i've been having a few problems lately with my 1.6 efi zook..
everytime i take off i nearly stall it...
if i plant the accelerate foot.. the car cuts out!
i have to get 4-5k revs to take off...
then in second gear once changed it chungs... like a 5 to 6 bunny hops...

now my dizzy is all the way advanced and helped for awhile
is it possible that i mite be a tooth out..
or is my car just thirsting for petrol??

cheers

[joeblow]

who did the efi?

[Fatzook]

why is your dizzy on full advance?

Have you tried setting your timing to OEM specs?

[Verm1n]

my dizzy is fully advanced cause that is where the car seems to run best.. if i retard it, it doesn't have enough power to go..

[Verm1n]

me and my bro put the engine in.. has been runnin quite well since the install

hey mate i would be checking all timing marks.

i had an astra that was one tooth out on the exhaust cam and did similar had no power.

[Verm1n]

yea i was gonna head in that direction.. i was going to advance it a tooth and retard the dizzy.. c how dat goes???

[89_tintop]

there is no mods to the engine is there?

i would stick to the factory settings and make sure all is sweet there.
i dont like messing with advancing or retarding via the cam/crank teeth

[Verm1n]

no real major mods..
however it is a 1.6 fuel injection in a 1Lt zook ute
i will check all my timing markings and go from there..

[jonno_racing]

start with your basic cam timeing... then move on to ign timing... then go from there.. what do the plugs look like?

[royce]

So it ran fine then went shit and you had to advance the ignition to get it to sort of go again?

I would replace the cambelt, set it to the factory marks (I reckon its slipped) and put the ignition timing back to stock and go from there

[Verm1n]

will have to have a look this avo at it..

jonno_racing
yea will ave to check the timing the plugs are pretty average..

royce
that is the story.. ran good then went shit.. advanced the dizzy ran good for awhile now is shit gain

[Verm1n]

is there any possibility it could just be a sensor??

could it be the air flow meter?? - crap inside it?

I'll still bet it's the cam belt. Sounds like it slipped a tooth and ran like shit till he advanced the timing, then slipped another tooth and it runs like shit again. If it slips yet another tooth it won't be running at all.
