Question about 2006 Suzuki Forenza

Open Question

My 2006 Suzuki Swift automatic bucks and jerks and rough idles when sitting at idle and the transmission is set in drive. This does this whether the button switch is set in the econo or normal mode for gas savings To stop this bucking or rough idle, I have to move the transmission to idle. If the dealership looks at it, they do something which only lasts about a week. The car is an EU car located in Budapest, Hungary.

My 1994 GTi was doing the same thing. The car should idle a bit fast when cold, say 1500rpm, due to the auto-choke. However, 2800rpm is too high. I had a look at my throttle system and could not workout how to adjust the auto-choke idle speed seperate from the normal idle. So I reluctantly had it serviced by the agents, they cleaned out the throttle body and adjusted it. It is better, 1900rpm, but still a bit high for my liking.

SOURCE: bucking while idling

Have the upper and lower intake manifold checked. It needs to be a cold start. 2000's are notorious for having the gaskets crack and leak. This may be causing the engine to idle rough at start-up ans somewhat disappear after warming. Winter starts can shake the steering wheel!

P.s. I had it fixed at 65,000 miles (warranty), and am having it fixed again at $120,000 miles.

SOURCE: how to fix an idle problem in my car

most cars have whats called the IAC (Idle Air Control) sensor, but other sensors can cause the same problem. fords have a bad problem with these sensors. keep in mind it is not always a sensor, but in most cases this is a successful fix. good luck!

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.

Car jerks sometimes when going from P to R


It's the transmission sensor. I've had mine replaced three times now. You can fix it (see this thread: http://www.suzuki-forums.com/suzuki-forenza-reno-forum/35284-transmission-range-sensor-all-you-need.html) and please report it to Suzuki at 1-800-934-0934

Jeep cherokee jerks when shift into overdrive going 45 mph


If the engine has a rough idle you know you have a miss-fire or other problem with one or more cylinders.
When you shift into overdrive the engine is working harder than in normal drive because of the lower torque/RPM.
So any slight miss under normal conditions will be magnified in overdrive or with the ac on.
See if you can nail down the cause for the rough idle.

2006 mercedes benz CLS500 rough idling


There are several reasons why the vehicle could be rough idling. If no check engine light is on and the vehicle feels like it's idling rough when you put it into gear. The transmission mount may be worn out which cause the vehicle to feel like it has a rough idle. Definitely at minimum you will feel the vibration when sitting in the vehicle.

Recurring Mystery Problem in a 1986 Suzuki Alto. (Idle related)


Bad fuel, water in the fuel, dirt in the fuel.

Drain the fuel tank completely.

Pour in a gallon or two of fresh fuel.

See how it goes.

Put some of the old fuel in a glass bottle, hold it up in front of a light and see if you can see any foreign material in it...

Bucking while idling


You want to check your charging system. Take a reading at the battery and see what you get. it should be 13.5-14 volts. Check the volts at the cables. with the battery hook up take a reading at the cables. if there is a big difference between the cables and the battery then you need to clean and tighten your cables. If the volts are less then I said before then you need to have your alternator checked.
