running issues

[benny]

ok guys the honeymoon is over... i'm hearing and noticing things i didn't when i was all giddy about getting a starion again :)

there is:-

a rattle on deceleration
it chokes at idle if i pump the brake
chokes on low rev full throttle ( i.e. accelerating hard from a standing start ) - intermittent
has a fuel leak through a screw on the top of the eci
and it makes power to 5k but goes so quick and soo smooth to 6k am i losing power up there??

any heads up would be appreciated

2.6? If so, you'll probably find it won't like to rev and power will be a bit thin on the ground that high. Even the 2.0 doesn't like to rev standard.

[benny]

its the 2l....

just boggles my mind that its so smooth and doesn't sound like its struggling yet makes no power between 5-6k ... more boost.. lmao

has a fuel leak through a screw on the top of the eci

yeah my ECI did this as well. i think its common on old JA's. i changed the top gasket on it...fixed for a while then fuel started coming out of one of the plugs.

probably needs a rebuild... or i've also heard it could be the injectors too?

i found this on austarion before, very helpful:

nice thanks man.... might just jam some more sikaflex on it til i get the mpi here and sorted... even if i gotta keep it off the raod til then

Hey Marc
Ive had this problem heaps

it chokes at idle if i pump the brake
chokes on low rev full throttle ( i.e. accelerating hard from a standing start ) - intermittent

it turned out to be the injector o-rings were leaking into the
??-injector cup-??, "you know" the thing the 4 top screws, screw
into,,,, at idle the cup would fill up and leak fuel out the screw
but then again a screw leak can be NO alloy washer under the screw,
but I think this one is o-rings filling the cup with fuel

oh once that cup is full, the fuel drips into the TB and makes it run rich
and stumble at idle, this may also make it run lean at full throttle

and to finish I think you have a master cylinder leak if it stalls at idle
while you brake or maybe a stuck non-return-valve (the one way brake valve)
I gone Cheers:Phil.

cool awesome help guys.. and while i'm at it.. can anyone take a pic of the fuse flap and send it to me?? my fuse flap is missing so i got nfi which fuse is which

[redzone]

i've got a perfect eci manifold complete benny if u need to replace yours. see ho u go!

[benny]

that might be the best way to go redzone...

i can get the mani, rail and injectors off a mate for the mpi swap but i got a bit of saving to go for the computer... unless someone on here wants to buy my r31 ... non turbo runs 15.5..lol

not m/c leaking, think u'll find its the brake booster causing the rough idle / choke when pumping the brake.
