missfire?

So, driving along the n1 my little sentra decides to embarrass me....... The car suddenly lost power, then roared back to life with an ear shattering backfire, needless to say i nearly crapped myself. Eversince then it has been doing it on a regular basis and jerks while driving. Now, heres what ive done so far (without any success i might add): replaced fuel pump and filter, replaced injector o rings, replaced plugs and coilpack tips, re adjusted the cam and ignition timing, sealed every possible air leak on the intake and made sure that its not an earth issue. So i beg, any ideas? Its a ca18 running on a diktator system. 😕

Diktator does not have sequential fueling a badly mapped ecu could cause bad backfires you diktator could be faulty. Did u replace plugs?

This is just a guess, but check your module. Sounds like its losing spark when it dies down....If that doesnt help then it might be the dictator, borrow a dictator from someone and copy your mapping onto it and run it to see if there is any difference.

Check if your hall sensor isn't loose (the magnetic pickup, pos)

Have you replaced the fpr?

You have checked the earths so now check the positive feeds to the ecu, if you rev counter needle drops when she cut out then you have a loss of power to the ignition. This normally results in a backfire due to unburnt fuel in the exhaust.
