I am having troubles! While I am not coming up as a gross polluter, I have tested 2 times and cannot pass the 15 MPH test, even after fixing some exhaust leaks and installing a new CAT.
Here are my numbers on the last test:
15mph: HC: 129 MAX 110, CO 0.14 Max 0.71, NO 73 MAX 772
25mph: HC: 85 MAX 85, CO .0.14 Max 0.59, NO 36 MAX 711
Barely passed HC’s at 25 MPH at 85 ppm, Failed the 15 MPH at 129 ppm
Ive done the oil change, sparkplugs, wires. Car runs well!
I am running blue top injectors, adj Fuel Pressure reg at 43 PSI, and a Walbro pump, ramchargers chip to match the injectors.
I have passed with this combo 2 years ago.. No real changes except for the pump and regulator.
I have read discussions about turning the pressure down to lean it out, but other say this reduces atomization and makes matters worse.
Please! Any help would be greatly appreciated! I'm not opposed to putting the stock injectors back on and getting a new chip, if that seems like a sure fire way to passing!
Thanks,
Tim
