1988 Acura Integra Stalling

Hello Vince, I have a 1988 Acura Integra RS 5 speed with 330,000 miles. It still gives good mileage after all these years - 30 mpg average. 2 months ago it started stalling. Whenever I would try to start moving from a stop I feel the engine is not responding to the gas pedal, rpm would go below 500. As soon as I release the accelerator it goes back to 700 rpm.

As I try to move again and not release the accelerator the engine dies. Then I have a hard time starting the engine. After a few tries, the engine starts but I have to rev up to about 3,000 rpm so the engine won't die and I get my car moving. Stalling does not happen when the car is in motion. It only happens when I come to a stop and then try to move forward.

I checked the coolant temperature sensor and the MAP sensor to be okay. But it still stalls after I try moving from a stop. Was I looking in the wrong places ?

What did I miss?

Thanks...

Answer:

The first thing you should do is check the part number on the igniter. If it is anything but 06302-PT2-000 replace it with that part number. Check with your dealer first, there was a recall and they may replace it for free. If not get a copy of TSB number 93-003, the parts listed on it and you can replace it yourself.

Check the ECU for codes. Turn the ignition on, move the front passenger seat to the rear position and observe the LED on the front of the ECU. The LED indicates a system failure code by blinking frequency. The ECU LED can indicate any number of simultaneous component problems by blinking separate codes, one after another.

If Red LED indicates CODE 11, 16 or exceeds 18, count the number of blinks again, if the indicator is in fact blinking these codes, or is not on or stays on without blinking, substitute a known-good ECU and recheck. If the indication goes away, replace the original ECU. Here is the code chart...

• 1 Primary Oxygen Sensor (HO2S) (Sensor 1).
• 2 Rear Heated Oxygen Sensor.
• 3 Manifold Absolute Pressure Sensor (MAP).
• 4 Crankshaft Position Sensor (CKP).
• 5 Manifold Absolute Pressure Sensor (MAP).
• 6 Engine Coolant Temperature (ECT Sensor).
• 7 Throttle Position Sensor.
• 8 Top Dead Center Position Sensor (TDC).
• 9 No. 1 Cylinder Position Sensor (CYP).
• 10 Intake Air Temperature (IAT) Sensor.
• 12 Exhaust Gas Recirculation (EGR) System.
• 13 Barometric Pressure (BARO) Sensor
• 14 Idle Air Control (IAC) Valve.
• 15 Ignition Output Signal.
• 17 Vehicle Speed Sensor (VSS).
• 18 Ignition Timing Adjuster).

If that fails to turn up anything you might have a clogged fuel filter, bad Idle Air Control Valve, MAP sensor (recheck it) or a bad Vehicle Speed Sensor.
