Default My car is stuttering and shaking

Its stutters when i take off from a stop and now its stutters/shakes and rocks when i am at a stop. This went on about 6 months ago and then i changed my spark plugs and went away and it just started up again.

Any ideas of what it can be?

I have a 94 corolla, 150k miles.

Thanks!

Ignition Control Module, Distributor Cap, Change the Plugs, Air filter, Fuel Filter, idle Control Motor, Vacuum Lines. Any one of those or a combination.

The ignition control module, distributor cap, and spark plugs are my first thought, shouldnt be more than $200 if you pay a mechanic to do it, half if you DIY. After that check the air and fuel filter which probably need replacing anyway, and I vaugley remember a weird shaped vac line going around the back of the engine that most mechanics would have replaced with a foot of regular vac line instead of the curves piece from the manufacturer, which causes it to rub instead of curving around a bracket.

^^^Just stick to Army stuff. LOL

IAC Motor has nothing to do with shuttering once the throttle is cracked open. Don't replace the ignition module, its not a component that wears out.

Replace the following with Either NGK or Denso parts:
1. Spark Plugs
2. Spark Plug Wires
3. Distributor Cap and Rotor

If the thing still shakes upon take off, you are going to have to take it somewhere to see if a specific cylinder is misfiring or if its random. It could be a bad fuel injector, bad coil, plugged converter, low compression on a cylinder etc. etc. etc. I would drive it, but you live too far away.

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 have no idea what a vacuum line is or where my air filter is...I guess the manual and I will be spending some quality time together.

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.

No on the plugs, but it could be the wires IF the engine is actually misfiring. When you get on the gas, does the shaking go away? Like its only at idle?

Las Vegas is about 3.5 hours away, unless I take a bike..then about 2. lol

theres a delay and a stutter when i get on the gas from the stop but yes it goes away once i start going.

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.

let me ask something simple, that nobody else has. do you have a check engine light on the dash lit up? if so, have autozone pull the codes and see whats going on. THEN fix the problem rather than grasp at straws.

its possible that you have a bad engine mount, shitty spark plugs, maybe buy gas at a shitty station, have a vacuum leak, or several other potential issues. I'd start simple though and evaluate the condition of the vac lines.
