i have an 89 gtu, my friend has an 86, it smells like my car is running richer than his, he has no cats, my car has the orginal main cat. We both have headers. How can i correct this problem? My car also fails emmision test's horribly. I dont think its just me but these rotary's get some bad gas mileage.

You should be getting a little more than 20 MPG average on a NA. It almost sounds like your injectors are stuck open. Have you tried running injector cleaner through it?

yes i have ran injector cleaner through it 2 times, by stuck open do you mean even when the car is shut off? Because it never floods. I should really get them professionally cleaned but have no time to.

Yes, they would be stuck when the car is not running. Big problem on RX7s. Has your car alwyas done this, like since you bought it, or just recently?

From what i remember it has always done this, When i first bought it i thought that was just the way they ran. Another thing is when i had hollowed cat's on it i would backfire like it was going out of style https://www.nopistons.com/forums/pub...1047683785.gif , But my friends 86 has hollowed cat's and his never back fires https://www.nopistons.com/forums/pub...1047683561.gif , and that also lead me into thinking that my car was running richer than normal. But if the injectors were stuck open or "leaky", wouldent the car flood when you turn if off and try restarting it?

Yes it would. You may have upgraded injectors in it then since it has alwyas been like this.

The afm on my s5 was shot and ran really rich as well, it wouldn't hurt to check that out too.

Thats true. A number of sensors will make the car run rich.

How can you test the meter? Would it throw a code if it was bad?

Yes it would throw a code.

leave it rich, you dump bigger flames that way:D

Youngbecker, Id rather not blow $$$$ than blow flames, i used to think that was cool but the way gas prices are nowadays its not worth it. Plus with the stock cat in place its kinda hard to blow flames, when i had the hollowed ones thats all the car did.

check the temp sensor in the radiator also . ( it should be closed when is warm)

Dave

You say you have a cat, if it's clogged thats also a souce of bad milage.

bad o2 sensor will also cause poor mileage

Using the gas pedal will give bad mileage too.

A little re-cap:



Dirty injectors, bad afm, bad O2 sensor, bad temp sensor(s) and a heavy right foot



all contribute to bad mileage or making the car run rich, what are we leaving out?

The fact that its an rx7. I think it is just a fact of life that your car is going to run rich at some point in its life. Its just a rotor thing.
