Pls i need to know where is transmision oil filter and fuel filter to change them car don,t run more than 30 miles, i,ve changed speed out sensor thanks in advance

How many miles on it? Is it idling at the proper speed?Is it due for an oil and FILTER change?
Could be losing oil pressure. are you running the factory recommended weight of oil?
If you're running 5W-20 then change it to 5W30. If you are running 5W30, then go to 10W40.
In other words,when the oil pump gets worn or the crank and cam beareings develop more clearance with age,you need thicker oil.
If the oil is new and you don't want to change it,add a bottle of regular STP oil treatment. This will increase the viscosity. don-ohio

change oil,use 10 w 30,use better gas 91 octane at least,the sensor is not bad,it is telling you there is a knock,stop sweating the small stuff

You need change oil and filter the transmision need right now and clean up the throttle body and check the IAC and TPS and any vacuum leak.

drop the transmission oil pan and drain it and replace the filter...
If you have over 100,000 miles and have never had a transmission flush before, don't do one now. just do a drain and fill. if that doesn't help, you might need a rebuild.

I’m happy to help further over the phone at https://www.6ya.com/expert/jason_00b31cc8f593773a

could be a lead or plug breaking down which are the most obvious when under load ,but please explain why the transmission oil changed ?? i was always taught that auto boxes are for old women and the oil in them never needs changing .I have never seen this on any workshop manuals for the need to change the gearbox oil on a auto.

check oil sensor it is probably coincedence that you fueled at the same time

most likely suspect is the carb

However, I'd start with your basic tune-up first...

• replace spark plugs
• replace spark plug wires
• replace Dist cap and rotor
• replace fuel filter
• replace air filter
• change oil
  
• adjust timing and base idle speed
• adjust fuel mixture (if available)

Cheers

Black some is from too much fuel, blue smoke is from burning oil. Keep an eye on oil consumption now. If your check engine light doesn't come on, just keep an eye on it. 20k miles??? Dude!

Change oil every 3000 miles. Use 5w-30 weight.I would use syntetic oil base. I found on mine it runs quiter and smoother, better for the car also in the long run Buy it at a local auto part store..do not go crazy on the brands if you will change oil every 3k miles. If you want to go longer get the Mobil-1 syntetic for the 15k miles..but do it yourself..you will save tons. Every 12k miles change the air filter, very easy. Undo the clips , there are four of them and pull out the old and place the new one..five minutes operation ( $12.00) you can do the oil yourself also..10 minutes ( $13 ) . Spark plugs and rotor and distributor cap change every 30k miles, along with the fuel filter. Every 60k , I would change the spark plug wires ( 85 dollars) seems expensive , but you will definetly see a big difference in starting up the car,idle speed and performance as a whole....worth every penny.Timing belt change every 60k miles..do not take a chance on this one...it could be expensive if it breaks...not expensive (30 dollar part) and relatively easy..but have a mechanic or someone you trust. While you are there change the other belt, power steering and alternator belt( i think ) .You do this the car will drive for 200k miles without any problems

its about air filter ,

open your filter air & oil both than clean your air filter than try to change your engine or transmision oils also,

black smoke indicates that your engine can't get more fresh air for serial or parellel combustions,

its easy to solve.

try itwith care.no risk is there
