hi all...
my car has been acting strangly for the past few days... its a 2001 accent 1.5gls.
it just accelerates itself while driving... and when i step on the cluth and brakes at traffic lights, the engines simply keeps on reving... i've had it check by the hyundai machanics here but they couldn't find anything wrong. so please, if anyone of you guys have any ideas? thanks...

It's your battery it's dying and needs to be replaced. A dying battery can do strange things to you engine management system. I had a similar problem and no dealer found it until I let the battery go flat and the problem was solved.

thanks for the info johnc, it really appreciated. i'll go and try on a new battery. Hope that solves the problem... cos its really hard driving like this in heavly congested roads in nepal.

Before replacing the battery, have it tested. Alot of times a faulty TPS ( throttle position sensor) will also cause this. In order to properly diagnose the TPS you would have to graph it using a scan tool. Also check that the accelerator cable is not in a bind. Usually when a battery gets discharged you will have a hard time starting the vehicle.The easiest battery test to do without a tester is to turn the ignition key to the accesory position, turn on your headlights and turn your blower on high.Leave the key on for 5 minutes and then try starting your car. If a battery is defective the vehicle wil not start. It is best to perform a complete diagnosis before wasting money. :thumbsup:

hyundai tech is correct, the TPS is at fault.

thanks alot guys... i'll have the TPS checked first. but shouldn't the stored codes come out on the hi-scan if it was the TPS? but still, i'd better get it checked.
