OK so i have a b16 in my 90 crx hf.. I cant seem to find whats causing the misfire. Ive changed Fuel filter, Plugs, WIres, Cap,Rotor, Ecus, and Dizzy. I have msd on the car and have wired it up withought the msd box straight to the blaster coil. The coil is the only thing i have not changed . It misses with or withought the msd box, so i have ruled that out. Im gonna change the cap tomorow to retain the internal coil.to see if that works. LMK if u all have any info.
thanks

 

forgot to say car does not miss at idle only under a throttle.. No cel and no ecu codes flashing either.

 

check compression

 

x2

 

compression check checked good on every cylinder..175 across. I drove the car last night and it cut off and would not start back for avout 5 min. Ecu was flashing code 5 which is map sensor. Im gonna replace it tonight and hope for the best

 

Why do you have msd ignition.

Stock is just as good and more reliable.

 

ya i know.. im getting a cap tonight to get the internal coil and reg setup back. I bought the car and it had msd on it already.

 

I Changed the map sensor and did another compression check to make sure the guage was reading correctly and its still doin it. Im putting the coil in tonight to see if it makes a diffrence.
