ok so car has been driving great and pulling hard...just ask some of the guys i gave a ride to at the nyc rotary meet.....
however after getting home i now have a hesitation problem.....

if im at idle and floor it.....i cant get over like 4,500 rpms or boost very high either...
when driving i cant boost at all the car just boggs down almost like fuel is being cut....and a few times the car didnt respond at all to me stepping on the gas and i was like stuck....so i had to turn off and restart and then it was fine

what could be causing this problem???

a quick examination of the engine bay i saw the vacum line on the end of the promary fuel rail was loose and reconnected that but no change in the problem....
what else should i look for???

87 turbo 2 see mods below

 

What are you using to control the fuel and to avoid fuel cut???? If you have 3" exhasut I am hoping you have this controlled, if not that could be the source of your problems.

 

yea i have a racing beat fcd.....actually when i wrote the post i had unplugged the fcd to see if that would change anything and thats when i couldnt get past 4500

now i replugged it and at idle it seems to rev great
but puttin it into gear makes it bog down like that

2 people have recommended fuel filter sayin it is clogged but what else could it be???
im gonna try the filter tomarrow

 

Definately the fuel filter...

 

How are you controlling additional fuel / boost (AFC, Boost controller)? This may not be the issue today but may be soon.

 

dam so no parts place stocks a fuel filter at all
what the heck is up with that
lookin at a week to get one from mazda dealership and longer for parts places like pep boys

 

yea i have no other controller for boost.....just havnt gotten that far.....i know im running rich cuz theres a slight smell of gas from the exhaust so im not too worried about it
but i dont even have a boost gauge yet so im unsure where im at with boost levels which does worry me.....

 

did the fuel filter work??? i have boost problems to...i KNOW its going really rich because i have the wideband and i wathc it go rich..if i floor it in frst i can make to 5K before it hesitates but as soon as try 2nd or a higher gear i cannot get past 3K ROM's....all i did was turn around in a parking lot and took off..then it started doing the same thing...checked ALL vaccum lines and they are fine...

other MODS in sig.!!!!!
