Hi there,
In general, a bad intake manifold in a vehicle has the following symptoms:
1. Rough idling.
2. Engine Misfires.
3. Check the engine light.
3. Reduced fuel efficiency.
4. Reduced power/performance.
5. Coolant leak from a cracked intake manifold can lead to overheating.
There are also specific trouble codes such as P1518, P2007, P2078, and P2014. It is best to run or use a scan tool to isolate and see the part that needs to be replaced. I hope this helps!
