Spark Plugs Fouling ( need help)

:
2003.5 Sunlight Silver MSP #1776
(help) I need help i put a circuit sports j-pipe on and ran the car for 3 to 4 days without mil eliminator then got cel. So i put one on. It was fine for about a week. it was hesitating bad under high boost. so i finally figured out it was the plugs they where all fouled up. so i replaced them and also took j-pipe off but left mil eliminator on. about 2 weeks later plugs where fouled up again and same problem. I can't figure it out. should i take it to the dealer? (help)
 
wow
never heard that before.....
did u recet the ECU after putting the downpipe on?
then again after taking it off?
then again after repplacing the plugs?

what exactly do u mean by fouled up?

what problem returned? hesitation or CEL?

if the cell is back, dont take it to the dealer yet.
go to pep boys and have your PCM read for the code.
it might not be the exhaust system at all.

are u flashed?
