My 90 Crx Dx B16 is bogging or coughing on the low end. It has been doing this since I bought it. It has been 4 months of cleaning and replacing everything. All that is left is the dist. I've heard it will click when it is going ( I assume the shaft gets warped). It has a throttel delay and studdering almost up to around 2500. Any new thoughts would be great..... It is driving me insane!!

 

hmm...well can you explain how it is bogging?

could be dist. (or cap and rotor)

spark plugs

plug wires

maybe even o2...some people say if you disconnect one of your o2's the bogging will stop BUT you will have a CEL

 

It has a almost delayed throttle response. If I try to give it at least half throttle it coughs. I have brand new....Densos, Msd wires, cap, rotor, coil, ignitor. and the list goes on. I swapped out the map sensor because I had the Dx one, it has the correct si one now. It is not throwing codes. I thought about the o2, and I even swapped out ecu just in case. I will try the o2 this weekend, and I have access to a dist I am going to swap also. I am just curious if anyone else has this issue. I wonder if it might be internal.

 

I unplugged one o2 coming home from work this morning and nothing, not even a cel. So I unplugged the other one, still nothing. I thought of a better expaination for the bogging. It feels like it is missing, running on 3 cyl until i get past around 2500. I might have an exhaust leak. I just really noticed it. That might affect it a little??

 

I was thinking about this and have you switched around the way the o2's are connected, I found that that fixed my car when it was doing that stumbling thing. Also check the wiring back to the ecu and make sure it is connected in the right places, just another idea for ya


( Another hybrid hole in the pavement )

 

I rechecked the wirering and changed and cleaned some other plugs. I also rechecked the timing after checking the spark plugs. I fixed by default. Some of the trouble ended up being in the timing. I advanced it more and it settled down. Thanks for the help....
