i just got a 94 LS and it seems like the Fuel and ECT gauges are off wack.... for example, I just recently topped off my tank, and about 40 miles of driving, the dam needle dropped down to 3/4 already... i'm 100% sure the car isn't running rich because I dont see any black smoke coming out the tail pipe, nor does the car run bad/rough...

also, my dam engine temp gauge seems to be dead and works when it wants to... while idling, it will go up to the normal position, but when I"m driving, the needle drops to COLD.. I also noticed that my heater doesn't blow as hot as in my civic no matter if I put it on REFRESH or RECIRCULATE and at max HEAT....

has anybody else have this problem?? Please help me out.. BTW, I also swapped out the LS gauge cluster for a GSR cluster, and the gauges still are acting the same....

 

I am not quite sure about the fuel gauge, but my temp gauge did the same thing when my thermostat went bad. Just change the thermostat and that should fix the temp gauge problem.
