You have better emmissions at higher temps. Lower temps give you better BOOMs <img src="/forums/images/graemlins/cheers.gif" alt="" /> 1986 Toyota 4x4 22wEBer Ported EB Offroad H/O Head "Josh Cam" Ported Intake & Weber38mm Carb LCE Header & 2.25in Exhaust RB 1" BL, RS5000, SAW Tbars 2011 FJ Cruiser - SOLD Re: failed emissions [Re: aptech] #814564 06/03/07 08:36 PM Joined: Jan 2000 Posts: 12,153 N. California. USA 4Crawler Web Wheeler Quote why is the 160 to cold. i thought the NOx was to high due engine temp high in exhaust? Lower coolant temps make the ECU try to warm up the engine, so it is not going to be running in the normal operating mode. NOx is made by high combustion chamber temps, which are really not affected much if any by the coolant temp. To lower NOx, retard timing (I run 0-2 BTDC on mine for smog) and also run premium gas and make sure the EGR is really clean inside. r.c.brown@ieee.org TruckEditor@tlca.org Project: 4Crawler 4Crawler OffRoad - 4x4Wire discount code Page 2 of 2 1 2 Moderated by  4Crawler, 4x4Wire, kewlynx  Hop To Mitsubishi Forums ------  Mitsubishi 4x4 and SUV Tech  Mitsubishi Diesels  Mitsubishi ArchiveToyota Forums ------  Early Toyota Trucks  Toyota 4Runner, FJ Cruiser &...  T100 & Tundra Forum  Tacoma Forum  Toyota Tech ArchiveJeep Forums ------  Jeep Talk  Jeep TechIsuzu Forums ------  Isuzu 4x4 & SUV Talk  Isuzu 4x4 & SUV Tech  Isuzu DieselsKia Forums ------  Kia Talk  Kia Sportage & Sorento TechOff Topic Chat ------  4x4 Gallery  Off-Topic Chat  Recreational Access & Land ...  Politics4xForums ------  Outdoor Gear  General 4x4 Discussion  Tools and Fabrication  General Communications  Amateur Radio  GPS and MapsParts Bin ------  Private Party - Garage Sale  Private Party - Items wanted  Vendors, Hot Deals, Group Buys4x4Wire Back Yard ------  Suzuki Forum  AZ Crawler Crew  Cal-Nev Crew  General Ford 4x4 & SUV Forum  General Dodge 4x4 & SUV Forum  General Chevy 4x4 & SUV ForumFeedback & Testing ------  Problems, Questions, Suggestions4x4Wire Staff ------  Forum Moderators  Problem Threads Print Thread Switch to Threaded Mode 5 Excellent 4 Good 3 Average 2 Bad 1 Terrible View Profile Private Message Follow User Forum Posts View Profile Private Message Follow User Forum Posts View Profile Private Message Follow User Forum Posts View Profile Private Message Homepage Follow User Forum Posts
