HELP!!! HUD PROBLEMS AND OTHER

[illuzionz7o2]

Well...first off im new to this forum. im having problems not only with my HUD, but with everything on the left side of my rpm gauge. everything from the rpm gauge and to the right works, but nothing to the left of it works. could it be some kind of electrical problem or is there a unit i need to replace? also...im having some kind of throttle problem...atleast thats what i think it is. when my car hits certain rpms, the throttle cuts off. i can get to 5k rpms in first, 4500 rpms in second, and the point of cut off decreases as i go to higher gears, 5th only goes to about 3500. just wondering if anyone can help me out with any of this. thanks.

btw: the car is a 1990 240sx SE coupe

the gauge problem could be related to a bulb being burnt out... that certainly what it sounds like to me....

You can verify this and see if you can see anything by looking really close at the HUD unit. You should see the pixels but it just wont be lit up.

Did one of the plugs on the back of the cluster pop off? Higher gears, lower power? Got any other details on this?

the rpm problem could stem from a bad vehicle speed sensor. it sits on the trans and is the speed limiter for 5th gear.
