[QUOTE="buster1, post: 9889317, member: 30523"] Like the title says , car started running odd , misfires etc , started looking into stuff and found the #2 intake air temp reading 300 degrees and 280 voltsDC which is impossible as the reference voltage is only 5VDC , pump is running , lots of coolant in reservoir and can put my hand on it and keep it there . Check readings with cold car and reading 180 deg and 330VDC , unplug the sensor and -67 deg and 960VDC (again an impossible voltage level ) , checked the sensor it is ok , checked the wiring back to the computer and it meters out fine ( have All Data subscription ) book says replace the computer , took it to the dealer and they find the same things ( took them a day longer) also said some other readings where off and replaced the computer under warranty ( extended ) and said everything was OK , put the genesys on it when I get home and the readings are still the same and the car is running no better . Any thoughts / ideas greatly appreciated . [/QUOTE]
