maf question
maf question Quick question , I did my71 nova lq4 conversion and had my computer tuned by frost via mail order. but the psi harness required that I use a different maf and o2 sensors than I had from the 04 van . I got the car running with the new stuff but she is running really rich and the st fuel trims are through the roof . is it from a vac leak or do I need to get the pcm reprogrammed for the new sensors ? or where do I go from here
ps :I did do a head and cam swap while the motor was out and steve had all that info but I didn't know about the sensor deal with the new harness
Thanks,
Keith

truck/van uses an 85mm MAF sensor with built in IAT sensor
cars typically use a 78mm MAF and a separate IAT sensor
Not to say there isn't a vacuum leak but if it was not tuned for the correct MAF sensor, it can cause the fueling to be way off.
