RPM drop while driving
When driving every once in awhile my RPM will just drop. Sometimes it happens during acceleration or just coasting.
It use to drop and the car would turn off. After replacing CPS it happens less often and doesn't die but recovers. I also cleaned the IAC
The only thing left I can imagine of replacing is fuel pump or TPS.
Occasionally it takes a few seconds for the the car to crank and start. If that has anything to do with it.
And obviously it happens so intermittently that I can't check fuel rail for pressure.
What do you guys think?

I meant to say I did not clean throttle body. I guess I will be doing that tommorow as well

Also, my gas gauge tends to move alot before it settles at the actually measurement. And it always takes forever to start after pumping gas
