Having problems with your 2004 Mazda 3 ?
Mazda3 rpm's go up and down while driving
\015 Few days ago I had the car serviced then on the way home i stopped filled up and went and bought Gumout complete fuel system cleaner. \012The next day while driving my rpm guage started jumping from 2000 - 5000 rpm's depending on the speed was the jump around 45mph it would jump 2000 - 4000 rpm's. Its been over a week now the problem still hasnt worked itself out and i filled up twice since. I did notice the rpm's jump less while in cruise control so i use that alot now.\015
After I had the throttle body of my 2005 mazda3 cleaned, the RPMs would jump drastically - bouncing back and forth up to 16 times! The service manager seemed perplexed...and ultimately the solution was TIME. The bouncing gradually diminished and then stopped...can't remember for sure, but it was probably over about 6 weeks, maybe about 1000 miles.
