Q: Fluctuation in RPM's on 2004 Suzuki Verona

This has been an issue that is getting worse. At first the rpm's were dropping where the car would sometimes cut-off. Now the rpm's will raise and lower quite often. The car's engine seems to "rev" all by itself. Especially when the car is shifted from drive to reverse or vice versa or when I am stopping (ie:traffic lights, ect). It's strange, when I go to brake, the rpm's will raise and the engine will "rev" and the car will kind-of "jump forward" like it's being pushed by this invisible "force" before actually coming to a complete stop. The same thing has started to happen when I am driving...Even when I take my foot off of the accelerator my car sometimes feels like it's being magically pushed by some unknown force...then the engine will rev and the rpm will go from like 1 to like 2 or 3 in a split second. I called a friend of mine who is a mechanic for a Volvo dealership and he says it sounds like my torque module is going. Too bad he doesn't specialize in Suzuki's. Any insight to this issue?

Throttle body issues are common. Wiring around the trans and behind the intake are also common. No easy diagnosis.
Yeah no bs...8 months after I bought the car I had to replace the whole wire harness for the engine. Needless to say Suzukis "so-called" upstanding warranty didn't cover this issue....

I'm just at my wits end with this car. There just seems to be one problem after another. I finish paying my car payment next month and am planning on getting rid of this car as fast as possible...
have the same problem now after cleaning the throttle body anyone have an answer ??
Yeah I was recommended NOT to clean my throttle-body because sometime it can make the problem worse??? Whether that is fact or fiction, I do not know...
