i did the adjustable fuel pressure mod and put new gaskets on. put everything together and worked perfectly. later in the day the whole car started vibrating and i checked under the hood and looked at the injectors and saw one spraying in a cone and the other was just trickling fuel. i checked the fuel pressure an it was steady at 11.5 which was the same before the mod. my thought is a piece of old gasket got stuck on that injectors. would the small filter on the injector save it or could it have gotten damaged?

 

TBI injectors are tough and usually hold up very well. Check injector connector - make sure that there is no bad connection before tearing fuel injector pod apart.

i will check that out thanks
ps do u know wat kind of flat head can reach the screw of the fuel pressure regulator from underneath (i did the dremel cut on the screw) its a really tight fit

 

sounds like maybe a particle is plugging up the screen on the injector.

 

i have a question, i replace the fuel pump and sending unit on my 90 RS right after the job was done, black smoke started to come out of the pipes and is shocking a little, any ideas?

 

Really should start your own thread about this. Sounds like your getting too much fuel. That would cause the black smoke and engine shaking.

 

so i took apart the injector pod removed the injector and noticed a rip in the rubber gasket replaced it and i rotated the filter screen and it works perfect now. and to adilson delima ur fuel pressure regulator may not be set correctly causing u to get more fuel

 

sounds like you figured it out! great job man!
