2001 Accent
 

Hi there everyone. I am new here.
My check engine light came on about two months ago. Had it checked, said I needed a front O2 Sensor. I didn't have the money to fix it and I was told that I didn't need to fix it right away. Well, I just now have the money to fix it.
Anyway, I have noticed that when it was cold out, and I started driving, it was acting funny. I would drive about two blocks and even though I had my foot on the gas, it would feel like I was hitting the brake. It would slow, kindof like I was down shifting. I would take my foot off the gas for a second and continue driving. After about 10 minutes of driving it would be fine. But today, it was doing the same thing but longer. I was fine if I was on the interstate, but once I got off and I had to slow down or stop, it kindof jerk. But its really noticable.

A couple of weeks before I found out about the O2 sensor, the check engine light came on and I needed new spark plugs. It was driving the same way that it is now. Its weird because the engine light will come on for about a week, then off for a week. Now it is off.

Could my problems be happening because I need the O2 sensor? I am trying to get it fixed today(Friday or Sat.) I am just worried that I will fix that but something more serious will be wrong. Any ideas?

The 02 sensor will cause those problems. A simple fix though, have it replaced. Tossing in new plugs and a simple air filter wouldn't hurt either. Then for good measure, throw in a bottle fuel treatment, (I use Marvel Mystery Oil...4oz per 10gal) and fill up with super.
Lets us know how you made out!!

Good suggestion Brant. I would tend to agree that the 02 sensor is a possibility.

I have an appt. on Monday morning to get the O2 sensor changed. I just put new plugs in a few months ago. A week after I did that, the engine light came on again. Thats when I found out I needed an O2 sensor. When you say fuel treatment, do you mean like a fuel injector cleaner or something else? I'll fill up with super after I get it fixed. I have just over a quarter tank right now so I should be able to make it last until monday morning. If I need to get gas before, can I mix the super with the ethanol?

A fuel injector cleaner will work.

Might I suggest STP injector cleaner. It works pretty well.

RE: 2001 Accent
 

Thats sounds good. I have to a pretty empty tank to put that in don't I? I put it in when I fill up, right?

It's getting fixed in the morning. I just really hope it works and my car doesn't drive like it is now.
Thanks!

RE: 2001 Accent
 

Glad things are working out for you. Your tank should be empty and them put the cleaner in and filler up.

Please don't forget to let us know how you made out.

Hi everyone. On Monday, i had the O2 sensor replaced. I told the mechanic the problems I was having. He said he would replace the part and take it for a drive. He took it for a 10 min. drive. He came back and said he thinks my transmission was going. Here's what it's doing.
When I start the car, no problems. When I shift into drive, no problems. When I drive down the road, no problems until I get between 20-30 mph. At this time, its struggling to get to 30. The rpms don't go past 3. It starts to jerk so I take my foot off the gas and it slows way down, jerks, and driving normal again, until I press the gas. It does this until I can get past 30 mhr. It is when I do in town driving, stop and go. I take the interstated to work. When I am taking the on ramp, it jerks. Once I get on the interstate, I have no problems getting from 30 to 65. I don't have any problems driving, until I have to get off the interstate and slow down. This problem has been going on just for a couple of weeks, it came out of no where.
So, in the past three months, I have had new sparks, plugs, and a front O2 sensor. The car is a 2001 Accent, 1.6, with just over 95,700 miles. I haven't had ANY problems except in the last three months. The other day, we looked at the transmission fluid, it was darker then it shoud be( I have never had it changed or anything.), and he did notice very small fragments. My boyfriends friend, who is certified in transmissions, took it for a drive. He was doing the shifting manually and was having no problems at all.
I also called Hyundai to find out about my warranty. I was lied to about it. I was told that I had the 10 yr/100,000. I don't because I was not the original driver. This makes me very mad because the only other person to drive it, was a hyundai person and it had not been "sold" to anyone but me. If we didn't get the new warranty, we would have bought a brand new one. That was the main reason we bought the Hyundai.

I did some researching. At least as much as i could do with my little knowledge of cars. I found some info about a pulse generetor or a transmission-fluid temp. sensor. Any ideas?? I am taking it to another place tomorrow for an ispection. I'd take any ideas anyone has to offer.
