What would cause a backfire? Just curious cause my DD spat a few out today, BTW its a toyota tercel (95). Just curious as to your thoughts on the causes

 

Raw fuel contacting your exhaust and exploding. ( correct me if im wrong).

ur correct. if you are running rich as hell, it will do that.

 

yeah, happens to me many many times a day. the real question is, can you shoot a fireball?

I can shoot a fireball, but only if I get two purple upgrades and one of the blue flashing ones..

hmm... do you mean accidentally or do you want to shoot a fireball?
I've heard of a few exhausts that can let that kind of thing happen, but no idea if it's doable in a tercel (not ripping on toyos, just don't know much about them) but i think that involves a race cat or test pipe and a bit of luck.

if you want to shoot fireballs (sigh) look on ebay, there are kits you can get.. they're "for show purposes" only, but basically it cuts out your spark for a second so there's a lot of fuel in the exhaust, then there's a spark plug at the end of your exhaust pipe, so it burns the fuel...

 

no, didn't mean a kit. my exhaust does that from time to time naturally, although I can do it on command. Yes my car runs that rich.

 

you must get great mileage

 

my car was running rich when i had CEL and a gutted and i would just drive it hard and swich from 1st to 2nd and boom! my friend that was behind me said it was like a matches but not a fire ball and the car always smelled like gas

 

my mileage is bad. my car doesn't smell like gas though. it's not bad at all until higher rpm's. you don't want to be behind me when I get on it though, i leave a small cloud of fuel and other misc **** in the air behind me, and yeah i get backfires between every shift.

 

This is just on a stock crappy tercel.....i was just wondering if i maybe need to adjust my valves or something

 

ur also getting less horsepower.

 

Get it tuned?

Check your O2 sensor...it could be screwed up.

 

i'm thinking I need a fpr first, then a wideband (instead of stock replacement), then a chip burner.

what does mean when ur running rich? good thing? i'm noob

 

first off, thank you for using the search function


running rich means there are more parts fuel than air inside the combustion chamber than normal/necessary. Its not a good thing, but its not bad unless you are running insanely rich. Running too rich can be VERY bad and can ruin the motor. By running a motor too rich, you can wash the oil off the cylinder walls and the rings will eat up the cylinder walls and in the end you will loose compression.
