i git the test pipe from test pipe.com and wasnt happy with the welds so i ground down the old welds and re welded them to my liking then i isntalled the test pipe with new gaskets,new spring bolts and new collector donut!

took it for a quick spin around the block at about 3grand in second gear to let the motor warm up a lil pulled back in garage checked for leaks while running no leaks!

took it for a fast run around the block and when i hit about 5500(vtec crossover with v-afc my check engine light came on? i was like wtf?

pulled off to side of road killed the car started it again and it stayed off one again i hit 5500 on the way back to the garage and cel came on again?

turned it off again restarted it and nothing?
