I changed after-market header(exhaust manifold) for my car, after done the job but without put back the o2 sensor in the header, I started the car, at the first time, the car started less than 1 sec. Then stalled, I tried two more times but cannot started(even push the accelerate pedal), and the engine shaking badly. I searched in forum and asked, no one had experienced stall after changing the header. Even using the same brand header with me(I use 02+sentra megan racing header)
the following are the possible processes that I made mistake:
-- I forgot clean up the header when I installed it, but it looked clean inside.
-- I loosen drive belt and removed alternator, but put back no difference. (The alternator off the connection about 4 days)
-- I put the new header on when I removed the old header
-- I hammered the bolt connected with header and CAT pipe couple times, not so hard. But broken the header mount bracket with connect to the engine bay. (It might not be the reason for the start)
Do you have any idea what would be the problem?
have the same problem?
