Default help!!! RPMs bounce up and down between 2-3k, heavy engine vibration

Hello,

Civic LX 75k miles

I am experiencing heavy vibration in engine and RPMs are struggling to move when I accelerate specifically in,

2nd gear between 2k-4k
3rd gear between 2k-3k
4th gear between 3-4k
5th gear between 2-3k

However, this issue is not as seriouse when you accelerate very slowly, mainly when I accelerate a little hard. (I am not flooring my car) The car runs and I drove it today 25 miles to and back from work but it does appear to be an issue not to be ignored.

Also, last week my check engine light came on, and in first gear my car would struggle to accelerate, heavy vibration in engine, RPMS struggled to rise when I accelerated. The mechanic replaced the direct ignition coil, spark plugs, battery. Car runs and I drove it 70 miles home ok but then after 1 day I noticed the above issue..

I am about to drive 190 miles tomorrow for work. Please get back to me... Not sure if I should make this drive.

Please help and thank you to who does.

Step 1: call the mechanic you had 'fix' your car and ask what's up.

Step 2: tell us what year Civic you have.
