I have a 87 CRX with fuel injection. The engine idles fairly rough. I have set the idle to 1000 rpms because of the vibration at lower levels.
The car shows 256k miles and I was told by previous owner that the engine was rebuilt at one time.
A leak down compression test showed only 135 to 145 compression for the cylinders.
I just replaced the fuel injectors because a couple were leaking and I still have the problem.
The spark plug wires, plugs, air filter, rotor and cap have been replaced.
The tach also jumps at times ....I don't know if there is a correlation.....
The car accelerates fine.
Any idea what might be causing this?

It sound like you have a bad starter solenoid.
It clicks like crazy and will not engage the starter if it is bad or going out!
PLEASE RATE THIS SOLUTION! Thank You Very Much!

No dipstick...you verify by havin car first on level ground then.Then when on stable ground remove the 17mm filler plug on upper passenger side of transmission.if fliud flows out of filler plug than level is fine.if does not flow out whenplug removed.RECOMMEND STRONGLY using a honda brand manual transmission fluid in this transmission..it does wonders for shifting or gearing issues.

Perform a valve clearance inspection and adjust if necessary. Tight or sticking valves will cause a misfire or rough running concern. Note: Perform valve adjustment when the engine is stone cold. 4cyl: INT 0.26mm EXH: 0.30mm (V6 engine are hydraulic and no adjust necessary.) Also check for a sticking or stuck open EGR valve. For diagnostic purposes only: Remove the EGR valve. Place a business card over the EGR passage and bolt the EGR valve back on. This plugs the EGR ports and if the misfire goes away the EGR valve is partially stuck open and is defective.
Check for low fuel pressure. Check for low compression. Check cam timing. Check for a weak ignition coil. Also don't over look the possibility of worn or broken engine mounts which cause excessive engine movement and engine vibration. -hope this helps

It's called hunting. You need to clean out the EAVC unit in the intake manifold. Take off the air filter and housing, run carb cleaner through the intake for 20 minutes or so.
Next bleed the radiator by taking the rad cap off and start the car, let the fan kick in twice (about 20 mins again) and the air bubbles will have been forced out.
Take the car for a spin and the vote for me when it's fixed :)
