why does my shake when its in idle? is it my motor running rough, if so what do i need to fix. if not what the hell is going on??

 

All the time or when ac kicks on? Check engine light? If no, check motor mounts

 

Is the front mount torn/broken if so the rear mount is also most likely worn and needs to be replaced.
When was the last time it had a tune up?
Pull your spark plugs, check for wear and regap, see if that improves the idle, if so time for new plugs.
Check your rotor/cap. On the cap look at the underside of the terminals. Are they worn or do they have yellow boogers on them, is for clean them up and see if that improves idle, if so, time to replace.
Check resistance of the spark plug wires, preferably when they are still hot.

 

yes check engine light is on. i just bought the car about a week ago, thought it was my o2 because it was pretty much rusted out. replaced that and light is still on. noticed the shakiness about two days ago. ive never done work to a car so all this is new to me. i dont lnow how long its been sonce the last tune up. but ima be asking a lot of questions because i want this thing looking and riding nice.

 

Best would be to use an OBDII code reader to check the codes. OBDII port is located behind the ash tray, open door down, gently press metal locking tab down and pull ashtray out. You will see the 16pin OBDII connector.

Next would be to retrieve codes via the OBDI method.
Look under the center of the glove box.
Note the two wire blue connector.
Pull it down.
Jumper it with a wire or paper clip.
Turn Ignition Switch to II(ON).
Record codes from CEL/D4/ABS/etc warning lamps.
Post them here.

 

i took it to a shop two days ago, so when i find out whats actully wrong with it, ill post back on here

 

FYI - a wireless OBDII reader is only about $15 and you can connect with your smartphone. I just diagnosed a P0401 trouble code (which threw a check engine light). Cleaned out the EGR ports and cleared the code with the reader. We'll see in the next day or so if the check engine light comes back but I must say it's running much better; no more shaking at idle, no more knocking and more power. Gotta love Google/YouTube!
