running rich!

[high c]

i just put 300cc injectors into my 90 camry with a 3sfe. every thing working roght no fuel leaks and all the wiring is the same but my car is running so rich, rich enough to stall it when i give it some gas to try to speed up. is there anything i can do to lean it out? i put the 300cc injectors in because i am puting a turbo on soon so i will need more gas. anything ideas you can give me will help alot thanks

put your stock injectors back in till you put the turbo in

in theory they should still work fine, maybe they`re just hooked up wrong

get an safc or something- you'll need it later on anyway

is there a way to re-set the ecu, could be the problom? i really dont want to take the 300cc out because to do that (easy) you need to remove the intake manafold and that sucks

The problem is the injectors.

You have no need for 300cc injectors on a n/a 3S-FE.

You don't need to unbolt the intake manifold. Just unbolt the fuel rail and move it out of the way.

i thought that running bigger injectors even when it's not necessary was still ok...it just meant that they'd run at a lower duty cycle

Bigger fuel injectors are for allowing more fuel in... The only time you allow more fuel in is when there's more air flowing into the system... thus enters the Forced Induction issue. Stock injectors are fine till you put the turbo in as others have said. There's no reason to be running 300cc without added air.

ok, i put the old (200cc) injectors back in and now the car wount start, it cranks fine and theres fuel in the fuel rail but it dosent start no matter how much i crank, any ideas?

did you fuck with anythign else?

if not, then bring it to a garage and pay a stupid amount for a diagnostic since you did stupid shit

^^ What he said.

Did you hook everything backup properly?

ummm...what sense is there in adding so much extra fuel to ur mixture if there's no extra air added to burn with it? *sigh*

reset ECU...try again...THEN bring it to a garage and pay a stupid amount for a diagnostic since you did stupid shit

i still don't get it...some of you guys are making it seem as if just because he has bigger injectors that he is automatically receiving more fuel...i don't see why the motor wouldn't put in the same amount of fuel as before since the amount of air coming in hasn't changed...

i think the injectors would run at a lower duty cycle, which is a little better but it's not absolultely necessary...

i think he just installed them wrong or maybe some sensor is screwed...i don't think it is the 300cc injectors alone that is making him run rich

[high c]

how do you reset the ecu?

[Hook]

disconnect battery...chill a bit...reconnect it...drive around a bit to re-program it to ur driving habits

this makes more sence to me, shouldnt the computer select how much fuel sprays according to the amount of air coming in???
