Car problems.... shaking when I start it?
I have a 2004 Chevy Optra with 102000 km on it. The check engine light came on about a month ago, so I took it in and apparently it was just my gas cap that didn't seal the right way. Then about two weeks later it started shaking when I started it (kind of a vibration that lasts for about two minutes) and the check engine light came on flashing, then turned off the next day, then solid the next and then off again.
So I got that checked out and they injected the engine to clean out any deposits and also put in new spark plugs. That was about 3 weeks ago.
Now for the past two days, it has started shaking again. I have checked the gas cap to make sure that it's tight. Today the check engine light came on again.
So I am wondering what is up, and if there is something that would cause this that I can fix myself or do for a relatively moderate price.
It seems to be worse in hot weather, but is also bad in the morning when it is colder. Thank you in advance for helpful answers.
It's not the oil. I just changed it. The rumbling seems to be coming from the engine itself, but I haven't been able to see the source. When they checked it shouldn't they have checked the fuel filter? Thanks for the answers so far!

Alot of possibilities. If you have any type of power loss Id get your ignition looked into, could be your missing on a cylinder due to a bad wire or DIS, something like that. If its just a shaking maybe its a bad motor mount. Could even be a bad ground somewhere, just so much it could be. Wheres the rattle coming from? Or is it just the entire engine shaking?

check your oil it sometimes lack of oil in motor try a fuel cleaner sometimes it dirty fuel could also be going through the system check your hole motor top bottom could be a fan belt if your cars on gas then it will shake cause gas dont start the engine very well wen its cold usually u gotta switch it to fuel to start it then when its worm enough switch it back to gas pretty much i had the same problem with my car
