ok i got the check engine light after my car was idling for like 20 mins or so, the fans kicked on. so i check it and its a 43, malfunction fuel supply or somthing. i did a search and i found that i could be running rich.

well i have stock integra injectors with a 190 walbro pump. its a ls/vtec in a LS body. GSR wiring harness. any advice? perhaps change o2 sensor?

TIA

 

Do you have an FPR or fuel gauge? With the 190 lph fuel pump, I would suggest investing in an FPR/pressure gauge to turn down the fuel pressure. Sounds like you're running very rich.

Also, check your spark plugs and see waht color they are.

 

yah i have FPR and guage. well the light is off now. wierd how it came on. im running 48 psi with the hose off. i am going to lower it down to around 40 or so and see how it runs.

thanx for the help

 

hmm. with the hose off that is where I am as well, that's where I'm supposed to be though
