I have an 02 TL with about 95k miles. Just picked it up used about 2 weeks ago from a dealer. The car is perfectly fine, good condition, everything works well until I noticed the RPM tach freezes and jumps when I was freeway cruising.

For example, I would notice the RPM tach would stay at 2k RPM even if I am softly accelerating and suddenly jump up to 2.5k then 3k RPM. After 3k RPM, it rises smoothly.

I asked a few of my car friends and they all replied the same way saying the odometer had been adjusted...

Need your input if that is the case or just a technical issue with the gauge.

Thanks!

 

has anyone had this problem before??

 

if we had old type guages they may be right
but its all electronic now

first thing is get the battery tested- low voltage will trick sensors into false codes!
Have the parts store do that and a free code reading to see if any clues there

could be a loose ground wire or bad wire

any work done on the car before you bought it that the dealer admitted to?

 

take it back to the dealer
