This car has two o2 sensors one on the top of the exhaust, between the fan and on the headers. The other will be located under the car on the catylatic converter. If you have the right part it should be very simple. good luck

The sensors that you purchased were probably universal. These are normally much cheaper than OEM replacement parts. They should have came with wiring instructions and extra parts, you will have to re-wire the harness. If you were not given the parts to change the plug then you may have been given the wrong sensors. You should call the Auto Parts store and double check the Part number to ensure that it is right. Also it could be that the vehicle does not have heated O2 sensors, if this is the case than you need to get O2 sensors that are not heated to replace them.

Check for intake leaks, intake hose leaks, check mass air flow sensor.
02 sensors will keep setting off a lean code until the air problem is fixed.

Mazda 626 1999. The problem is that the car idle is 1250 rpm and I turn the a/c and run at 750rpm and has a misfire or at least start shaking bad .just on stoplight or stop sign other that runs good but...


the code refers to the Heated Oxygen Sensor (upstream) this would account for the high revs at idle as the fuel/air ratio is weak so the ecu is try to keep engine running ,you could try a fuel addative that is specifically designed for the catalytic converter as well as the valves etc as this will clear any carbon deposits that have built up on the sensor as well ,follow the manufacturer instructions on the product you choose

1990 Jeep Wrangler 2.5l idles rough/ black smoke/ fuel odor


You could pay a garage to diagnose the problem cheaper than throwing more parts at it.
The problems may be connected or they may be different issues.
Yes I would change the oil and filter, but first I would make sure the fuel system is not dumping too much fuel into the cylinders.
The O2 sensor helps the computer decide on how much fuel the engine needs, along with the other sensors. And you said you have already replaced the O2 sensor.
A mechanic would take a scanner and "read" the sensors and look for something out of normal range.
The fuel pump and fuel filter are off the list as far as causing a rich mixture goes.
I would start with the rich mixture and then see if fixing that issue takes care of the no start when hot issue.
Change the oil and filter first, and see if the injector is on too much.
You can watch the spray and tell - at idle it should be very light.
Also look at the engine temp - is it warming up to normal 195 degrees? Can you tell if the fuel pressure regulator is blown and pouring fuel into the throttle body ?
Without a scanner its going to be more difficult, but not impossible to diagnose.
Let me know what you find out.

yes it will. Also the EGR system may have a problem now too. When a o2 sensor goes bad it can destroy the egr valve and the map sensor too

I put gas in my 200 ford expedition and my service engine soon light came on and it started to drive funny.


It is possible that you left the gas cap too loose, but that shouldn't cause the driving funny thing. What do you mean funny? Did you fill it all the way up and then go even more? If so, you could have over filled it and gotten gas into the evaporative canister which is only supposed to pull air and may now be pulling gas as well causing it to run funny.
Hope this help. Good luck!

It surely sounds like you are confronted with a damaged cat converter. The o2 sensor is what triggers your ck eng ligh and it is located both up and downstream of the Converter. Won't hurt to have it chk'd. If there is a sulphur odor coming from the exhaust, The cat conv is bad. Good Luck, Ned

Failed O2 sensors? or fuel filter?


i would point to the actual fuel pump when they go weak they cannot supply enough fuel and it will miss and set o2 faults fuel filters usually cause a jerking under a load and will lose all power
