so a friend recentley turned my engine maint. light off and now i need it back ON...ever since i put on my new greddy headers ive been having probs..

i put them on but couldnt get the headers to seal properley between the downpipe and the catlytic converter and just fixed that today with a new donut seal....since last night it has been running rough like the o2 sensor is ****ed up or maybe running on one cylinder.....

any help is much appreciated,. thanks

dave

 

maint req'd light comes on every 7500 miles or so. it's a counter, nothing more. it won't affect anything by coming back on. are you sure you don't mean the check engine light?

 

oops i ment check engine light heh my bad
