Yesterday I drove home in the rain. Parked my car, went inside then came out to my car to go to the gym. I drove to the end of my street(200 yards), if I went over 2.5k rpms in both 1&2nd gear the car would jolt forwards and the rpms would be inconsistent. I turned around and parked my car with the engine on, it didn’t sound right. When I revved the engine not in gear it felt like it was restricted and it felt like the engine shook side to side.

I turned the car off, went inside and brought my friend out to show him. I was unable to reproduce the behavior. Drive to work this morning was fine....

Car is currently at a Nissan dealership, they said they couldn’t find anything. Also there is a rough sound coming from the front left portion of the engine bay when idling.

 

everytime it rains real hard my car kinda bogs down and loses power..I have brought it in many times and they find nothing.

 

It wasnt raining that hard.... There was just a monsoon for like 6 days last week, but I didnt drive it for two of them.

I am still wondering why it is idling like that, noise is coming from the front left.
