The 180 is still in spec I believe but it is very very low, normal should be about 200 and above.. mine is like 220 218 221 220

Absolutely your #3 needs an aquarium air line and oxygen tank!!!

Seriously, you need to pay attention to #3. That compression is hanging in the balance. The only reason your car is running is because of the 3 good cylinders.
