O2 sensor problem

[sky_cz]

So, look i ll be long out of road and spring is comming. I ve slowly and hard reach my garage.

No idea what coud it be, starting car is normal, rpm is ok, all temp raising normal. When i pull gas, car getting nonstardat vibration and no power, resp very small power for full gas, i feel light pause and "power jump" after i pull gas pedal, from exhaust grey smoke, and as last i take notice that cat is completly red, exhoust is very very noisy, but abnormal sound.

sounds like your ignition has issues and the gas is not getting burned . . . ending up in your cat . . . ignition module or intake sensor . . .

can ve conjuction with engine wash?

Do you have access to freescan you can provide some data.? Which model esprit do you have?

Do you het any error on the dash?

Strong possibility it's from washing your engine... dry up the coil packs... clean out the spark plug area of water... and go from there.

I have seen many an engine wash with engine cleaner kill or destroy a throttle position sensor . . .

Do you still have the EBPV in the exhaust system ? If yes check that is in the open position and not stuck in the closed position. This valve was originally installed in order for the CAT to heat up in shorter time due to emission regulations. They are prone to failure and on a lot of cars they are disabled / removed. If you don't have the valve then maybe your exhaust is (partially) blocked. These things are easy to check.

disconnect the vacuum line to the valve and make sure the valve is open... then plug off the vacuum line with a bolt.

so after my todays research no EBPV there, so i ve started, and everything ok, normal reaction of gas pedal, correct sound and smoke from exhaust, moving back and front by car no problem, gas normal reaction.

i ve discovered some blow in cat and exhaust connection, but nothing big , but thats not this problem

my enthusiasm was very early:(

after 2-3 mins recognising vibration, changing sound of engine, exhaust, and again feeling after pulling gas pedal little delay, and cars moves very clumsily and infirmitly, like yesterday.

Chances are you have either an ignition failure or an injector failure. First you need to find which cylinder(s) are not working. Pull each plug lead off, one at a time -- if the idle doesn't change, that is your bad cylinder. Do the same with the injector plugs.

not a nice view for everyone

Hi,

I personally would bet that it is a faulty O2-sensor. If the problem comes on after a couple minutes, than it is very likely a faulty O2-sensor.

The first minutes after startup, the engine runs on fixed tables in so called open loop mode, then when it got warm a little bit it will switch to closed loop and will do all the fuelling via O2-sensor input. If the O2-sensor is faulty and gives faulty data, its very likely that it starts to get out of control either to the rich or to the lean side ....

Cheers

1 point goes to Germany................it was O2 sensor

[sky_cz]

ok cat has gone, so its replaced only by tube, sound like hell on earth, people running away and cars alarms starting whistle:)))

but my question is is not some bad impact on engine? or its good to ve cat there?

I had a problem that sound just like yours, turned out to be a bad fuel injector. get a noid tester at your local auto parts. then next time the problem occurs start unpluging the injectors and see which bad . jp

Great to hear that !!!! B)
