Need help BADLY, as everyone knows i have a crazy idle. I need to get it fixed quick. 19 is the error i got and my idle sucks ass, and ive used two different TB....... Injector #3 control circuit Harness and connector / Injectors any suggestions? i replaced the injectors, fuel rail, fuel filter, wiring to the injectors. Could back pressure be a factor in a rough idle? because my fart can was put on weird by a show car shop and its a weird Z and i was thinking it could create nasty back pressure. I really need some help on it. The timing looks fine. Everything looks good on it. Ive went through all the vaccum hoses and they are fine. But when we spray carb cleaner in it the car smooths the idle out like it isnt getting enough fuel. I had the soud clip on the site and noone really knew what it was. What are the possiblities? i need help bad

fuel filter?

um yeah, i put that i replaced THAT.

Rockin the INDY DSM club

didn't see the fuel filter in there on the first glance

heres a couple things to check on: hook up a fuel guage see what pressure your at or maybe see if you can swap in a buddies fuel pump..

when you did the rail did ya take care of the regulator too?

the map sensor could be bad giving weird reading cam sensor would be my next choice..

how did you check the vacume lines??

could have a intake leak at the manifold ive seen that before (intake to head)

cam gears could be off..

next thing is EGR that you can play with.. msot people just block it off
