Caprice rough idle error code

Hey guys, got a bit of a head-scratcher with my 2005 Chevy Caprice, gas engine. I'm getting an error code and the idle's rough. I'm suspecting a defective engine mount, maybe a bad connection somewhere?

Summary of the thread

A 2005 Chevy Caprice is experiencing rough idling and an error code, leading to the suspicion of a defective engine mount or a bad connection. The issue is likely related to a defective cable or plug connection rather than the engine mount itself. The recommended solution is to have a mechanic inspect and fix the connections, which resolved the problem and restored smooth operation.

Rough idling and error codes with a Caprice? Sounds familiar! I had similar vibration issues with my Caprice. Engine mounts are definitely a prime suspect. Sometimes, it's not just the mount itself, but the wiring or the plug connected to it. A defective cable can cause all sorts of weird readings and uneven engine performance. Especially check the connections to the engine mounts; sometimes, the vibrations can loosen them over time. It could also be simple mount wear.

Interesting, thanks! By any chance do you remember any specific part or error code, so I can look more closely?

I didn't dig in myself at that time, because my skills in that space are a bit rusty. I brought it to a workshop I trust, so they could have a look. They told me, that it's likely a defective cable or plug connection, because the engine mount itself was still intact. Best is to take it to a local mechanic to get it fixed, before it can do more damage.

Thanks so much for the insight! Took it to the shop, and you nailed it. It was indeed a defective connector on the engine mount. 95€ and it runs like new again!
