Plymouth Voyager 1987 2.2 carb. Checked EGR and is working fine got the idling engine to shake more when I applied vacuum to EGR valve, the thermal valve is working as well, just tested. Did the combustion chambers cleaning after the e-test. Background: When van is on 2,000rpm test, NOX was failed along with CO. Both are not too far, like 100 points above limits. I had the timing gun on it when I was testing the EGR vacuum, I get some vacuum at 2,000 rpm but get more stronger if I go above 2,200-2,500rpm. If yoiu have info on EGR vacuum strength in Hg at 2,000 RPM on a carbed 2.2, please let me know, this is IMPORTANT. Thanks & Cheers, Wizard |
