If the timing marks are aligned properly and you rechecked the timing. Check that a vacuum line didn't fall off. After a belt replacement always recheck the ignition timing it will change. But if it ran smooth before timing or a line is off.

You may of bent a valve. You will need to do a compression test. You should of removed the head to have it inspected. Also make sure you have no vacuum leaks. spray water around anything that can **** air in. If you have been driving you most likely set a misfire code which would indicate which cylinder is the issue. even if the check engine light is off you may still have a code stored in memory.

SOURCE: Rough idle

Check O2 sensor and MAF sensor.

The best thing to do is scanning car computer with OBD II reader, that will tell you what is wrong.

SOURCE: rough idle after timing belt change what can it

if over 80,000 miles it could be exhaust system or catalytic converter. If it has been idling rough since you got the belt changed, I would contact the mechanic and just ask. Are the rpm's moving up and down or at all?

SOURCE: The idle is rough. If you give it gas the engine

The symptoms you describe are consistent with a mass airflow problems. Take note that the 1998/2002 Accords do not have a MAF (mass airflow sensor) but rather, a MAP sensor. Take this unit out and clean it with electrical circuit spray cleaner. Its best NOT to wipe the sensor dry after cleaning, because the liquid will evaporate by itself, and you will reduce the possibility of damaging the delicate printed circuits.
After cleaning and reinstalling, disconnect the negative terminal of the battery, so that the computer (ECM) resets itself and gathers the new readings from the sensor to adjust the mixture. IF the sensor has failed, and need to be replaced, the check engine light should be on.

We done change the timing belt how come the idle is too rough

Was the idle rough before you changed the timing belt? If yes, check for other conditions such as a stuck fuel injector or ignition system issues. If no, the timing marks weren't properly aligned when you put the new timing belt on, and you're off by a tooth or more.

2007 chevy uplander running real rough, what could it be?

Vacuum Hoses
  • A loose or broken vacuum hose causes rough idling, and is the easiest repair of all. This is a very common problem since hoses wear out over time. Look in your engine compartment, and examine the hoses carefully for any signs of abrasion, breaking or loosening. Replace any damaged or broken sections of hose, available at most auto parts stores, and your rough idling will more than likely disappear.
Clogged Filters
  • Clogged filters are another common cause of rough idling. Inspect your air filter. If dirty, replace it. Also, a clogged fuel filter causes rough idling. It's hard to tell if a fuel filter is clogged or not, so a good rule of thumb is to change it at every general tune-up.

Electrical Components
  • Bad spark plugs, bad spark plug wires and a bad distributor cap are other common causes of rough idling. If it has been a while since you changed these components, do so. Most auto service centers can do this for you if you need technical expertise.
Timing Belt
  • A timing belt jumping a tooth is also a cause of rough idling. This throws off cam timing, setting in motion a series of events that prevent your engine from achieving proper timing. This is a more in-depth repair and, if needed, should be referred to a qualified auto mechanic.

05 jetta 2.5, what are some problems you get if the timing belt is bad

If it is bad? I don't think it go's bad. It will break then it wont start. When you try to start it the engine turns over very fast. If it jumps a tooth on timing then it will spit and sputter. Backfiring either in the throttle body or exaust. Or both.

Vw lt46 1998 would it damage valves if timing belt

yes it will and most likely put a hole in the piston and snap the cam shaft if the engine is doing any more than idle speed, if it breaks at idle you may be lucky and just get away with a few bent valves but if im honest ive never seen anyone be lucky with one the normaly require a new engine. also worth changing the water pump at the same time as these do seize and will snap the new cam belt ! the only belt you can get away with leaving is the pump belt if this breaks no damage is caused the engine will just cut out ! however you will need to pretty much remove it after fitting a cambelt to set the timing so its pretty pointless no to change it

How do I know when it's time to replace a timing belt on my 2003 Sorento? A local mechanic said it idles rough because the teeth are breaking off on the belt. How would he know that by just replacing spark...

It's unlikely that the cam belt would cause rough idle!!
normally you would change the cambelt after so many miles Mine are always changed after 30k miles regardless. The mechanic was purley guessing.

If the idle is rough then it will be an electronic fault like air flow meter,EGR valve, Idle control unit. etc

Get back to me if you need more info.

When should timing belt be changed on hyundai accent, also what are indications that it is going bad

Hyundai recommends changing the timing belt every 60K miles. As far as symptoms go, a timing belt won't give a lot of warming prior to breaking but a few would be extremely rough idling and misfiring. You should know that a broken timing belt often will do damage to the engine. I hope you find this answers your question. All the best!
