Replying to: killroy (Mar 29, 2000 7:29 pm) I own a mazda mx6. Recently i was told that my catalytic converter was blocked. My car has not been shifting gears and going very sluggish like at times i cannot get it to go above 20 mph. I was wondering if there was a quick fix to this because im about to trade my car for a honda prelude and i have to get it to the guy because we are trading cars. He is aware of the problem but at the moment i just dont think my car will make it there. IF you could let me know if there is any way i can make my car work for a short period of time that would be great. thankyou.

Replying to: latino20782 (Sep 20, 2007 5:36 pm) One issue common to these cars is clogging of the EGR passages in the intake manifold and engine block with carbon. This results in engine light coming on, sometimes intermittently. The code is I believe P400 (insufficient EGR flow). The way to fix this issue is to remove the throttle body and spray carb cleaner into two passages on the bottom of the intake manifold just past the throttle body. These are EGR passages. They run through the manifold and the engine block all the way to the EGR valve. Replacing the EGR valve will not fix this problem! It is an electric valve and very expensive - about $ 350, even from aftermarket sources. So do not replace it unless you are absolutely sure it needs to be replaced. But first find out what the trouble code is in your case. At 92k miles you should: replace the timing belt if it has not been done already (recommended at 60k), including all three tensioner pulleys. Auto Zone sells a nice timing belt kit that includes the timing belt and all three pulleys for something like $ 100. Do not even try to price these from Mazda, as it will be about $ 700! And bearings wear out in these pulleys believe me! I replaced mine at 105K miles. Also, check the tensioner pulleys on the engine drive belts. The pulley bearings tend to go bad. You can buy replacement bearings, but you need a hydraulic press to pres them in and it is a tricky process. New pulleys are expensive - almost $ 100 a piece. Even aftermarket ones are expensive. You should think about replacing the plug wires if it has not been done already. What about brakes? Are pads in good shape? Check the outer CV joint boots. They often start splitting around 90-100k miles. You may want to change the water pump if you do the timing belt. Be warned - changing the timing belt on this car is not easy! I have done it myself so I know. You need to remove the front engine mount to install a new belt and to replace the water pump. I do not recommend this job to anybody without sufficient experience. You are best off finding a good mechanic to do this. There is a lot of pitfalls associated with this job. |
