Did the swap not to long ago and the car started to act up going to virgina (7 1/2H) and half way there the car started to misfire Like if it was running out of gas. no check engine light on. did have it once but that was the O2 sensor. Don't know what else it could be I have chged the following and still the same issue. :

Gas Filter
Spark Plug Wires and Plugs
External Coil
Rebuilt H23 Dizzy( I wonder if this could be the problem)
02 sensor (Fixed the check engine light)
Fuel Injectors from a F22B to a F22A

Someone in the NYC have a F22B OR H23 Dizzy I can test ?

I need to get the fixed!! Been driving like this for over a month

also I hear a clicking sound right before it misfire's behide the firewall. can that be the Black box behide the mani ? everytime it clicks it misfire's

 

In for the answer

 

That Black box under the intake manifold? I would think not. I would check into the Dizzy, I had a stuttering issue with my DOHC F22B. I swapped out the Reman'd dizzy for a new one and the issue went away. (I bought an H23A and a f22A and swapped internals as I have a 91 which is internal and not external as yours.)

 

when you did the swap did you use the f22b intake manifold or the stock f22a one?
