Hey whats up guys I bought my Honda back in February it has 93k miles and and I sounds like crackling in the motor. now engine light came on and its a 1399 and 1379 code. cylinder 3 misfire. runs fine when cruising but when come to a stop it starts chugging. bent valve?? this is right after I got the timing belt done too

P1399 and P1379 aren't supposed to exist for a 98 Civic. However, a P1399 is usually a misfire code.

That makes it likely.


Compression check first
Then a leakdown test if compression is low, figure out where it's losing compression.

Decide what step is next based on those results..

my mechanic did all those and everything is good. its gotta be a head gasket or valve. should I just a get a used motor or have it fixed? what do you think is cheaper? you can hear the ticking when its idling too.

My compression gauge is not marked in any scale of good.

How can this be? Your mechanic declared "everything is good".
SURELY his gauge would have said BAD if one of these was amiss......Amirite?
Fix what? What is wrong?
Remember now, your mechanic declared "everything is good".
Accurate diagnosis, along with educated and informed decisions.
Then correct and effective repairs.

So.....What did your mechanic say about it?

Self fulfilling prophecy is in effect: I'm sure it will.

I had a similar problem with those exact 2 codes, what it turned out to be was the wire going to plug 3 got loose over time and wasnt making very good connection.
