My car is the IS 3800 series and it has an rpm issue. when I drive the gauge goes from 2000 to 5000 rpm. This causes a kick in the car. it clears up after it warms up but still jumps. also, when car is cold I have a single misfire when warming it up. i have done everything for preventive maintenance, spark plugs, etc. Do you have a solution for this problem? Thanks, Shane

It sounds like the transmission is slipping i would check the fluid level. If it seems like I am way off base can you please take a quick video and upload it here to the site?

Please let us know what happens.

You can upload a video here at the site using your phone. It is difficult to tell what's going on unless I can see it and hear it.

Lets try running the codes to see what come up
