Hello, I have a problem with my renata clio 3 (1.2) 16V 75HP the engine runs unevenly in every gear and in every speed range and the error is displayed CHECK EXHAUST SYSTEM. The car has 180 thousand mileage and gas driven 165 thousand Some time ago the valves and head planning were changed and...

Keywords on a well-known auction site - Catalyst emulator (second lambda probe) or

What errors were read from the engine controller?

From the computer the error of falling out of the cylinder was read and therefore the coil was replaced but it did not give the possibility of a catalyst but I do not intend to buy a new one and if I would like to remove it, the lambda probe will go crazy again.

Thanks, I haven't heard that much yet. And how can I be sure that it will help, because 150 zlotys is no longer on foot, I drowned on the coil 200 which did nothing, can there be any solution to this problem?

I have mounted the same in Scenic and it has been working flawlessly for a year and a half but since the executioner is clogged, you still have to cut it.

Thank you very much for the advice, I hope it helps because I can't ride anymore. Any day I will be working with the topic ? kisses.

How much after that done on gas? Ignition loss is the norm with gas not properly tuned in this engine.

Candles replaced Ignition cables replaced? Valve clearances adjusted?

I have done about 13,000 on gas since the engine overhaul. And everything was ok and now I drive only on gasoline because I dismantled LPG because I don't do as many km as I used to, besides, I had engine repairs using gas. And the candles and cables were replaced

Not by gas only because of the grandfather's installation, printer's assembly or both.

Hello, I have a problem with my renata clio 3 (1.2) 16V 75HP the engine runs unevenly in every gear and in every speed range and the error is displayed CHECK EXHAUST SYSTEM. The car has 180 thousand mileage and gas driven 165 thousand Some time ago the valves and head planning were changed and something else but I don't remember anymore. The coil was replaced but it did nothing. My mechanic no longer knows what the possibilities are, but it is not known what this is, please help.

Hello.
I just worked on such a problem with uneven operation of the engine on a cold. One mechanic dismantled all engine equipment and electronics including the computer. The effect my car was the king of tow trucks for several days. I set the ultimatum cart to be brought to the state at least from the first visit to him. I changed the mechanic and surprisingly managed to heal 1.2 16V. The previous "magician" adjusted the valves too tightly.

Hello
I used to have such a problem. Uneven engine operation, CHEK indicator lights up. Adjusting the valve clearances helped. I warn you, not every mechanic can do this. Renault are specific cars
