You have a fuel presure sensor or vacuum problem.
Check Gas cap as well.
You will need a multimeter for some tests.

Why a 1997 honda civic engine surges at idle


which engine, options there are many.???
cant fix any engine, until you know what it there.
a civic not Tacoma. as posted.
see end for engines ????

surge 101 (running gasoline?)
it caused by 2 things. (and lots of reasons)
1: engine running lean. all engines lean surge. fix that first.
hint use a scan tool see live data........?????
2: ISC system is faulting, the idle speed controller can fail for #1
or for itself. (it can stick) clean in.


wiki list of engines. (which one???????????????)_
The sixth generation featured engine options were available along with their first Natural Gas Powered Civic, the GX. From 1996-2000 the Civic was sold under the CX, DX, EX, EXR, HX, LX, and for Canada, SE, and Si trims; all base models were made with 1.6L engines. The EX-CX are all SOHC (Honda D engine). The CX, DX, and LX all have D16y7 non-VTEC engines; whereas the EX has a D16y8 VTEC, and the HX has D16y5 VTEC-E. The USDM Si and Canadian SiR came with a DOHC (B16A2 VTEC). The first civic SI coupe EM1 was introduced in 1999 until 2000. Europe saw a DOHC 1.6 VTI hatch and sedan and a DOHC 1.8VTI engine was available for the Domani related five-door liftback and esta

Could it be that the ecu is wrong


No it is not Catalytic Converter related. Your fuel tank pressure sensor must be disconnected or the wiring to it defective for the evaporative emission system.

DTC P0446 - Evaporative Emmission Control System Vent Control Circuit
Evap vent valve has only one purpose. It closes in order to seal the vent so the EVAP system can pressurize and ensure there are no leaks. Evap vent valve is usually supplied Batt. voltage with key on. The ECM's driver controls the ground, and when grounded, activates the valve (closing it). If the ECM detects a short to ground, and open,or a short to battery voltage on the control circuit, P0446 will set. Code also may refer to ECM detecting that EVAP system is unable to achieve or maintain vacuum during test. A code P0446 could mean one or more of the following has happened:
  • Faulty vent valve
  • Open, short or excessive resistance on Vent valve control circuit
  • Blockage of vent valve
  • Bad PCM
Possible Solutions
  • Replace Vent valve
  • Repair open, short, or resistance problem in control circuit
  • Repair open, or short, or resistance problem in power circuit
  • Replace PCM

DTC P0452 - Evaporative emission control system, pressure sensor low imput
DTC P0453 - Evaporative emission control system, pressure sensor high imput

The PCM monitors the EVAP control system FTP sensor input signal to the PCM. The test fails when the signal average jumps above a minimum allowable calibrated parameter. If both codes are present, it sounds like your fuel tank pressure sensor has failed.

The sensor is on top of the tank and you will have to remove the tank. But your symptoms are pointing to more than just the sensor. You may have wiring problems.


Hope this helps (remember to rate and leave a comment about this free answer).

they are all emission faults

P0453 OBD-II Trouble Code: Evaporative Emission Control Pressure Sensor High Input. P0453 code means that a reading from the engine's evaporative pressure sensor is higher than normal due to fuel tank vapor leaks into the system.

saturated carbon canister
sensor faulty
rubber evap hoses at the tank perished

idea
check the tank fuel cap seal is working
replace the cap is one possible cause

check the fuel pump pressure or for injector rail leak
P0446 Evaporative Emission Control System Vent Control Circuit Malfunction. The code P0446 is set when the engine computer recognizes a fault or restriction at the vent control part of the Evaporative emission control system (EVAP).

The Code P0452 indicates that the Evaporative Pressure Sensor is indicating pressure change values that are below specification, during the EVAP Monitor test and/or the operation of the vehicle.
