installed my l/t headers and o/r h-pipe today and went to start it and it wont run. its flooding it out now. tried reinstalling the tune and it didn't help. two codes coming up
p0102 mass or volume air flow low input
p0443 evap. emmisions system purger control valve curcuit
pulled all the plugs and they are all soaked in fuel. even worse is the oil guage isn't reading and the dash says low oil pressure. i removed the filter and cranked it over and oil comes out but not alot. i think the sender may be bad but what could i have done to make all of this go wrong. it has a offroad h-pipe. do i just need to get it tuned for that?????

 

did you get a new tune? if so, did they turn the 02's off?? and did they write the tune for longtubes???
