Why is my car flatspoting?

starkersEB · 28-03-2006, 01:40 PM

Lately for some reason when i go around a corner and im giving it a bit my car will just sort of flatspot, i was thinking it was just because my tank was a bit empty and wasnt picking up properly but it has happend also when i have a fair bit of fuel. She does seem to be running pretty rich at the moment for some reason so i guess it could be fueling up too much also. Any ideas guys (other than getting a tune i have bugger all cash atm lol!!) Cheers

Mine does it when its cold, i start her up and drive about 100m and its a giant flatspot, no power at the foot at all. Drops right down.

I got that straight after i got my extractors on..

Yeah same, the extractors seem to be causing me more harm than good at the moment. I did notice the change after the installation of extractors.

well between 60 k's and 80 will be the bottom of second.....without cams etc thats why its going no where lol

the extractors also may be robbin torque for power

So if we had an upgraded cam, should this correct the problem of the extractors causing these flat spots?

Yeah I was thinking that, it's not so bad when I haven't got ECONOMY on but when I do she's a little slow

I get exactly the same thing. Luckily I take it very easy when it's cold coz you wouldn't want that shyte when you're jumping into a gap from a T-intersection. Only happens when it's cold and power will come back if I lift off and back on again. Sometimes get a bit of a stutter when the foot goes back down.

I don't have extractors yet, just the offset Redback and no resinator. Can't remember if it happened before I got that done.

I guess ill just take it easy for that small amout of time when it does it, but yeah now you mention it i remember it didnt happen before i got my extractors and exhaust system done.

Once you are at 80 the car should be sailing along fine .. I'd be heading for a fuel filter as a cheap fix

starkersEB · 28-03-2006, 02:08 PM

I have extractors and cam so i spose one of these could be a cause if this. Also though mine only happens when cornering hard so it makes me think otherwise.

advance timing?

What you said had just got me thinking because i have an AU motor in my EB so i had a look and it seems i have a dizzy on it does this seem correct?

Racecraft · 28-03-2006, 05:38 PM

yes it would be the EB/ED dizzy in an AU block, remember although you have the AU engine in your car it still has the E'series looms.. So you couldn't be running the AU coil packs without a heap of messing around

starkersEB · 28-03-2006, 07:40 PM

kay no worries might have to get the ol gun out and see how i go thats if i can get a gogo gadget hand in there to move the dizzy lol!!! or maybe just fork out a few bob and get a proper tune :voldar02:

santoitaliano · 28-03-2006, 07:42 PM

as far as you can go in our cars as tuning goes is base idle and ignition timing...
