today, i got up and I go with my bother to left his car in a car shop. and when we tried to go to his work, my car started to fail..

It was like drowned... i tried to give a lot of gas and my car was like he wants to acelerate but nothing happen. and after a little while was ok. but after it got worse, it doesnt want to accelerate and when I press the pedal my car wants to but its like he is drowning. 02.gif

anyone knows what could be happening?

I already checked the spark plugs and they´re fine, my battery is fine too.

could be spark plugs wires? or gas filter?

thanks

 

Do you drive an auto or a manual? If it's a manual, you need a new clutch. Really bad.

 

The only time you would need a new clutch with something like this is if when you push the gas down all the way while in gear the rpms fly up. Is your air filter ok? How about the PCV valve? Have you done anything to the car before this started happening?

It helps if you talk in full sentences.

 

what mods do you have?

Check your wires. Look for any breakage in the boots. How many miles has it been since you last changed your wires? I recommend it at least every 30k miles.

Check your air filter, that sucker could be pretty clogged up.

Auto or Manual? Please list mods, if any.

 

ok thanks.. sorry about that. i´m kinda upset, I have a auto tiburon, and I didnt do anything before this thing.

I have K&N filter, and I tried without the filter to see if its for the filter but no.. it was the same.

when I press the gas pedal to the floor, instead rev up, start to rev down untill ithe engine turn off.

My spark plugs wires has 60800 miles, my plugs has only like 100 miles.

My gas filter has the same as the wires. and I dont know where the PVC is located.

Your K&N filter could have messed up the MAF sensor. Oil got all over it.

Also try to replace fuel filter, and check fuel pump.

 

Are you having trouble starting the car? If so check your alternator too man. When mine went it did the exact same thing, sputtering to a stall, and then not starting.

I dunno, seems like there is a blockage somewhere.

 

The PCV valve is on the back of the valve cover. It supplies o2 to the valve cover. Not saying it is causing this exact problem but you usually change them when you do a full tune up. I agree with op. Is your MAF sensor (the tublar thing in your intake path) pointing the right direction? It has an arrow showing which way the air is supose to flow.

BTW I wasnt trying to come down on ya just saying it was pretty hard to make out what you ment in your first post thats all laugh.gif

 

Ok thanks and dont worry man, Thanks for the help, I check my alternator and its fine, my battery is fine too. My o2 sensor is recently changed for a new Bosch one.

My MAF is in the right direction, since the last saturday when was the first time my car did this, ( fo r a little while then it was working normal ), te last thing a did was replaced the O2 sensor it was an OEM first o2 sensor.

and today was the sencond time my car did this like I said since last saturday, and I dont know why. I didnt do anything, just replaced the sensor, and the most weird was that the saturday did this and since then untill today was today again.

BTW my car start normally.

I just start the engine after check the plugs and it was working fine, but i will drive it till this afternoon to see if does that thing again.

I will buy the fuel filter anyways and try to buy the bosch plugs wires too. the only thing bad its that where I can buy the wires aren´t available right now. so I will have to buy the stock ones or wait to buy that ones.

thanks again.

 

There is a GB going on for some nice plug wires for less than you would probably pay for stock ones. You might want to check that out. Let us know if the fuel filter and such helps.
