Hi all, 

 

As stated the  si ive isolated to bog down on hills and in higher gears to control revs, flat ground and down hil are ok. just when its under load.

 

This seems to point to Fuel pump flagging,

Double check your fuel pressure regulator.

Hi thanks, spark plugs were cleaned which help it, but some surgeing on acceleration will change plugs

Not a master mechanic but what I've found is that fuel pumps are either go or no go.

Forgot about the FPR. 

How long have you owned it?

Buy it from a friend? if so, ask about previous issues.

Glad you posted this, I have almost the same issue on my 86' Si. Will check the above this weekend.
