I was looking at the Chilton’s online that we have a link to in the ‘How To’ section and there is an exhaust gas sensor used on that vehicle.
It also shows trouble shooting procedures too.
No, it is not the ho2 sensor. A ho2 sensor is a 4 wire oxygen sensor.
The exhaust gas sensor should be by the exhaust manifold. The picture of the sensor and its location is shown in the Chilton’s library for your vehicle.
I don’t think any of those codes would be responsible for an idle fluctuation, for that I would recommend looking for vacuum leaks first thing, that said I wouldn’t worry about the O2 sensor till you address any potential vacuum leaks as that could help set the code for the O2. As for the crank sensor I’d recommend at least checking it’s resistance or better yet perform the check in the Chilton manual before you buy a new one, it’s also a good idea to do a good visual inspection on the wiring and connector as well.
ok guys i know its been awhile but finally found something that sounds exactly like my car, and here it is…
@erick all of my vacuum hoses are new i replaced all of them the more i look at my car the more i get frustated, my car was working turning on but i took out my crank sensor well the whole distributor cause is under it and cleaned it now the damn thing wont turn on it just sounds like the video above….ok erick will do i will do it tomorrow, i had spoken to 2 mechanics that wer suppose to come and look at it everyone seems to be scared of my car lol.
really is my car that complicated so mechanics are that scared???????Where are you finding these ‘traveling mechanics’? If it’s on craigslist or something, I wouldn’t get yer hopes up too high.
If you suddenly don’t have compression it may be that the engine is flooded, pull the plugs and check if they’re wet, if they are dry them out and let the cylinders air out then when you go to crank after everything is dry hold your foot to the floor on the accelerator so that you can ‘clear the flood’ and get compression back. I know you say that your hoses are good but that’s not the only possible source of a vacuum leak, it could just as easily be the carburetor base gasket or intake gasket, heck it could even be a worn out throttle shaft but you have to check for them using the method in the video link I gave you or some other method but a visual inspection just isn’t going to cut it.
if the car sounds like the video do a compression test. I still think the car has a timing issue. I would remove the timing cover to check the timing
marks.it is indeed a lil not much but timing belt looks to be near its end i will change it tomorrow as i have to change the brake kit on my car and its easy to get to when the tire its not on the car thanks fellas once again mechanics dont seem to want to make some money so i will do it my self i spended more time waiting for mechanics to come through then anything else and nothing thanks alot guys
when you replace the belt be sure to line up the timing marks. do you have a service manual? if your taking on these jobs a service manual is
your best friend here. C8-) heres a link from our forum. I know it goes to 1994 and you have a 1987 might be helpful go to the maximao no if i take my passenger tire off its easy to access the timing pulley, so i think it wouldnt be much of a hassle but then it might get complicated.
thanks college men i was looking at the app you sent me i dont see 1987 maximas on there only 1994 and up, i am not sure its the same deal i think the manual goes from 1985 to 1989 if im not mistaken….is there anything to put on my throttle body gasket i have a really good hunch it might be leaking from in between the gasket and where the the 2 parts meet the throttle body and the block that is… any tips on what to use??????
ok so i took the spark plugs off all 6 like i said before got them new about 2 weeks ago, turns out when i pulled them out they’re burned smelled a bit like gas all of them wer black at the tip all of them.
just to be on the safe side i took my manifold off and the gasket was broken in 3 pieces, i do not know how it happen since i got it brand spanking new.
i will replace the gasket,change the timing belt,readjust the timing pulley and from there on i will post again to let you guys know how that turned out.
