Red "Vicks" - '93 Civic VX
90 day: 52.23 mpg (US)
VX owner needs help. RPM is incorrect.

After driving back from Buffalo last night, I noticed during hill climbing, my car takes a while to get out of lean burn. It usually gets out at 1-3 seconds but while the pedal is still depressed it won't accelerate at all. I had to release the pedal and applied it again. This was doing 65MPH going uphill accelerating on 5th.

Earlier while driving my car, I also noticed the RPM drop to 0 every times I press the clutch in. And when accelerating, the rpm seems laggy. SIL goes on at 1000-1600rpm 1-4 gears. Don't know if this was the reason affecting my mileage last night but I'm hoping to get it fix. Also during idle, the needle will be resting at 0.

Any answer to this problem?

Perhaps...the big black cube thing...I believe that's usually the cause.

rotor?

if its an ignition problem you should probably replace the cap, rotor, plugs, wires if they haven't been replaced in awhile.

I notice i can gradually increase throttle until vacuum is @ 5-7 inches while in leanburn. Its quite a bit of throttle without accelerating. Also as NTK sensors get old they start reacting slower. Sorry, not much help

Plugs are good. I had a mechanic moves the speedo wires to make it idle at 700-800. But when driving and coasting in neutral, it fluctuates up and down between 0/800. This happens when braking also. I'm thinking that the cluster is broken, and its rare to find a "VX" cluster with similar mileage. Last resort will be to take it to the dealer and have them check up on the entire issue (which I really really don't want to do).
