Shello007 Posted September 27, 2014 Share Posted September 27, 2014 I know this topic has been covered. However, most of the previous complaints were attributed to axles and the likes. I know mine certainly can't be, but then again, you never know. My question is, can a bad batch of petrol be the cause of this vibration? It happens primarily at idle. Normal driving is fairly smooth. I feel it on the steering wheel and also the clutch pedal, half way during engagement. I had the mechanics inspect the car, but they're unable to see any loose or damaged mounts or hoses or anything. Got me going crazy. Link to comment Share on other sites More sharing options...
MrTris Posted September 27, 2014 Share Posted September 27, 2014 Throwing any codes? Could be any number of things, from bad/failing OCVs to broken/hella worn engine mounts. . Can you give us any more info? Link to comment Share on other sites More sharing options...
Shello007 Posted September 27, 2014 Author Share Posted September 27, 2014 No codes. Accessport not showing anything out of the ordinary. At idle, engine is visibly shaking. Not too excessively. During driving, I feel it at slow speeds and through the clutch pedal during shifts. Sent from my SCH-I535 using Tapatalk Link to comment Share on other sites More sharing options...
MrTris Posted September 27, 2014 Share Posted September 27, 2014 Run logs. What's Cylinder Roughness look like at idle? At normal cruising speeds? Link to comment Share on other sites More sharing options...

Well, then, here's your diagnosis: Your car's gonna blow up. Just buy a new shortblock now. /thread Link to comment Share on other sites More sharing options...

turbie Posted September 27, 2014 Share Posted September 27, 2014 Bad idle can cause by dirty thorttle body?? Or maybe the engine mounting is time to be replaced? Link to comment Share on other sites More sharing options...
