Excessive cranking & carb cleaner near exhaust manifold stalls car

[Christopher Gharibo]

My '91 coupe always needs excessive cranking to start unless I use throttle,
hot or cold. My ISV is new and gets power. Idle speed and CO are factory spec.


As I spray carb cleaner to find a stubborn vacuum leak near the exhaust
manifold, my car stalls.

I am assuming this is my exhaust manifold or gasket. Is this tough to
replace?

Any suggestions on excessive cranking? There does not appear to be a vacuum
leak.

Thanks!
