Accent LC (2000-05) :: 2004 1.6L Rough Idle After Timing Belt Change But No Power Loss
Sep 21, 2011
2004 Accent 1.6L
Changed the timing belt and water pump this past weekend. I made sure the timing marks aligned before I put the belts on. They were still aligned after turning the engine by hand and still aligned after taking the car out for a test drive. I did not notice rough idle when I started the engine in the garage nor did I notice a rough idle during the test drive.
A few days later I am now noticing the car will idle roughly when I come to a stop. The idle will get rough enough to gently shake the car. No engine light and no unusual noise from the engine.
I am going to check the timing marks again tonight. I suspect the belt may actually be off by one tooth. I have driven over 100 miles since changing the belt so I don't believe it is off anymore than one tooth or else I presume I'd probably have already broken down or been hearing unusual noises.
Furthermore, I do not seem to have any loss in power. I still have good acceleration and no roughness unless at idle engine speed. I do, however, run rough at higher speeds (75+ mph) on the highway, but this was present before the timing belt change. Unfortunately the car does not have an RPM gauge.
Having said all of this, are there any other possible reasons why I might be idling rough now?

I just changed the timing belt and everything runs great. I pushed the AC button and no light came on. I checked all the fuses and they are good I took the H and L caps of and tapped the pin and there was air blasting out. Don't know what it could be? All I did was loosen the compressor and remove the belt and put it back on.

My mechanic just did the timing bet, water pump and other belts. Also changed the tensioner.
Car runs fine and everything seems great until I get to a red light. The engine sounds louder then before. Not very loud but its louder and maybe a very slight vibration, not sure yet. No noises while driving, seems like its running the same or better then before. Runs fine though

My wife and I recently bought a 2005 Subaru Outback 2.5 XT with an automatic transmission. Last week, we had the timing belt changed by a mechanic I've gone to for the past four years and trust a great deal. He changed the timing belt, drive belts, water pump, pulleys, tensioner and a few hoses, and everything seemed to go off without a hitch. After picking up the car, though, we noticed that the idle seemed much rougher than it had in the past. We can't tell if it's also rough during driving, or when the car is in park or neutral, but there is definitely considerably more vibration when the car is stopped in drive and idling--you can feel it throughout the car. I haven't noticed it until the car has warmed up.
I asked my brother, who is a mechanic in another state, if he had any thoughts, and he said it could be that the belt is off a notch, a vacuum leak or an unplugged sensor. I brought the car back to the mechanic today to see if it he could fix it, and he said that the CEL would be on if it was a vacuum leak or unplugged sensor, and that the car has an automatic idle that the belt change would not have adjusted. He asked if the vibration was getting any better, since when the battery was unplugged it would take the computer awhile to relearn the correct idle, but we've driven it a few hundred miles and it hasn't gotten any better. I left the car with him to take a look at it, but he just called and said he couldn't find anything wrong.
I want to chalk this up to us imagining something, but we both have no doubt that there has been considerably more vibration at least when the car is idling since we picked it up after the timing belt change. Is there anything else that it could be or that I should ask my mechanic?

I have a 00 Accent with 132k miles, I replaced the motor a year ago with a correct 2000 Hyundai 1.5 with 50k miles. I replaced everything that I could at the time, timing belt , starter, water pump, and clutch. It has been running fantastic getting 40 miles per gallon with zero problems , However in the last week I have noticed a rough idle that seems to miss with a vibration that it didn't have before. I have a noticeable loss of power and torque. My miles per gallon has also dropped to about 25 mpg. My check engine light is not on. I will check the plugs and change the air filter today but I would like to know what else could be causing the problem as I am not really sure what to check.

My dad changed the timing belt on my 99 CR-V in August and he had some trouble getting it in time (he had to tear down and put it back together 3 times!). Sometime after the timing belt/water pump/spark plug change, I noticed a vibration in the steering wheel while at a stop and a loss of MPG (went from getting 24 mpg to 22.7).
It did not happen immediately after the timing belt change (or at least i dont think it did) so i thought the mpg loss might be due to the changing weather and the vibration coming from a motor mount that i knew was broken, but I got the motor mount fixed and it did not do anything. I think that the vibration has gotten worse, but it seems to be at its worst when the car is really cold. (this morning the temp. was 9 degrees and it vibrated harder than it ever has).
The vibration only happens when the car is in park or at a stop, and it goes away when i accelerate, even if I only accelerate a little bit. I have not noticed a loss in power, or any sluggishness in acceleration. I have tried to research this, and I read something about the drive belt being out of time, but I'm not savvy with cars so I just don't know.
What could be the cause, do I HAVE to get it fixed, and what do you think a reasonable cost to repair is?

2000 Mazda Protege 1.6l Just replaced timing belt, tensioner, idler, water pump, plugs and coil packs
I have checked the timing about 10 times before puting everything back together by rotating the engin clockwise. No stiff point and marks lining up perfectly every time.
Though when I turn the key in the ignition, the engine cranks but doesn't start.
Can't really check the sparks cause I am on my own, but seems like the spark plugs in 1 and 3 are wet with fuel and 2 and 4 are dry.

I just finished replacing my timing belt, water pump and all belts. I made sure to double check the timing marks lined up via this pic:
Timing belt diagram
I put everything back together and no go. I am not sure what to do now. Should the crank sprocket pulley be in a special starting position? I see is has a "1" engraved on it.

The timing belt went out at idle while making a turn. I changed the timing belt, but when cranked you have to pump the gas to keep it running and it is really rough running with a smell of gas when you turn it off. On the last run it backfired slightly. There is no knocking or pinging. And have triple checked the timing. Could improper torque on the crankshaft bolt cause this or failed ignition coils?

I was wondering if the timing belt on my 05 RX 330 needed to be changed due to age and not miles. The car only has 72k miles on it but it is 10 years old.

Is there a "how to" on adjusting the tension of the timing belt in a 2002 accent 1.5L ....

My car has 103000 miles on it and the timing belt was replaced several hundred miles ago. After the service I noticed it had a bit of a rough idle and a very slight sputtering noise, but still no check engine light. Was the timing belt put on wrong? The engine is non-interference, by the way.

I have 130K miles on my Santa Fe. I just replaced the timing belt without the water pump being replaced. Picked it up from the mechanic and the check engine light was on and it was idling very rough. Left it there for him to recheck. He said maybe he didn't plug in the Cam Sensor all the way or at all. Next day he called me and said that the cam sensor was bad and he replaced it for free. Picked up the vehicle and the idle was a little rough but got worse on the ride home.

After timing belt change code P0016 with Check engine light trac off and VSC light on.
Put on the entire kit...timing belt,tensioner, idler, and water pump. When I took it apart to put the new cam crank sensor I inspected everything and all looked good.
Changed the sensor and reset code, a few hours later back on. Car seems to run fine. I didn't think the sensor was bad. Car was running great...just due for timing belt.

I have 2004 Chrysler Sebring base model 4 cylinder with 90,000 miles. Paid off long ago. The schedule says its time to change the timing belt but no symptoms. No other issues and have kept up the maintenance. The cost is around $1000. I need the car to last 2 more years until our new car is paid off. Should I do the repair or play the odds that it won't break down?

I bought a 02 accent base model hb 5 speed 109k miles for a winter car (have a mustang in garage.) It ran good until tonight when the timing belt snapped. I know this because while driving it made some ticking noises and then shut off and when you try to start it the noise that comes indicates no compression so the belt must've snapped and bent the valves.

my f150 running right so i can enjoy it like everyone else does. I have a 2005 Ford f150 with a 5.4 auto.
It has a rough idle(shakes the truck), very little power, and poor gas mileage. Randomly It will throw a code for misfire on 1 and/or 3 on start up only. It does seem to perform better within the first few of starting but dies right off after that. In fact i got stuck in the snow the other day and it could barely break the tires loose to try and get it out (almost put in 4low cause i didn't want to hurt the trans). I have replaced:
Cats
Fuel pump
Plugs (motorcraft)
Random Coils
Did the timing chains and phasers
MAF
All new injectors
Intake gasket
Was at my mechanics and had a scanner on it and at idle the 1-4 cylinders are all show a negative cylinder contribution. But when you rev it up they all go to 0 across the board. Was kind of thinking about the Variable Timing solenoid.

I have a 2005 F-150XLT with the Triton 5.4L. The other day while driving on side roads (Paved, not back roads) I noticed my CEL on and it was blinking. There was a very rough idle as well as a big loss of power. When I pressed the gas pedal it was sluggish to say the least. I have yet to get a computer on it, since I had to order one. There is also a light gas smell, only smells near the rear of the truck. From what I am guessing, I think it is either a spark plur or a coil over pack, Truck has about 56K on it.

I am posting about a cam sensor code and alternator belt squeal.
Yesterday after getting in from a 600 mile drive from salt lake to eastern Oregon i took a look at the car to put some fogs in and clean it up a bit. It had always had some odd vibration at idle and belt squeal intermittently at idle. I pressed down on the alternator at idle and the vibration noise went away. So bam. Found that.
The nut on the square head mounting bolt holding the alternator was missing. So it was kind of just flapping around. Replaced the bolt and put a lock nut on. Problem solved so I thought.
I'm still getting belt squeal. And i think that its out of alignment. It looks like the pulley side of the alternator is closer to the engine block than the other side. Is this adjustable? Is the bushing on the mounting side worn out to the point of movement? Is this fixable?
