    I checked the vaccume, its ok, after i replaced the distributer the car ran fine for 30 miles, then it started to spit and sputter, only with a load, at idle to red line no load it's fine, all vaccumme lines look good no cracks or rubb throughs, all lines are rubber, and sealed tight on ports, could it be fuel pressure regulator?, or injectors?

  • happyhapka Jun 30, 2008

    Just shits and giggles. I disconnected the fuel pressure regulator, and plugged the vaccumme line and test drove it and it ran like a rapped ape, so i'm thinking fuel presure regulartor. am I right?

You might want to check for any possible vacuum leaks from the back of the intake manifold. A severe enough vacuum leak will cause the engine to spit and sputter. You may also want to check the egr valve stuck in the open position as well. Also caused by possible vacuum issues. Vacuum within the intake will increase with accelaration and if you have a cracked line it could cause the symptoms you are describing.

Good Luck

    As I am not too familiar with the CRX, but by disconnecting the regulator and the vehicle ran better, that would be a good place to start.



    Good Luck

91 Honda CRX HF won't crank
This may sound obvious but have you checked the battery? Batteries are generally considered old if they are over 5 years old. A battery can hold a full charge but struggle when put 'under load'. Starter motors use a lot of power to work. Get it "Load Tested" to see if it needs replacing.

My 1989 Honda CRX the idle jumps when I push on the clutch what causes this
Does your transmission and clutch work perfectly fine, no noise or any problem? I can't imagine why the idle would jump from dis-engaging the clutch from the flywheel. When you do that, the transmission input shaft is no longer turning with the flywheel- it becomes stationary. If the input shaft had worn gears or a worn bearing, I suppose it could put a little load on the engine, make it work harder to maintain rpm's. So when you push the clutch in, that load from turning a worn bearing or gear disappears and your idle increases. How's that for a crazy solution?

Don't know much about crx, but I assume the computer controls idle? If it does, the ecu would have no compensation in idle speed for pushing the clutch pedal down.

84 crx starts fine and idles fine in park and neutral, but dies immediatly when shifted to drive or reverse. Will run very roughly if pumping accelerator. What's going on?
You might want to check the engine for a vacume leak.Once the rpm's drop it may have a big enough vacume leak to not keep it running under a load.

1990 crx base model honda civic want start
I would suggest an ignition module. If it is a rough idle at startup I would check the throttle position sensor. You can check that by starting the car and unplugging the TPS. If the car runs differently then chances are it is working fine.
