I just got my IROC back from the shippers & she runs rough.
It will idle no problem but when you put her into gear & give her some gas
she hesitates even when running steady you can feel the lagging.
I'm going to check the timing ?
Could it be any of the vacuum lines as well it's a 305// 4 barrel. I put
an K&N Air filter package on a few months ago ?
Thx in advance.
