Catalytic Coverter

#1 Post by cdsw00 » Thu Mar 17, 2011 4:58 pm

Hi,
my Rover 214 SEi 1995 has been giving me problems, stalling when moving off, cutting out at traffic lights and a general loss of revs when changing gear. I have had the Lambna Sensor, the Crank Shaft sensor and the engine coolant temp sensor changed and it made no difference. I have just had the Fuel Filter changed and the Catalytic Converter checked, the cat converter was full of water, the guy emptied the cat converter, now the car is running a hundred times better, do you think that the cat being full of water was the cause of all my problems?

could be, but if it is full of water, you may want to check your water levels, and oil cap for mayonaise. as water may be leaking through the head. meaning head gasket problems. if the checks are fine, then the head may well be fine, but it is worth keeping a close eye on it.

I have checked the Oil Cap and the oil is nice and clean no Mayonaise. I will keep a close eye on it though.

if its a recent buy for you... it might be that previous owners had gasket problems and changed it..... or else in past life car was involved in alot of water.....

The only way water can get into the cat is from someone filling the exhaust with water via a flood etc, or a severe coolant leak.

One good drive and the cat should get to several hundred degrees C, so all the water would rapidly boil off.

Thanks for your advice, I have had this problem since the deep snow we had, my Rover didn`t get used for 3-4 weeks as it was up to the Bonnet in snow during that time.
I gave it a good fast, long run up the Motorway and it seems to have helped.
