[Mk2] [Turbo] rev 2 turbo wont start properly and then dies when you try to pull off

[turboben]

my rev 2 is having a few issues,
when u go to start it trys to fire then dies
when it does eventualy start it idles rough
then when u try to pull of it cuts as soon as its under load
if you can get it driving it missfires badly under load and cuts out and if you stop it then refuses to rev at all and the second you touch accelerater it cuts the revs

any ideas guys??
also stinks of fuel
i was thinking pugs leads and cap and arm
or could it be fuel pump?
ive already tried changing the afm

[2tmike]

Does sound a bit like the afm though...mine did this a few times when the plug worked loose. Might be worth having a good look/test of the cable and plug that goes into the afm?

[turboben]

do i nee3d to set the afm up do you know? the plug looks ok and the wires. and when i unplug it kills the engine

[BTWW]

Check the resistance on the afm pins.

Also make sure the points on your distributor cap are in good condition, and make sure you've got the rubber seal that sits between the distributor and the cap. I'd never had one of these and always had trouble starting/driving in the rain. Fitted a new one a few weeks ago and its been plain sailing ever since. (just in time too looking at the weather at the moment)

[turboben]

checked the afm and its fine do i need to adjust it with the screw?

dizzy cap looks fine and like new as does the arm and no moisture inside at all

[turboben]

had problems starting the car since i got it but seemed to drive ok took it for a run yesterday and this started after about 20 miles and hasnt stopped

[turboben]

so i changed the dizzy cap and arm today aswell as new ngk plugs gapped to 0.8mm with no improvement
checked all vacuum pipes and all ok
checked maf again and its ok and so it all wireing to it
ht leads are on order
im begining to think this is a fuel problem although the old plugs were very black and sooty so id say it over fueling caused by no spark
any ideas???

[turboben]

the idle is ok sometimes but not others and is suometimes at 800rpm others its at 2-3 k
car cuts and splutters at missfires/cuts as soon as its under load

[turboben]

also the engine management light sometimes comes on then goes off, sometimes stays on or sometimes doesnt come on at all or comes on later

Check ALL hoses and clips CAREFULLY from AFM to throttle body.

[turboben]

il go re check all them all again now

[alanmr2turbo]

Have you checked the pipes coming from the intercooler?

I drove a rev3 which idled and drove perfectly till you gave it some and then was like hitting a brick wall on and off. Turned out that the hose had split underneath where it connects to throttle body.

[turboben]

just rechecked all pipes/hoses and clips and all are ok
started car and it idled nice and steady at 800rpm for 5 mins
turned car off for 1 min then restarted and it idled high at around 2000rpm and lumpy witha few missfires
turned off and restarted and it strugled to startcoughed and spluttered then died

[vtecpower]

also the engine management light sometimes comes on then goes off, sometimes stays on or sometimes doesnt come on at all or comes on later

check for error codes dude

[turboben]

no stored codes at all even while the light has been on

[turboben]

would ht leads cause this??

[b16hbg]
