Hooked up a wide band o2 sensor to my car today and my car is running extremely rich at 60 psi feul pressure. At wot it goes from 14.9 to 11.8 in the top end. Very rich. anyways thought I would share with you guys. 00G will probably explain in more detail what happens to my car.
How come you guys are running stock injectors just like I am and saying your running lean all the way through? Mine runs really rich.
He might not neccessarily be running rich. From what I've observed the Prelude's run lean across most of the band and then get a little rich at the very upper RPM's.
Actually I run rich through the whole rpm band, except for when vtec kicks in it runs a little lean then goes rich again. Not lean enough to cause any worry, still has plenty of feul.
The sensor is a motec wide band o2 sensor. I took off my cat and put on a obx resonated test pipe. I just plugged the motec into the second o2 bung in the testpipe. Real simple, no cutting or welding. Just cruising my ratio is at 14-14.9, at half throttle its the same.
Ugh. How the hell are you and 1prelude2nv running RICH?
Could you run through your setup once again? Where did you connect the sensor (tail pipe or in downpipe)? What brand/model? Was it 00G's?
This is beginning to piss me off.
Well, i plan on going back to get my car fixed..... stupid installer did something painfully wrong while he installed my clutch. Hopefully he gets it fixed and my clutch is ready to do a dyno run. ill do it. I may get a V-AFC if i feel up to it to see if i can squeese a lil more out of the JRSC.
