code 25

[python]

i have a slight misfire on my 92 LS 400, i have tuned it up using dealer parts, i believe one of my injectors is failing, code 25 is coming up, and yes i have changed both 02 sensors before the cat, my question is, will an injector misfire cause this code? also i am about to put some 251 injectors in from a 93 sc400, from what ive read i should be ok with this ....any input would be greatly appreciated, i have seen posts from you guys and i know you have a lot of knowledge.....thank you

Here are the Error Codes http://www.lextreme.com/Lex DxCode.pdf I dont think installing larger injectors going to solve your problem.

 

[python]

changiging injectors or replacing them with known good ones will fix my misfire......when i put in redline fuel system cleaner the misfire goes away

 

[sideshow]

u cannot change injector size without remappin the air flow signal

u need to fit exactly same flow injectors as what u get out

 

[python]

well ive heard people have changes injector sizes and the computer is self learning and will make the adjustments necessary......anyways how would i go about remapping the air flow signal?

 

[sideshow]

the computer can relearn just as much as u can get your wife to relearn that

your the boss heheheheh

just one thing i can say never beleive everything u read on the internet or

hear from someone who doesnt know much

relearning does not mean readjusting just means fine tune idle mixtures
using reading from o2 sensor

u can remap air flow meter by fiting a device that sees what signal comes in and adjusts what comes out

but i think they are only for tight asses

do it properly and get a full aftermarket ecu

i do not believe in spending 800 bucks on fitting one of these devices then getting it tuned and only gaining a little

and another thing is ive seen it too many times these things fail
