I just recently installed a JWT Pop-Charger/Z-Tube combo in my G and a friend of mine wanted to see it.. So of course, very please with my new little addition, I eagerly pop the hood and give the engine a few nice revs to hear that sweet little "pop" the charger makes..

Now, I guess I just haven't paid much attention to my engine while it's actually running, or this is a new issue.. But I noticed my engine shakes a considerable amount while revving it in park. Is this normal turning/side motion? Or could this be something serious? Engine mount?

I have no lights on (so no missfire or anything) and the car doesn't idle/accelerate/reverse rough.. So I'm not sure what it could be. How would I go about checking my mounts?

I'll try to upload a video once I get my car back (it's in the shop.. Got rear-ended.. New bumper for my baby ) to try to give a better example.. But I'm just looking for some input. How much is normal engine shaking/vibration? Could it be anything serious?

I've also been looking at a Stillen Engine Damper Brace.. Wondering, is it worth the money? General inexpensive ($160 I think.) Or are there others anyone would recommend cheaper/same of equal/better quality? I feel like, in my case, the extra forward motion would definitely give my acceleration a better feel if my engine is really shaking this much.

Also, I'm looking at Sways and a strut bar soon, so would a damper affect that in any sense?

Sorry for so many questions, but I appreciate any input! Thanks guys.

 

Thats what mine did when I first installed the jwt but after resetting battery, everything was fine.

 

having a very similar problem my entire engine is stock as of now and when ever i come to a stop and idle for a few seconds i feel a shaking like its about to cut off but never does. does the same thing in park.

 

That's the thing.. Mine doesn't do it while I'm driving.. Or if it does, I don't feel it.. That's what I'm wondering.. Is it normal? Cause I don't feel ANYTHING while driving.. No shaking or anything.. I can just SEE it shaking and I want to make sure it's just normal engine vibrations.

 

i dont feel it when im accelerating at all only when i come to a complete stop or its in park. asked around and no one seems to be sure. one person told me it could be a sensor (maf or idle) and the shaking im feeling cant be normal

 

Yeah, yours sounds like it could be the MAF or even a missfire. Any engine lights? I would get it checked out. But that's not the same problem I'm having.

 

yea i was hopin it was just a spark plug or somethin easier to fix since the maf is about 200+ but its goin in for a full service in a week or 2 so ill know exactly pretty soon good luck with urs

 

If you feel your car shake when at a red light or parked check your oil level. Mine did that when the oil was low, don't ask me why or how

Also spark plugs, maf and TB might need replacing or just cleaning.

There is a DIY for TB cleaning, very effective... did it to mine which was dirty as hell and there was a significant improvement to my idle... just be sure to do the resets and also make sure if you do them correctly (one of them takes a few tries to do)

 

Most likely idle re-learn, but possible spark plugs/air leak.

Also If you touch the butterfly portion of that TB the wrong way, it gets out of calibration, possibly needing a new one.

 

Check your motor mounts
