Thanks for the previous info on the emissions CRE; I recently did a retest and the NOX passed (barely, 2.23 of 2.5), but the CO and the HC still didn't. HC was at 3.96 of allowable 1.6 and the CO was 117.31 of allowable 15.0. The idle is still a little high, but it seems to be running rich. Any ideas? The timing is at 10@ BTDC, and I have checked and set the TPS, checked the ISC and the air flow sensor settings, etc, according to the factory recommended settings/values. Any help would be appreciated as to where to look/ what to fix/reset/replace. Thanks!
