if the o2 sennsor and the coolant sennsor is bad. how dose the car act?

 

Ok I changed the engine temp sensor pumped the tires up tp 44#and drove for 100 miles and it took just over 5gals to fill so thats 20 mpg.thatsa good improvment!! I just changed the o2 sensor and filled the tank when I get to 100 miles I'll fill again and post results

still no one has told me about the air pump,if i take the belt off what'll happen?

 

not sure i don't think anything much except it'll stink more...i changed my plugs, wires, dizzy cap/rotor, fuel filter, and cleaned the fuel pump screen and now i am getting 20mpg city with light spirited driving

 

Ive done that stuff too but for some reason i still only get around 6-8 mpg. but then again turbo cars were made to play with lol.

 

Great information! Thank you.

i am ready to buy the O'2 sensor and the New Coolant temp sensor just need to know what the part number is for the 1984 rx-7 1100cc (base model) manual transmission with drum brakes. if you can help let me know because at checkers they have a lot of different parts that pops up and well if i just had the right part number that would help alot. thank you much DR.

 

Ok I just did 124 miles filled her up the exact same way and it took 5.4 gal. thats almost 23 mpg That said it is warmer now {ie the temp sensor closes faster less air/cu.vol. etc] so by changing the air filter,o'2 sensor, engine temp sensor,cleaning the plugs,ful synthetic oil,pumped tire pressure up to 44#, new oil filter it went to a rough idel 15 mpg to smooth strong 23 mpg I'm happy....for now.....the cats are next to go and that F@#%ing air pump that mocks me like a smug look from Al Gore

 

witch engine temp sensor are you talking about the air intake or the coolant if coolant its the one on the neck? right now I am getting about 18 to 18.8 mpg depending on how hard I drive I got a cone filter no air pump and RB full SP exhoust on the car I have cleaned the gas tank and the lines out from all the crap also replaced the rotor cap and wires to 10.8mm with some new plugs I guess the o2 sersor is next.
