Title: High fuel trims at idle + black smoke Post by: ibizaCUPRA18t on July 17, 2018, 03:58:38 PM Just did a wideband conversion added cores for wideband and all wiring is now ok - no fault codes related to lambda. Voltage tests ok. But after warmup fuel trims reach 20% and idle is very unstable with black smoke. Tried resetting but same happens after 3 minutes. Tried playing with KRKTE but same results. Lambda reads 1.005 - 1.000 most times and voltage is steady at 1.560v - these values should move a lot more? Bad sensor could it be?
What should I look for in logs other than idle trims, injector times, or something else? Thanks. Title: Re: High fuel trims at idle + black smoke Post by: purepower on July 21, 2018, 03:21:05 AM Try to have a look on injection times, MAF reading and Rail pressure.
It seems like injection angles are wrong. But I can be wrong as well. |
