Rough idle and stalls

Engine Performance problem Two Wheel Drive Automatic 98210 miles

my car runs rough at idle. It started after I did a tune up. Some times the idle is fine, but sometimes it drops just above 500 RPM's

Actually I am a mechanic, and am looking for some help. The car does not have any codes. It had a code P2070 intake manifold control valve stuck open.

The intake manifold valve was changed. Along with the mass air flow meter and coils and wires. The original complain was no power after driving for a while. The dealer diagnosed for all those items, plus the SSV Solenoids.

Thanks for any help you could provide.

Hello -

Okay my friend, let's see if we can get you some assistance here.

The tune up. . .. . ..I didn't see where you changed the plugs. According to the maintenance table plugs should be changed every 35,000 miles. So I would change those for sure. They were due at 70,000.

Next, the fuel filter is to be changed at 100,000 miles. Well, you are at 98K now so I would change that too.

Now for the rest.

I reviewed the TSBs and there is actually one for P2070 and the fix for it. I have attached that for your review.

Next, there are two other TSBs I attached for your review that deal with lack of power. If you want the figures for them let me know and I will take the time to load them. I will first give you the TSBs to review. I figured since 2070 was the code and I wasn't sure about the plugs and filter, do that first.

Your thoughts?

REPAIR PROCEDURE
1. Reboot the IDS to clear memory before reprogramming.
2. Using IDS 53.8 or later software, reprogram the PCM to the latest calibration (refer to CALIBRATION INFORMATION) by following the "Module Reprogramming" procedure.
NOTE: "� Always update the IDS tool first, then follow on-screen instructions to download the needed calibration file for PCM reprogramming.
"� It is not necessary to remove any fuses or relays during PCM reprogramming when the IDS screen prompts you to do so. You may accidentally stop power to one of the PCM terminals and cause the PCM to be blanked, or you may receive error messages during the IDS reprogramming procedure.
"� IDS shows the calibration part numbers after programming the PCM.
"� Please be aware that PCM calibration part numbers and file names listed in any Service Bulletin may change due to future releases of IDS software, and additional revisions made to those calibrations for service related concerns.
"� When reprogramming a PCM, IDS will always display the "latest" calibration P/N available for that vehicle. If any calibration has been revised/updated to contain new information for a new service concern/issue, it will also contain all previously released calibrations.
"� When performing this procedure, we recommend that a battery charger be installed on the vehicle battery and turned ON to a maximum charge of no more than 20 AMPS to keep the vehicle battery up to capacity. If you exceed 20 AMPS, it could damage the VCM.
3. After performing the PCM reprogramming procedure, verify the repair by starting the engine and making sure there are no MIL illumination or abnormal warning lights present.
NOTE: "� If any DTCs should remain after performing DTC erase, diagnose the DTCs according to the appropriate Troubleshooting section of the Workshop Manual.
"� After PCM reprogramming, it is no longer necessary to road test the vehicle to "relearn" KAM (Keep Alive Memory).
4. Fill out an "Authorized Modifications" label (P/N 9999-95-AMDC-97) with the new PCM calibration information, your dealer code, and today's date.
5. Place the "Authorized Modifications" label on the "A" pillar below the tear tag in the driver door jamb. The "Authorized Modification" label will inform technicians of the PCM calibration change if future repairs are necessary.

DESCRIPTION
Some customers may experience a lack of engine power and an low engine idle speed during high ambient temperatures. This may be caused by poor sealing of rotor chambers due to an accumulation of carbon on the rotor housing trocoid surface. This is caused by a lack of metering oil lubrication during engine start or insufficient ignition timing under high ambient temperature condition. A revised PCM calibration is available which increases metering oil lubrication amount during engine start. Ignition timing under high ambient temperature is recalibrated as well.
Customers who are currently experiencing a lack of engine power and low engine idle speed should have their vehicle repaired using the following repair procedure.
IMPORTANT: "� BEFORE PERFORMING THE REPAIR PROCEDURE, ENSURE THE FOLLOWING ITEMS HAVE BEEN COMPLETED:
"� 2004-2006 RX-8 VOLUNTARY EMISSION RECALL CAMPAIGN 4206F
"� MAZDA SPECIAL PROGRAM (MSP16) - ENGINE LACK OF POWER - PCM REFLASH
REPAIR PROCEDURE
There are many possible concerns which may cause lack of power symptoms. The focus of this Service Bulletin is assisting diagnosis of concerns related to the Rotary Engine internal components. While it is impractical to list all possible causes in this Service Bulletin, please inspect the following common concerns which may cause lack of power symptoms before proceeding to Engine Inspection.
"� CATALYTIC CONVERTER - Restriction of the exhaust system due to catalyst failure may cause lack of power symptoms. Check MODE 6 ON BOARD TEST RESULTS and verify catalyst efficiency is within specification.
"� IGNITION COILS - Non-functioning ignition coils may cause lack of power symptoms. Inspect ignition coils using Service Bulletin 01-016/07 IGNITION COIL INSPECTION. Replace non-functioning ignition coils and test drive the vehicle to confirm lack of power symptom has been repaired.
Fig. 1: View Of Test Result Value Chart
Courtesy of MAZDA MOTORS CORP.
Is the measured test result VALUE number MORE or LESS than 4.60:1?
"� LESS THAN 4.60:1 - Catalytic converter OK, replacement is NOT necessary.
"� MORE THAN 4.60:1 - Catalytic converter failed, replace catalytic converter and check exhaust system for restriction by broken material. Test drive the vehicle to confirm lack of power symptom has been repaired.
"� SECONDARY SHUTTER VALVE (SSV) - Lack of power may be caused by a stuckclosed Secondary Shutter Valve (SSV). This condition prevents intake airflow into the engine during mid and high RPM. Confirm the SSV moves freely and is not stuck in the closed position. The vehicle may also have P2070 (SSV stuck open) stored in PCM memory. Review Electronic Service Information for the latest Service Bulletins and / or consult workshop manual for current repair procedures.
Lack of power symptoms typically occur during hot ambient temperature conditions. Please perform the following engine diagnostics tests when the customer has a current lack of power complaint and / or during hot ambient temperatures for accurate results AFTER inspecting the above listed components.
