Subject: fueling problem by bam on 2014/5/16 15:01:30 Ever since I put in my LT4 hot cam and LT's I have had a miss that won't go away. It is intermittent and very annoying. Yesterday (after I fixed my ABS) I decided to switch my wide band 02 from the pass side exhaust to the drivers side. I have been tuning with the 02 there (on pass side) for 2yr and have gotten the A/F very close to perfect. When I made the switch the readings were 16/1 A/F ratio and even more lean at times on the drivers side. WOT is around 13.7. I figure it must be either an injector not working properly, bad drivers side 02 (both were brand new and heated after I did the LT's) or the computer. Any thoughts? I have switched injectors from the new ones (bosch III's from FIC) to the old ones and it made no difference. Also I split the pass side 02 wire and ran that back to the computer for a while and also no difference. I am leaning toward something wrong with my ECM. I have a new Delphi 02 on order so I will replace that and see what happens. |
