Possible intake gasket leak causing a misfire, or plugs or coil causing a misfire. each cylinder has its own coil. You can hear the vaccuum leak with your ears under hood if gasket is bad. Check eng codes at advance auto prob for free. If it has misfire codes only, prob coil or plugs. If misfire with fuel trim, prob gasket.

Rough idle in drive, correct rpm


Car idle is rough Inspection Service & Cost A rough idling engine can be caused by a number of issues, some of them are serious while others tend to be minor, but the symptoms remain pretty much the same. The car will feel rough and bouncy when the engine is running. The car will also idle below its regular speed, display inconsistent RPMs and may produce a shaking, skipping or slipping sound when the vehicle is running.
While a rough idling engine may seem to be a simple inconvenience it often indicates a deeper problem within the engine. The vehicle should be inspected and repaired as soon as possible because small problems have a way of turning into expensive repairs. How this system works: The idle speed of an engine is basically the rotational speed the engine runs on when it is un-coupled from the drivetrain and the throttle pedal is not being depressed. The idle speed is measured in the revolutions per minute of the crankshaft.
When an engine is running at idle speed it generates enough power to smoothly operate equipment such as the water pump, alternator, and power steering but not enough power to move the vehicle itself. A passenger car will usually idle between 600 RPMs and 1000 RPMs. A properly functioning idle should run smoothly without skipping or slipping. Common reasons for this to happen:
  • Dirty Fuel Injectors: The fuel injection system injects fuel into the cylinders, which creates a mix of air, and fuel to ignite and burn. Fuel injectors have tiny nozzles to spray the fuel into the cylinder and they can become clogged over time. clogged or failing fuel injector creates a lack of fuel in the vehicle's engine. This can cause a rough idle, it can also cause symptoms such as slow acceleration or the car not feeling as if it has enough power. If the problem is addressed early, it is possible to clean the injectors, which will restore them to full function. If this condition is not addressed in a timely manner the injectors will need to be replaced. Incorrect Idle Speed: While the average idle speed falls between 600 to 1,000 RPMs, if your vehicle is experiencing a rough idle it could be due to an incorrect idle speed setting. A trained mechanic can easily adjust the idle speed, and it should stay at the proper speed. If an adjusted idle speed becomes inconsistent or changes at random intervals there may be a bigger problem that needs to be explored. Vacuum Leak: If the vacuum system has a leak, it can seriously affect the ability of the vehicle's computer to regulate the air to fuel ratio. This can lead to a rough idle and if the problem is not addressed the car may experience slow acceleration and a lack of power. Vacuum leaks should be inspected and repaired immediately. Incorrectly Installed or Damaged Plugs: Spark plugs are responsible for creating the spark that allows the vehicle to burn fuel. If spark plugs are improperly installed or malfunctioning, the idle speed can be affected. The vehicle's engine may vibrate or there may be slipping or straining sounds coming from the engine. Defective or Clogged Fuel Pump: A rough idle can be related to fuel delivery issues. The fuel pump, which is responsible for pulling fuel from the gas tank to the fuel injectors, can become clogged or defective. If this happens the engine will not get enough fuel, which can cause a rough idle, sputtering, stalling and even slow acceleration. Clogged Fuel Filter: A clogged fuel filter can cause similar problems. The job of the fuel filter is to screen out contaminants in the fuel, over time it will become clogged and need to be replaced. A rough idle is one symptom of a clogged fuel filter. Failing Electrical Components: A problem or failure in the ignition system or various electronic components can cause a rough idle. If this is the case, the problem will usually get worse as RPMs increase. Common culprits include the ignition control module, plug wires, coils, and spark plugs. Defective Airflow Sensor: A defective airflow sensor can be responsible for a rough idle. A mass airflow sensor detects the amount of air coming into the fuel injection system and sends that information to the vehicle's computer. The computer uses that data to deliver the proper amount of fuel to the air in the vehicle. Over time these sensors can malfunction or become dirty. One of the first symptoms of a malfunctioning airflow sensor is a rough idle. The car may also accelerate slowly and even stutter or stall as the problem progresses. Dirty Oxygen Sensor: Oxygen sensors measure how rich or lean the gases are as they exit the combustion chamber. Depending on the results, the amount of fuel entering the engine is adjusted by the vehicle computer. The ultimate goal is to maintain an ideal mixture that produces the lowest emissions. A dirty or failing oxygen sensor will usually trigger the check engine light and can lead to a rough idle, lower fuel efficiency and failed emission test.

Here's a link to a picture of what the EGR look's like,it's at the back of the engine,easy to remove.When bad, vehicles can experience poor engine performance, poor idle, high NOx emissions, failed emissions test, hesitation, engine surging http://www.autozone.com/emission-control-and-exhaust/egr-valve/duralast-egr-valve/volvo/960/1995/6-cylinders-9-2-9l-efi-dohc/857098_162245_0

How do I fix, bad idle in suzuki swift , check light on, no codes.


the title is contradiction
" check light on, no codes."<< totally wrong
scan it one more time with a REAL scan tool this time. (there are DTC errors , or codes as you said)

what does bad idle mean? misfiring, or idle speed too low
or too high? RPM, or
surging?

say what that means please.
and more important is engine hot or cold ? failing.???? or both????
there are over 50 causes.
but can be broken down to simple physics and gauges.
1: engine bad, lost compression.
2: engine cant breath, dirty air cleaner
3: ISC stuck closed or open or just stuck. (bad idle air supply)
4: bad spark, 1 or all 4 (never had a tune in this decade.
5: cam drive, slipped (belt) causing #1 failure.
6: air fuel mix too lean, and causes rpm drop and ISC fails.
7: air fuel mix too rich and misfires.
8: egr stuck open, it misfires and ISC gives up.
9: cat clogged, engine cant breath #2 like.
10: and the vast other reasons for misfire.

we cant drive it, see it or hear it misfire, so.....????

there is a test for all 10, ask. or get car serviced.

Runs rough idle


your idle valve may be dirty or needs replacing would check this as it controls idle. sits on the intake with wires coming out of it.

Check engine light on, vibration at idle


Generally, the problem is in the emissions or something that is affecting the effectiveness of the emissions, but other causes can trigger the light to come on, too. To determine the cause, the vehicle will need to be taken to AutoZone or a shop that has an OBD2 scanner, or for 1995 and earlier models, an OBD1 scanner, While a scanner will not give you the magic answer, it will give you a code that narrows down the problem area.
Some specific causes for the light to be on are:
Gas cap left off, not tightened, not installed correctly, or needs to be replaced.
02 sensor.
Engine misfire - error might clear itself after 3 complete warm-up cycles; not restarts, but warm-ups.
At start up for a bulb check - Should not stay on.

Car rough idling causes
misfiring engine is among the most common causes of a rough idle. You may notice your car idling roughly when it's in "Park" or when you're driving it and stop at a stoplight. A rough idle can be caused by damaged spark plugs or spark plug wires or a burned-out valve. It's important to address the cause as soon as possible to avoid potentially damaging the engine. Engine repairs are almost always expensive.

Check engine light (emission system service required) Help?!?!


There may be problem with the mass air flow sensor (very common with Volvo). This causes the fuel system to malfunction.

You may have noticed increased fuel consumption, loss of power and general 'lazyness'.

Better to take it to authorized Volvo service for a checkup/fix.

Lack of power and rough idle


Is your "check engine" or "service engine soon" light on? Lacking power is usually an emission system problem, for instance possibly a bad EGR valve or mass air flow senser. O2 sensers are common to fault but normally doesn't cause power loss usually causes alittle rough idle. Could even be a pluged catalic converter to. have the truck plugged into a scanner, that will tell you the trouble codes and fault info.
