101, if I replaced the plugs and the wires 6 months ago, can it be bad already?
you don't think its the air filter? I just got my oil changed on Tuesday and they supposedly looked at the air filter and shook it out, and today especially when i came to a stop, it was just shaking all over the place! Ugghh i hate not knowing anything about cars. I have the manual but its kind of hard to troubleshoot when i have no idea what to look for. |

I want to say cracked vacuum line or bad spark plug wire. I know you said that you are not mechanically adept but with the car running try spaying some carb cleaner around the vac lines and see if this affects the motor idle. It seems that there is a vac module that controls idle/fast idle on these cars. The fact that it's getting progressively worse suggests something along these lines. Also because the engine was just fiddled with during your oil change may have exacerbated the condition. If you're lucky, you just have a crack on the end of a line which can be cut off and re-attached. I wouldn't run out and buy a bunch of parts just yet. Also, the fuel filter or even the fuel pump are suspect in my mind. For your own piece of mind, try taking out the air filter and see if it affects the condition. You have nothing to lose but a few minutes of your time.

I could ask the creepy asian guy that lives 5 feet away from me, he owns a shop around the corner and gave me his card. But he's creepy...and he may want to put a big spoiler on the back of my car and a bobblehead on my dashboard. |

On this picture, the guy has painted his "air box" red. It is on the right and is the piece with the large hose/tube coming out of it. The cover is usually held on with a few screws or clips. The clips can be popped with a screwdriver or even a butter knife. If you follow that "hose" to the left, you'll see that it connects to a "valve" which is the throttle body. The throttle body has a couple cables coming off of it and some small hoses which are vacuum lines. From there it goes to the fuel injection system which is that "box" to the left. Also, if you look at the top of the engine, you'll see four wires coming out of it, which are the spark plug wires. I want you to visually inspect them for any cracks and see if they are possibly loose where they plug in to the engine or at the ignition module (the black box between the air box and engine), it's unlikely that your car has a distributor cap. Just make sure that they aren't loose or obviously cracked. If you are feeling really brave, the throttle body has an idle adjustment screw that can be turned to speed up your idle and possibly end you problems. If you look at the throttle body closely, you will see that the cables are attached to a "wheel". The screw controls where the "wheel" stops when the cable is released which controls how fast the motor runs when you aren't pushing the pedal (idle). Now all you have to do is turn that screw 1/4 turn clockwise increments and see if you situation improves. I would do this with the car running but if you are uncomfortable with that, just turn the screw a 1/4, start the car. If it's better good, if not try again. I would not go over one or two full turns. If this doesn't help, I'd try your Asian friend. The steps I have outlined to you are basic and will not harm your car in any way. If adjusting the screw doesn't help, keep track of how much you turned it and just put it back. Last edited by Amber Lamps; 09-26-2009 at 04:30 AM.. |

My guess would be the engine mounts. At that age, the rubber in them is probably disintegrating. A lot of front engine cars will have a mount that goes over or under the radiator to prevent fore/aft rocking. Since that's the way the engine rotates, it can make a lot of noise.

The shaking / rocking starts again when i come to a stop and it got really bad at idle yesterday. It is intermittent though. yesterday it got pretty bad, today there isn't any rocking but there is still a sputter/delay when i first get on the gas. Actually yesterday after all the rocking and such at one point (and it was a bit cooler during the day, don't know if that makes a diiference) when i started it up to go home, i got on the gas and at about 30 mph and there was a surge and all of a sudden it was smooth again for the next 3 miles until i got home. Checked the air filter, it looks pretty good. none of the wires seem to be loose. I put decent gas in it, either at the Chevron, Shell or Circle K. Oil and tranny fluids seem good. |
