I’ve had an issue with weird acceleration. I’m praying it’s not the transmission because I cleaned the throttle body and it worked better for a day or two then the check engine light came on and I needed a tow. The driver luckily used to work at Nissan so he did the idle relearn for me and it worked better again. But I got off the highway and then my car stop accelerating. I pulled to the side turned off and back in again and it was driving again.

I’m thinking if it was my transmission then the rpms would shoot up(right or wrong?). Also If it was my transmission would it be intermittent like that or constant? I wanna make because that costs a lot of money
