Sounds to me like the Throttle Position Sensor. Thats usually what makes the throttle "rev" But that is not going to make the oil pressure drop. Pull the codes from your car and look them up online. sometimes there is an extra fuse u can add to your panel and turn the key on and it will flash your codes via the check engine light. i.e. if the light flashes 2 times then small pause then 1 time and long pause that is code 21. if there isnt a extra fuse you can usually jump it with a paperclip and pull the codes. not really sure how to do that with yours. but im positive Google knows ;)

Is the check engine light on? Have you had the computer tested for fault codes? If not have it tested, all this is computer controlled.

Rpm at 70 mph. 2000 dodge ram 1500 4x4 with over drive


2000 to 2500. If your not sure the OD is coming on. At 55 MPH, pull the shifter lever down to third gear. If no change, you have no OD. The most common problem with this is that the governor solenoid goes bad. It has the Temp sensor built in. About a $100 fix. Sensor,filter and fluid.

2002 Pontiac Montana trans problem


no I don't think so , it is only the torque converter clutch engaging and disengaging due to engine load. if you want to test this. go on steady speed over 50 mph no gas pedal movement. touch lightly the brake pedal but not braking and release . during this see the rpm drop down and raise

hope it helps

Possibly but to find the fault have the fault codes read . It may be the accelerator position sensor . Don't waste money until you have the codes to point you in the right direction

My 02 trailblazer jumps in rpm's while driving, typically when i am in crusie control over 55 mph.


Sounds like the torque converter is coming out of lockup. A technician with a highend scan tool should take it for a road test to diagnose the condition.

The RPM of Nissan Altima stays high when drive over 65 MPH.


No....the rpms differ from engine to engine and from manufacturer to manufacturer. RPM's are always higher at higher speeds.

Speedometer not working on 2002 dodge ram 1500


Removed cluster from dashboard and unplugged & turned the whole cluster clockwise very slowly and needle started moving from 150 mph back down to 0 mph when rotation was completely done. Kept cluster upright while re-installing and plugged back in the plugs on back and everything was fine. Called local Dodge dealer and told me would take 30-45 minutes to reset and would cost approximately $70 to fix. Took about 8-10 minutes of my time and saved myself $70. This may not work for everyone but this was my amazing quick fix thanks to GOD for giving me this thought to try this.
