you look at the powerfc acceleration enrichment page? It could be all kinds of fucked up

 

kyle get your *** here and fix it

 

Have you tested the MAP sensor per FSM?

 

Ok i didnt know this about FD's but for those having similar problems like mine i talked to my dads friend that built engines for mazda circuit racing and he said that some FD's have a problem with the fuel pump. At idle the pump works at 6 volts and activates to 12 when your throttle is opened up , in other words my fuel pump is activating to 12 volts too soon and thats why it runs so rich when i press the gas. the only way to fix it is to wire the pump straight to 12 volts with a seperate relay and install an aftermarket fuel regulator. Thanks for the help guys hope this helps other people

 

The variable fuel pump voltage!?! Are you kidding me!! Glad you got it sorted. Didn't see that one coming though....

 

Umm if the problem is that it's switching to 12v too soon then how does wiring it to 12v all the time fix it? Wouldn't that make it rich all the time? You sure it was running rich and not leaning out?

 

With an aftermarket regulator it wont be a problem the stock regulator is too small to run 12 volts. You have to wire it to 12 volts seperately because if for some reason it starts working how its supposed to then your car is going to be too lean.

 

The fd from hell has been ripping the streets up for months now lol turned out to be the harness to the coils the wires were touching and sending the signal to the wrong coil making it run rich because of the misfire.
