bogs under load, first thoughts were vacuum leak of some kind. smoke tested it yesterday and wasn't able to find any leaks. Thanks in advance for any help.

sounds like the MAF is causing the system to have wrong air/fuel mixture...your probably bogging down because not enough gas....feel like its running out of gas??

the p0102 code is for mass air flow sensor.....goto http://www.obd-codes.com/p0102 for more info...

Basically this means that there is a problem with the Mass Air Flow (MAF) sensor or circuit. A more technical description would be that the MAF circuit had lower than expected voltage (air flow).

if maf is not showing enough air intake...then PCM would reduce fuel going into injector banks on both sides of intake to compensate.....this would mean the combustion fuel/air mixture would have a normal amount on air..but incorrect (reduced) amount of fuel.....that would throw lean codes on both sides of exhaust O2 sensors(the p2096 p2098 codes)

try cleaning MAF and see if that helps....check http://www.therangerstation.com/tech.../CleanMAF.html for more info on this....your MAF should be the same or similar to the one shown........

once you clean MAF...clear codes and drive it...see if codes come back....
