Recently my 2000 civic sir (si in the US) has started to hesitate or stutter periodically. It happens between 1500 and 2500 rpm and I beleive it's usually when it's warm, and I'm accelerating from a stop. Any ideas what this could be? You changed the fuel filter? |
Checked air filter?
Had any work done under the hood, where some one could have pulled a
vacuum hose lose?
Changed the fuel cap?

Any ideas what this could be? you'll almost certainly have codes stored in the computer. read them, then report back. |

I floored it and after about two seconds the engine light blinked 5 or 6 times. After about 5 seconds the engine started responding properly and the engine like went away. No codes were saved. don't believe you! how did you try to read them?

(If it has a "Check Engine" light, I won't own it!)

I know it works because we've connected it to other vehicles and it's reported codes on them. in that case, look into the ignition switch. for your model year, there was a recall because the switched burnt out - and symptoms were odd, but left no code like you describe. it's particularly bad if you have a heavy key ring. try using the key on its own and making sure you manually return the key fully to the "run" position after cranking rather than letting it turn back with just the spring. the spring's not very strong, and particularly with a heavy key ring, the contacts only partially engage, overheat, and burn out. and of course, replace the ignition switch if this turns out to be the cause.

They're missfire codes and it turns out the misfire monitor requires 2 consecutive trips to trigger the DTC. The codes are P0303 (Cylinder 3 misfire) and P1399 (Random/Multiple cyclinder misfire). Reported data is as follows: Report#: 1 Report Date: 4-16-2007 (8:34 PM) Vehicle Year: 2000 Vehicle Make: Honda Vehicle Model: Civic (SIR) Vehicle Engine Size: 1.6L Vehicle VIN: Vehicle License Plate: Vehicle Mileage: 1230000 Stored: P0303 Cylinder 3 Misfire Detected Pending: P1399 Random / Multiple Cylinder Misfire Detected MIL ON MisFire Monitor Complete Fuel System Monitor Complete Comprehensive Component Monitor Complete Catalyst Monitor Complete Heated Catalyst Monitor Not Supported Evaporative System Monitor Complete Secondary Air System Monitor Not Supported A/C System Refrigerant Monitor Not Supported Oxygen Sensor Monitor Complete Oxygen Sensor Heater Monitor Complete EGR System Monitor Not Supported DTC for which Freeze Frame was Stored P0303 Fuel System 1 Status Open Loop - due to driving conditions Fuel System 2 Status Not Supported Calculated LOAD Value 94.12 % Engine Coolant Temp 138.20 °F Short Term Fuel Trim - Bank 1 0.00 % Long Term Fuel Trim - Bank 1 -4.69 % Intake Manifold Absolute Pressure 28.05 inHg Engine RPM 3256 rpm Vehicle Speed Sensor 32.93 mph Intake Air Temperature 59.00 °F Absolute Throttle Position 92.55 % check the ignition componentry [distributor cap, rotor, leads and plugs] and ensure its in good condition - if old, suggest replacement as a precaution. random misfire on all cylinders can be multiple problems, but misfire on #3 is injector or ignition componentry. injector cleaner might be a good idea too.
