Emissions fail
#21
For many years on my 1.6 I was running an old Bell/FMI system with stock injectors and the Bell FPR (since upgraded to FMII with Hydra 2.7). I tried different band aids including a Walbro 255 and a home made flow reduction valve (major pita) and then went to a Walbro 190. The only time I had emissions issues was when either the Cat or the O2 sensor crapped out. the first thing I would do is replace the OS sensor. If you have single wire O2 sensor, upgrade to a 3 wire sensor.

Threads like these always make me laugh.
Hay guyz my emissions show that i'm running too rich because i'm running bigger injectors and a bigger fuel pump on a stock fuel settings withbandaidz. How do i fix it.
You fix it by "removing" some of the extra fuel where its running too rich.
You're all haterz maaan i expected more intelligent answers.
Yup these threads always go great...
Let me connect the dots for you.. the now more powerful fuel pump is pushing out enough pressure where your injectors which used to flow x amount are now flowing a lot more fuel so your car is running quite rich.
