After my head rebuild I’ve developed a slight on and off rough idle (will the madness with this car never end !)
As always my first step was to do a compression check. Since the fuel pump relay on my car is behind the right (passengers) knee trim and difficult to get to I simply unplugged the electrical connectors to the fuel injectors to shut the fuel off while I did the test … and … great news
#1 152 psi
#2 150
#3 154
#4 153
#5 150
#6 150
Since my 3.6L is a “normal” (low compression) engine these are numbers I dream about. Since it’s the first compression check I’ve done since the top of the engine was rebuilt I was holding my breath because you just never know… did I screw something up during the rebuild? … ME … uh no way
Next step will be to check for any loose hoses or vacuum leaks
