RX300 Problems Cat and brakes
 

Problem 1.

The car had some loss of power and bad idling problems, turns out the cats were blocked up soi removed them , How will this affect the car ? It still works crappy !!

Problem 2 .

After driving around for a few minutes i loose brakes !!!! What can be the cause of this ?
The brake fluid doesn't seem to be leaking and the fluid is clean .

1. As long as you are in a location that does not do emissions testing, then your other issues are loss of power at low end. In addition, you may be getting a check engine light, perhaps a P0420, without the cat. You need to let us know more about what exactly was removed. I won't get into legal issues with this, but there's no issue as long as you are somewhere without emissions testing.

2. Air in the brake lines can cause this issue. Feels nice at first and then you have to literally push the brake pedal to the floor. It's generally a two person job to flush the air out of the brakes (can be done by one person either carefully and/or with the right equipment), but if you are getting an issue that bad, I'd left a professional do it and be done with it quickly.

How do you know the cat was blocked? You removed it and it didnt fix your driveability? As far as brakes go... you need to provide actual details before anyone can even try to diagnois over the net. " loosing your brakes" provides no useful info.

I live in the Caribbean so no emission testing. I pulled the CAT to check it thats how i know its blocked. I get no CEL . I have installed 3 brand new o2 sensors. The car works good sometimes and sometimes like ***** .

I will bleed the brakes tomorrow and see if that helps.

I will drive the car tomorrow and write down everything that occurs to best explain myself.
