Hi All
I have a 1990 accord, she runs fine most of the time but you will be going down the road and it will lose accerlation, if you floor it it will shift down and take right off (does pop ) I have changed the fuel filter but no help. It does a throw a 43 code Any ideas?

 

Maybe anything from water in the fuel to timing.Have you had the timing belt replaced reciently?

 

No I have not, tried some fuel cleaner but just put it in. and just did a complete tune up and new distributor.

 

Could also be a bag injector,try running Seafoam in a tank.
