Lol.
I've never heard the word "gritty" used to describe acceleration before...
You may have started something new here, FA.
"How's your car been running lately, FA"?
"It's been running really gritty".

Haha. I kind of like it!

I MAY just start using it...

Since gritty rhymes with *****ty, we'll assume that something's wrong with your car.
Can you pin down the grittyness a little better for us? Does it seem to be a gritty hesitation with the engine? Gritty vibration? Or does it just sound gritty when you're hard on the accelerator?

I know, it's sometimes difficult to describe things with words.
It sounds like it's some kind of vibration. Does it seem to be coming from the engine or the transmission?
Can you only feel it through the gas pedal or does it travel through the whole car?
Does the engine seem to be running the same as before this occurred?
Does the transmission seem to be working the same as when everything felt "smooth"?

Could be some bad gas... Happened to me once. Could be bad coil or plugs. Vaccine leak. Those are the easy fixes. Harder could be a timing chain issue like timing guide or could be broken trans or motor mount. Does it idle fine. How about vibration when you rev motor in park. I had a motor mount go bad and the engine would make whole car shake at rev and idle in park.

Is it some type of hesitation? A noise? Dirty throttle cable? You drunk or drugs? A vibration?

Does it do it when in park or neutral? Only in gear?

Does it do it when the car shifts gears (into a lower RPM) than you press the gas and it hesitates and makes that noise and picks back up?

Gritty sound like the sand in an etch a sketch? Could be low octane gas that would cause pinging under heavy load at higher rpm. Fill tank with 93 for a few tanks and a bottle of fuel system cleaner.

These engines like 93 that's all I use.

Buy a cheap coil from jegs for 17 bucks. Use it to change one coil at a time and see if you find a flaky coil. I have one in my trunk as a emergency spare.

It could be and yes, you can test it. If you search cliffyk's posts, the procedure is there.
Have you noticed any loss of power since this started happening?
It DOES kind of sound like a broken motor OR transmission mount.
In any case, find a friend to sit in the car and hold the brake and step on the accelerator to load everything up like you are accelerating very hard, while you watch the engine to see if it rolls excessively to the side. Its a good idea to block the front wheels during this procedure. Also, look and listen for anything else that seems abnormal.
Anything GRITTY!

Rockauto sells just the boot and spring kit for about $2 instead of $40+ each for the coils.
I understand that the coils themselves rarely go bad, its the insulator and spring that fail, mostly.

Two spark plugs?!??
Yes, change out the boots that aren't new and not sure what you have going on with the spark plugs but make sure they are reasonably fresh and have the correct gap...

Unless you've done them recently, it never hurts to have a look. Just replace all of the boots while you have them out... they're cheap.

yeah replaced the boots/springs and plugs just before winter... so should be fine but have no idea why my car feels like this... might just bite the bullet and bring it into a shop and have the mechanic take it for a quick ride. I can do the work myself most likely but need to know what work to do lol
