I bought a 88 civic with a d16a6 dpfi yesterday. The only problems i can find are it leaks oil needs a valve adjustment and it has NO power at low rpm's. I did my dizzy cap and rotor replaced the spark plug wires messed with the dizzy timing cause some one told me to and did a oil change. Nothing helped. What is this caused by.

 

don't just randomly play with your ignition timing, you have to set it with a timing gun to 16* before tdc. you also may be feeling the lack of power due to the engine is a slightly larger displacement than the d15b1/b2, and could be choked for air or fuel since the a6 is technically designed for mpfi set up.

 

could it t be the dpfi intake manny was put on the d16a6 motor how could i tell???

 

dpfi:


mpfi:

 

no i know what it looks like. my ? is can it just be the manifold that is wrong. that they put a dpfi intake manifold on the a6 head??? Now i know all about the dpfi to mpfi swap and what is needed. how can i tell if it is a b1 b2 or a6 head

 

dont you have to change the head on a d15b1/2 to mak it mpfi or do u just have to change the intake manny and the wire up and such

 

no you keep your d15b1/2 head. you can swap the si cam over, but you have to use an adjustable or y8 cam gear to get the timing correct, all though i have heard that the d15b2/b7 cam has the same lobe profile as the a6 but is cut differently so you don't have to make up for the 4 degree's difference due to deck height difference.

 

I hate to re start the thread but i need some help. I just rebuilt my motor completely and its running sounds good minus a vale thats ticking ill fix that tomorrow.but i wanted to know if 2 broken vacume lines and a bad map would cause rough idle poor power and stuttering. also what to know what i may have done wrong when i put my clutch in is it now shuttering a little and i did it according to all data specs. If any one has any ideas let me know whats up. thank you for the help
