i have 1997 honda civic cx and can't figure out the problem.car is hard to start then when it starts idle is fine rev it up and lots of back firing won't rev past 3000 rpms and at 3000 rpms punch it and bogs hard.please need some help.also changed plugs,wires,and fuel filter.

 

Any cels?

 

yes

 

What are they?

 

Are you being obtuse on purpose? Pull the codes and tell us what they are. If you don't know how check the last sticky at the top of the forum.

 

check engine lite on won't flash and scanner won't scan

 

Jump the service connector then. If you cannot pull codes we can't really help you much. Especially since getting info out of you is like pulling teeth.
Check your timing.

 

jumped the service plug and nothing

 

WHat do you mean "nothing"?

 

cel doesn't flash no codes

 

Is the cel off or solid when you ground it?

 

lite stays solid

 

Prob bad ecu if your sure your jumping the connector right. Have another ecu you could try?

 

When the key is turned to the ONII position it stays solid? Are you sure you're jumping the connector correctly?

 

yes lite is on solid with or without jumper

 

Swap ECUs.

 

aside of a bad ecu any other suggestions

 

Inspect the inside of the distributor and check the mechanical timing.

 

inside the distributor looks fine but from looking on the web saw other cars with same problem being a bad distributor

 

Is the inner cover missing?

 

Still hasn't checked timing?

 

inner cover is still there and how can i check the timing.maybe the car jumped timing

 

my brother had a problem like this in his da it was the tps or map he just changed the whole throttle body if it revs up all the way when u dont step on it just rev normal than were in the same boat just mine bogs after 4000 rpm

 

Since the search function on your computer isn't working either, it sounds like time to spend $20 on a Chilton or Haynes manual.

 

bogs hard if you don't let of it stalls
