well for one ...it is a 17 year old car...so its not gunna be the smoothest anyway.. but what i was thinking is...do you have aftermarket exhaust? thats what my car did...i put some aspetos between the firewall and piping where it was vibrating and it took care of it

first thing to check would be motor mounts. That is a big contributor to vibration.

could be the heat shield on your catalytic converter. ive heard of that problem many times.

That would not make the car "vibrate like crazy" as mentioned. It would just make noise.

mine did the same thing yesterday, come to find out my bass knob was up too high lol.

If it's an automatic I would check the rear motor mount. The automatic rear motor mount is hydraulically controlled to reduce the vibrations by opening up a secondary chamber, or something like that, so it becomes softer at low rpms. They have a tendancy of going out, mine used to vibrate like crazy too, replaced the rear motor mount, and it's all good now.

^^^ lol.
91CB7650 you're on the right track thinking its your motor mounts. does the vibration only occur when in gear or does it happen in park as well? if it only happens in gear, its the motor mounts (most likely the rear one). and it happens even when out of gear (neutral/park), i dont know what to tell you

i have the same prob to a point but my does it when i just sit there and my rpms jump around its bad to the point where my lights dim

[CB7Man]

RPM too low obviously
Any car will vibrate (Especially a I-4) at 300-500 rpms
Mine does it, albeit very little it seems to like idleing at 350
Whats your hot idle in Park?

wheres a good place to get a new motor mount???(cheap price)

[ancona46]

autozone or ebay

[crazymike]

ok cool. i was looking at mine this morning because my car vibrates alot also. and i need at least a new front motor mount.ahvent looked at the other one/ones yet.

how hard is to change motor mount? and is there a DIY?

hi I'm having the same issues as well so I did a used part search and have had about 20 different used parts places around quoting me around $60-70 for all 3 motor mounts. I really wanted to get some junk mounts that are craped out and do some urethane inserts and try out some 60shore mounts and see if they work better... Figure its worth $20-30 buts for the attempt. Those hydrolic fluid mounts I remember being a problem on my 93EX and cost something like $200 in the late 90s to repair.
