cat. converter???

[silver cobra]

Alright, I posted about a month ago about my 1995 Toyota 4Runner having problems. The rpms would go up but I would go the same speed. I had several people tell me it was the transmission. Well, I had the transmission fluid changed and that seemed to work. Now, about 3 weeks later, it is doing it again. I couldn't get above 40 mph while trying to get on the interstate. My dad says that it maybe the cat. converter. If it was the transmission I would think it would do it all the time. It only does it sometimes and then stops for a while. Is it possilbe for the cat. converter to be stopped or plugged up for a time, then break loose later and give me my power back? Also, I can smell a kind of sulfer smell coming from my car. If there is anything else it might be just tell me please. Thanks for any help.

I think you misquoted your dad. Torque Convertor.

I have seen trucks/cars with the CAT plugged.. The bad thing is if you run it too long you can start a fire. The best idea would be to hit the same RPM's that you do when the problem occurs, but in a lower gear. That might help to determine if this is an exhaust or tranny problem. You might also get a volunteer to help rev the car in park while you put your hand over the exhaust outlet (don't touch the muffler or the cat). You don't get an increase in pressure out the back, you have an exhaust problem. Troubleshoot one system at a time as best as you can to isolate the issue.

You guys are all taking stabs in the dark. Read the symptoms. This is clearly driveline related and not fuel filter, plugged cat...etc.

The problem exists in the driveline, most likely the transmission.

Very well could be the torque converter but have not heard of it going up on the 4Runner though.

Alright, I understand what you guys are saying and I will try to test it but why does it not do it all the time. It has done it in hot weather and also in cool, rainy weather, so I know it is not temperature based. It has done it at low speeds and also while I was trying to reach high speeds. I had a transmission flush and it ran fine for about three weeks. If it is transmission problems shouldn't it do it all the time. On average it does it maybe once a week (considering I drive to school or work everyday). Thanks for all the help so far, just if someone could answer this last question.
