Having a rpm issue when accelerating

[Robert Harris]

Made a short video of the issue I am having, but its taking forever to upload. Will edit this when I get off of work and include it in this message.

It happens at :30, :46, 1:12, and 1:25

2001 dodge stratus rt coupe 3.0 sohc v6 manual transmission

What happens is when I am just cruising, lets say 55 mph in 5th gear, when I go to accelerate whether I downshift or not the rpm’s will rise a little fast (about 500) then drop back to where they were and continue to rise as normal.

I have read some posts online saying it could be anything from a vacuum leak to my clutch. I don’t think it’s the clutch since while the rpm’s are rising faster than they should be I am gaining speed. If the clutch was slipping I wouldn’t think I would still gain speed, but it might still be transferring some power? I don’t know much about vehicles. Any advice would be amazing. I have driving this car 2k miles in about 2 weeks so I need to make sure it is in great shape before then.

Another comment to add that might be related is very rarely I will be driving and all of a sudden it’s like I hit a wall. Car has a huge jerk and lose of power but recovers within a blink of a eye like nothing happened.

ps: If anyone can tell me what that darn clanking noise is that would be awesome. Have my front struts replaced and it made a little difference but has recently gotten louder. Maybe a broken motor mount?

Included a video in the first post. I included the times to watch at so you know what to look for. Any help will be greatly appreciated.

I believe the check engine light is on. can you
have it read and post the code.

The huge clunk most def sounds like da motor mount. That’s an easy fix. As far as the other problem u may need a new vaccuum line. Same thing happen to my mustang

I can’t get it checked atm, studying for a final. Will do tomorrow though and let you know what comes up. I really do hope it is just a vaccuum line.

Alright, I had my check engine light read and it came up as a generic egr code. Guy said he could look at it for me and try to find out what is causing the problem for 75 bucks which I don’t have atm.

[college man]

What was the code?

Helps to know the code. But any parts store should be able to read the code for free to tell you a general idea of what’s going on. Usually if it’s a vacuum line; you would loose RPM, but in the video your gaining it.
