obdII scanner problems (help me please)
so i have a 98 4.2 f150 w/ 5 speed. to my dismay, i got a check engine light the other day after the truck started acting funny. it wont hold and idle after i have been driving for a few blocks or so. i can start it in the driveway after a few hours and rev the crap out of it and it wont die (it comes close though). but when i come to a stop it will stall. it fires right back up, but i had to do some 2 footed driving to make it home. anyways i borrowed a friends scanner to see what the code was (the scanner is this one) and it wont connect to the truck. i hooked it up to my wifes car and it works on hers, but wont on the truck. i followed the instructions and it still wont display the little car icon (signifying it has a good power source from the vehicle) basically its playing like its not even hooked up. are there any tricks i am overlooking here or that i dont know of??? any ideas please!!!!

For the engine problem it sounds like a EGR , may just need cleaning. The scanner may just be having a problem with connecting to your truck. I have 3 different scanners/code readers and sometimes my cheapest one reads were my expensive one has problems. Go to AutoZone and let them try to read it.

ok i got it to download. not exactly what mgdfan said, but it got me thinking about fuses and the slot that was supposed to have a 5a fuse for the dlc (slot 12) didnt have one, so i put one in and it worked like a champ. so thanks mgdfan
the code that comes out is p0102 any clues. according to the book that it came with its a generic code for "Mass or Volume Circuit Low Input" so i have no clue what that means. i assume it means bad maf, and that would make sense to me when i think about the symptoms. any ideas

Try cleaning the MAF - use CRC MAF cleaner (don't use brake cleaner - too harsh, may leave a residue)- don't touch the actual sensor.
