Going down the highway at 55-60 mph I just barely tap the gas and the vehicle jumps, I press the gas hard and it stops, leave off the gas check engine light blinks and jumping continues.


A blinking light usually means exhaust system probably catalic converter. You most likely have a small blockage in it which means exhaust can't get out correctly. Have vehicle scanned at autozone or similar.

Hi! My rpm gauge on my 1995 3000gt vr4 will stay at zero until reved at high rpms it will start jumping wildly. What might this be?


Most likely your tooth on your needle has worn out. Happened to me on the mph cluster. Its easier to change out the whole speedo. Hope this Helps!

Down shifting at high rpm's


Sorry there is no adjustment screw to this. Everthing is controled by the ECU now. There are after market piggy back system you can buy to keep the transmission locked up longer but that's expensive. There are many good speed shops out there that can reprogram you ECU to how you'ld like it to perform for what you use it for. Even some transmission shop can do that for you with a Pro link. Good luck

1992 Chevy Suburban rpms jump at 60+ mph


When the transmission jumps the extra RPM by 200 or 300 RPM. That's your Torque Converter Clutch lock up disengaging or it's slipping. Pull the transmission dip stick out and check the fluid level and condition of the fluid, look to see that it's not burning. If the fluid is not burning then it's the Torque converter clutch unlocking and the Throttle position Sensor may need to be readjusted, or if the transmission is still running off a TV cable. The TV cable may need to be adjusted and or the transmission filter may be dirty and needs to be changed. Take it to a transmission shop and explain to them what the transmission is doing. I'm not sure if your transmission is an 4L80 or a 4L80E. If it's the 4L80E the PCM and ECM control the lock up to your converter. If the PCM detects a problem with the transmission, it drops the transmission fluid pressure to the converter clutch. If it's a 4L80, it's controlled by the TV cable and vacuum lines to the transmission modulator. Regardless they can look in to this when they change the transmission fluid and filter. Recap: Have the Suburban's ECM scanned for any transmission DTC codes. Service the transmission if the fluid is dark in colour and burnt. Adjust any linkage to the transmission that is an issue to it's performance. Good luck and keep me posted, be glad to help.

RPM jumps


Does the RPM seem to bog down around 3000 - 3500? If so you have fuel delivery problem> Start with the filter.
