    91 Civic Lx half shaft ID

    I checked the honda parts guide and they call the thing a driveshaft L or is there a space between drive and shaft? Anyway it most certainly is the SOHC 4 speed automatic and the shaft on the drivers side. Vendors are calling it driveshaft, axle shaft, cv shaft, half shaft, and the list goes...

    91 Civic Lx half shaft ID

    My 91 Civic LX has a torn outboard CV boot on the driver's side. I am advised to replace the half shaft as a unit. When I go to order the shaft I am faced with a choice of different shafts based on the number of splines. Is there a way to check which shaft is right for my car without pulling...

    Stuck 91LX Hood

    My hood release has been getting harder and harder to pull to get the hood to release. Recently I put some petroleum yelly on the plunger and moving plate it engages-worked well for a few times and now I'm stuck! I can pull the wire a good long way and lots of resistance but no pop!

    91 TB Fuel pressure regulator source

    I've had a long list of problems with my 1991 civic LX and now have just one last issue-the fuel pressure regulator. I can't seem to locate one that works correctly. All the ones I buy that claim direct fit run 45 PSI when tested-they may come in any one of many suppliers boxes but in the end it...

    Engine Trouble.. O2 Sensor?

    The timing is good-I do not know how to test the FPR-also my manual only gives a volumetric test for the fuel pump. Were would I tie in to do a fuel pressure test? For arguments sake if the FPR and fuel pressure are good were would I go next?

    Engine Trouble.. O2 Sensor?

    Running without the O2 sensor the car runs a little worse than with the new sensor. So then there is an other problem yet to solve. The only code is when I run without the O2 sensor-codes for O2 sensor. The only things left I can guess is the intake temp-the MAP, the crank angle/crank speed.

    Engine Trouble.. O2 Sensor?

    My 1991 civic lx runs poorly between 1500 and 2000 rpms-It runs lean . Cold start it runs perfect but in a minute or two it runs poor between 1500 and 2500rpms. I replaced the original O2 sensor and it improved some. The problem became worse over time and on your recommendation I unplugged the...

    Engine Trouble.. O2 Sensor?

    I have replaced my O2 sensor twice now and the first time I used a generic sensor-only improved a bit. The second one was an aftermarket and the improvement was much more-- but still I have some problems at 1500 to 2000 rpms. I noted that the Honda O2 sensor from Honda is $200.00 -maybe they...

    Engine Trouble.. O2 Sensor?

    I have not replaced the fuel filter-I can tell that that is not at issue-I can run 2500 to red line just fine, if the filter was clogged the motor would starve more and more as rpm's and load increases instead it improves at 2500 rpms suddenly!! The problem stops, and it runs perfectly from...

    I have replaced both the fan switch and the transducer-just recently I replaced the transducer again that is the temp sensor by the distributor. The water leak is due to a pump/block problem that has not been fully stopable after 3 waterpumps now-I run on stop leak and peiodic refills. The...

    Vandalized ignition-can't recover trouble codes 91 Civic

    If I follow you right there should be a voltage sent to the ecu from the relay and that is the one hope other than brain toast. I have stripped the ecu frorm the floor pannel and could test the harness for voltage and ground if you can guide me to the suspect wires /pins. Otherwise I was...

    I don't know how can I check? The vandal pulled the rear seat to open the tank and steal the gas --can it be listened for? I can tell you this it was 3 hours after heat up that I tried to start and it craped out instead- 4 hours latter I retried and started right up. The motor was hardly at all...
