Incidentally, that Renaultsport 172 deserves a special mention, because it looks as though it could well be the new king of the hot hatches, thanks to the blistering performance provided by its 172bhp, two-litre, 16-valve engine and lowered chassis. We’ve driven it and will be reporting on it in due This new twin-cam unit is already used in the Megane and Scenic and certainly deserves this wider application because it’s a real little sweetie, whose “warm hatch” performance belies its capacity – curious that Renault insists that size matters! While happy to tip-toe through traffic, it really comes alive out on the open road. Not only is it smooth and quiet, but take it beyond 3000rpm and it’s a decidedly swift performer that loves to rev yet still manages to remain mechanically refined. Complementing the new engine are the deft gearchange and nicely weighted clutch that give added driving pleasure. Such is the way that the powertrain is mounted, however, that the gear lever gives an unseemly lurch forward as you back off the accelerator

The high-speed idle screw is factory sealed and cannot be adjusted. Low-speed idle can be adjusted. 1. Use an optical tachometer such as Snap-on No. MT139 or MTE (Cummins tool division) No. 3377462 to read the engine RPM. 2. Bring the engine to normal operating temperature. 3. Adjust the low idle speed at the low idle speed screw. The screw and locknut are located at the rear of the fuel injection pump. 4. Loosen the idle screw lock nut. Adjust idle screw to obtain specified RPM. LOW IDLE SPEED With automatic transmission: 750-800 RPM with transmission in drive and air conditioning on. With manual transmission: * 780 RPM with transmission in neutral and air conditioning on. * With engine at operating temperature. HIGH IDLE SPEED Do not attempt to adjust high idle speed. High idle speed adjustment screw is factory sealed. Breaking seal will void injection pump warranty 5. Tighten the locknut after adjustment.

NOTE: If DTC P1519 is stored at same time as DTC P0505, troubleshoot DTC P1519 first, then recheck for DTC P0505. 1. Start the engine. Hold the engine at 3,000 rpm with no load (in Park or neutral) until the radiator fan comes on. 2. Check the engine speed at idle with no-load conditions: headlights, blower fan, rear window defogger, radiator fan, and air conditioner off. Is the engine running at 730+/-50 rpm? YES – Intermittent failure, system is OK at this time.? NO – If the idle speed is less than 680 rpm, go to step 3; if it’s 780 rpm or higher, go to step 4. 3. Disconnect the idle air control (IAC) valve 3P connector. Does the engine speed increase or fluctuate? YES – Adjust the idle speed. If the idle will not adjust properly, clean the passage in the throttle body, and then adjust the idle.? NO – Replace the IAC valve.? 4. Turn the ignition switch OFF. 5. Remove the intake air duct from the throttle body. 6. Start the engine and let it idle. 7. Put your finger on the lower port (A) in the throttle body. Does the engine speed drop below 780 rpm? YES – Adjust the idle speed. If the idle will not adjust properly, replace the IAC valve, and then adjust the idle.? NO – With the throttle valve completely closed, check for vacuum leaks, and repair as necessary.?

In cases such as the above, the cause is probably the air/fuel mixture or idle air control motor. Other systems affecting idle quality include the ignition system and compression. TROUBLESHOOTING HINTS (The most likely causes for this case:) Malfunction of the ignition system. Malfunction of air/fuel ratio control system. Malfunction of the IAC system. Malfunction of the evaporative emission purge solenoid system. Poor compression pressure. Vacuum leak. Malfunction of the EGR solenoid system. STEP 1. Check if the battery terminal is disconnected. Q: Has the battery terminal been disconnected lately? YES: Start the engine and let it run at idle for approximate 10 minutes after engine warm up. Then, if a malfunction occurs, go to Step 2. NO: Go to Step 2. STEP 2. Using scan tool MB991502, read the diagnostic trouble code (DTC). CAUTION: To prevent damage to scan tool MB991502, always turn the ignition switch is to the “LOCK” (OFF) position before connecting or disconnecting scan tool MB991502. 1. 2. 3. 4. Connect scan tool MB991502 to the data link connector. Turn the ignition switch to the “ON” position. Read the DTC. Turn the ignition switch to the “LOCK” (OFF) position. Q: Is the DTC is output? YES: Refer to Diagnostic Trouble Code Chart. NO: Go to Step 3. STEP 3. Check the engine idling state. Q: Is it hunting remarkably? YES: Go to Step 4. NO: Go to Step 5. STEP 4. Check the following items. 1. Carry out the following cleaning. a. Clean the throttle valve area. 2. After cleaning, confirm that the malfunction symptom is eliminated.
