help!!!

ok heres the story. i bought a 2001 hyundai accent 2 weeks ago its a 1.6 dual overhead auto. i knew there where problems w/ it but im willing to fix if i can figure out whats causing them.

the person i bought the car from drove the car to the garage after the timing belt snaped. after the new belt was put on the car sputters and stalls out. the only way to drive it is to drive with both feet. one constantly being on the gas. the engine is miss firing real bad. i have replaced the spark plugs, timing belt, wires, throttle position sencer. im out of options and i dont want to get rid of the car. some one please send me any ideas on what it might be. its driving me insane

 

More than likely, you've got bent valves that occurred when the timing
belt broke. You may also have damaged pistons.

Yuk - hope you bought it real, real cheap

timing belt snaped.

No they didn't. You don't drive cars with broken timing belts. Think about
it...

Why would you have changed all of those things? You have to quit throwing
parts at this car or you'll have a brand new car on your hands that still
doesn't run. Since it broke the timing belt, it's quite likely to have
valve train and possibly piston damage. Even if you miraculously escaped
those with a broken belt, it sounds like who ever installed the new belt
might not have properly timed the cam to the crank. You've got a lot more
to look at (and I suspect a *lot* bigger problems) than plugs, wires and
sensors. Get the pocket book ready...

If this car really did break the timing belt as you believe, then I have to
question the line about it going to a garage. No mechanic in their right
mind would put a timing belt on an interference engine and send it out the
door. Hell - no mechanic would put a timing belt or chain on any engine
without tuning and testing. This sounds like something that was done in
someone's garage - someone who had tools enough to be dangerous and not
enough knowledge to be doing this kind of work. Hate to say it, but I think
you got hooked.

 

Mostly likely bent valves and possibly damaged pistons and connecting
rods. Best case would be mistimed cam when the new belt was installed.
You almost certainly need to have the engine torn down and overhauled.

how is that possible, the engine would not be running if the timing belt
snapped..
sounds like your have some busted valves etc from the timing belt snap.
youll need to get your head looked at at a hyun dealer ....

 

Instead of randomly buying parts, spend $5 for compression gage. If you have
1 or more very low cylinders, there is probably damage from the broken
timing belt. Valves get bent or chipped, piston crown broken, rings
broken... not a pretty picture.

 

Unfortunately, Mike, I've seen cars where mechanics have done just that--
replaced the timing belt, buttoned it all up, and sent the customer back
out, all with the car running like crap. There are too many places out
there that call themselves repair facilities when their employees have
just enough tools and knowledge to get themselves into trouble.

As for the misfiring being caused by a mistimed belt-- no. It'll cause
the engine to lack power or even to run very poorly, but won't cause a
misfire-- it'll affect all cylinders equally. Of course, based on the
o.p.'s post, I'm not all that sure it's actually misfiring, either.
