week, is still a leak. Maybe valve cover gaskets. They are common.

The hesitation, tune up, clean tb etc?

Had valve cover gaskets replacedx with the lim job..
Tuneup done 8 months ago... maybe the throttle body..
