efi throttle body help

[wedgey]

hi all

have changed over from my

2.8l nissan standard inlet manifold,standard 50m throttle body and extractors

ems stinger computer

new ones replaced are

2.8 nissan naps inlet manifold.65m throttle body of a ford and stewart wilkins extractors

my problem is when i started the car tonight it reved to around 4,500 and would not idle back down

tried the adjuster screw but that did nothing

what would you guys suggest i do

thought that i may disconnect the computer so it could reset itself

but any help would be appreciated

thank you

robert

Have you changed the ECU as well? If not, check all sensors, I know this sounds stupid but I had endless probs withmy car because the connections to the thermotime switch and temp sender were bad.

Cleaned them up (both the terminals and the plugs) and it was all good.

Only other things I can think of are the throttle position switch and maybe the air flow meter (if you're still using it)??

thank you for the help

ended up finding the problem

the adapter that i made up had the studs in it

when i tightened up the adapter the stud pushed out against the manifold

letting it suck air

thank you

So did has the NAPS manifold made the difference you were looking for? Could you send me a pic of your setup so I can see how the my old manifold now looks - I have not got to the point of using the brackets that I got as part of deal/purchase/sale/swap thing we did last year

hi

have changed the gearbox and diff from a 240k

stewart supplied both so it has not been on the road for a few weeks

fitted the longer extractors from stewart wilkins

your manifold and throttle body

running a falcon cable for accelerator

it does seem to rev up a lot quicker than before

its going to the muffler shop monday

for 2 1/4 inch exhaust

then up to stewart for the tuning and dyno

hope i get to that magic 100kw at the wheels

when i got 90kw out of it it had only done 1,000k

it has loosened up i bit now

by the way did you end up getting the manifold with the six throttle bodies from melbourne they looked unreal but could not afford a justifer the price

but if i had the money they would be on soon as i could get them

thank

robert
