Most routinely, the air-fuel ratio will be measured through the oxygen sensors calculating the amount of oxygen and carbon monoxide present in exhaust gases. The ECU will try to compensate, by reducing IPW, but if fuel trim goes over -25% or so, the ECU interprets this as a malfunction, setting a DTC (diagnostic trouble code), Idle vacuum should be 21-23 in. truenoteno Audio And Security 7 06-29-03 08:19 PM Posting Rules You may not post new threads You may not post replies You may not post attachments You may not edit

Note: The use of "oiled" air filters can cause the MAF to become dirty if the filter is over-oiled.

Measure fuel pressure and then shut the engine off. MAF contamination could skew air intake measurements, therefore skewing fuel injection calculations. also i have a system too rich bank 1 and system too lean bank 2+ intake air temperature circuit high input + the maf sensors low input.. Thx for the reading.
