okay guys and or gals i'm in need of some help.

i have my 89 hatch with a JDM D15b i am having a problem with it. i was comming home from work one day and all the sudden it had no power. It was very slow, like normaly after 3k it would pull hard all the way to redline and would rev very freely. now it stopped and dosent rev as good. it idle's perfect with no problems, i checked for compression its perfect in all 4 cyls. i put new cap,rotor,plugs and still no luck. it cant be the coil or the ignitor because i swapped dizzys off another one that works fine and still no luck. i also check timing and that checks in perfect. its just running like a dog. if anybody can help me out it would be greatly appreicated. thanks in advance

 

Change the fuel filter if problem returns check the fuel pump.

 

make sure u have the right injectors. ive seen people use the obd1 style .
they work for a lil bit then die.

just take a stethoscope and listen to the injectors.

Air filter?
Plugged cat?
Bad plug wires?
T-belt jumped a tooth?

No idea.

 

air filter-no i have a CAI and its good
plugged cat- havent checked that yet will do tomm. what causes a cat to plug up?
plug wires- they are pretty new they are taylor race pro 10.4mm
t-belt- i checked timing and that perfect so cant be off a tooth.

also does anybody know how i can check fuel pressure since i dont have a fuel rail because of the dual point injection??

 

i would check all your grounds. and/or fuel system

Get a fuel pressure gage and install on outlet of your fuel filter.

 

Yea, check your grounds, take a steel brush or some 80 grit sand paper and clean the surface. also take your heat shield off and see if you have some cracks on your Exaust manifold....one of my cars did the same thing...**** ticked reall bad like the valves were bent.....turned out to be as big crack. it was on a gsr and i couldnt figure out why i was runing 16's lol

 

okay heres a new update i took off the cat to have a look and it wasnt clogged. i am still stumped as to why its still funning so slow. it really strains to get above 6k which it used to do with ease. anymore input would be great

 

BUMP
somebody has got to have an answer for me

 

c'mon you guys with all the great honda gurus we have here nobody has a clue?
