Hi, this sounds more like a blown head gasket then a O2 sensor problem. Check to make sure you have coolant. Good luck

My 97 Cadillac deville won't start could that be that my oxygen censor's are not good???


Even a bad oxygen sensor couldn't keep the car from starting. It has probably lost spark or fuel to the engine. Listen for the fuel pump "whir" for 2 seconds with the key in on position, not start. Or have the fuel pressure checked, and scan for possible trouble codes. That is the place to start: scan, fuel pressure, check for spark.

The engine light on my 96 merc cougar XR7 is on. Car shakes bad when i accelerate and engine light begins to blink. I'm embaressed to say my engine light has been on for sometime but was told it c


The check engine light needs to be addressed. Yes it could be a sensor but you need to know.
The light blinking means the problem is serious, such as a dead miss on one or more cylinders. The light being on means something is happening with the engine performance that could damage the catalytic converter.
Get the computer scanned - most auto parts stores will do it for free in hopes of selling you some parts. Once you have the codes research them online or here.

Changed oxygen censor, new plug and wires, new coils, cleaned the egr valve nothing worked still kinda revs up and slows down and stalls occasional haven't tried the sledge hammer yet


Fuel pressure regulator can do this. Also bad fuel pump could. Is it getting good pressure out tailpipe? Maybe plugged catylitic converter?

Just had diagnostic check as engine light is on. Summary is heated oxygen sensor - bank 2 sensor 1, emission system incorrect purge flow, and two emission system - vent control valve circuit. What does...


G'day mate well lets start with the O2 (oxygen )censor , it is in the exhaust and does clog up give a spiked reading ( on a graph or multimeter ) instead of a smooth transition like a wave flowing,this will tell all the other censors that the fuel flow/mixture/quality is bad , the rest try to compensate by raising the mixture changing timming etc, get the O2 censor done 1st then go from there, it should calm down once this is done,

Engine problem i think?


when a oxygen sensor is bad it shows and acts as if there is problem somewhere in the car. even though you had the O2 censor changed there is still a chance that when they ordered and installed it that it was defected. yeah its stupid but that was what i was told by a mechanic. but thats what that sounds like or maybe transmission.

Cranks but wont turn over


you know. i took it to a mechanic and actually.... The timing belt cut the Crank Shaft Censor... So it was the crank shaft censor again. The wires were routed wrong from the first mechanic that "fixed" the car.
