I have a 95 civic the RPM gauge jumps not a steady rise and sometimes the speedo does not work i dont get any check engine lights

The speed sensor might be bad. I used to own a 99 Mitsubishi Eclipse with the same symptons. The car will start, but will not pass the 1st or 2nd gear, the speedometer will be at 0. I replaced the speed sensor and all the problems went away.

it can only be 2 things.
1: transmission slip
2: engine died, or has weak power.

if you know what engine rpm is, you can solve this riddle.
A: RPM RISES FAST, MPH (SPEED) DONT. BAD TRANNY
B: Rpm sicks low, car dont move, bad engine (weak, or 100 other reasons. but (bad engine power)

it be impossible for me to express RPM with sounds,
so only an RPM gauge works. does your car have one.? "dash"?
im too lazy to look but, most cars have sub models that dont have this
important gauge.

possible crankshaft position sensor

the timing could be off you may have to have it checked and fixed hope this helps

Sounds like wiring problems with the engine harness.
The oil pressure not working could cause the hard starting problem.
The idle problem could be a faulty idle air control valve or a vac leak.
I would start with the check engine light and find out what the codes are.

It's a common problem with the civic's, the speedo is bad, you can try findind one in the bone yard but it may be bad to, the dealer is expensive, In my 95 civic I turn on my tom tom and it has the speed on it, all the other gauges work fine, the odometer will work fine, just the speedo.

All codes are misfires, have you changed plugs and wires ???

You need to check your fuses. The gauges and the lights have a separate fuse

Idle speed control valve located on your throttle body. It has the engine searching for idle, internal plunger is not backing down. This will cause the check engine light to light . if you wont, i think they still offer free check engine light checks at auto zone, i now they still do around here

Hi! The MAF (mass air flow) sensor is surely faulty. The MAF has big contribution on the engine performance specially on the idling an vacuum supply. If the MAF is faulty the rpm will drop eratically or die. Regarding the overheating problem, you may want to check the radiator blower for it may be tripping that sometimes it works and sometimes won't. This can be a good cause. Hope this helps and thank you for using FixYa!
