i stuffed a set of 42's in my 91 940. bypassed the resistor block, reset the ecu to let it relearn. its got a rough and rich idle to the point it makes my eyes tear. i tried stuffing the guts of my 016 maf in a 3in tube but it made the car run worse. i stuffed the factory injectors back in and it runs smooth again, just down on power. i drove it around with the 42's in and the idle bumped to keep it from stalling in hopes it would relearn to run with 42's but after about 100 miles no dice. has a new o2 sensor factory bosch, idle air and tb are spotless and working properly. coolant temp sensor is good.
any ideas?
