Ok guys a curve ball for you,

The idle and drive on petrol is a little left field.
The car is duel fuel.
On gas it is perfect (admist a little less power for my liking :wink: )
On petrol, the idle is hunting really badly, If i hold the revs up to around 2000-2500 rpm, the engine starts to shake, when driving on petrol, the car is running rich, very very good pickup but blows ALOT of black smoke. If i have to stop. i.e. at a set of light and do not have my foot on the acc. aswell as the brake, the car will stall.

I have replaced the spark plugs and leads (8.0 mm eagle leads), replaced the O2 sensor, replaced the MAP sensor. From my looking, I cannot see any vac leads off anywhere. Replaced the air filter, replaced the fuel filter. I know that the fuel is getting to the injectors. Oh and BTW it is a centre point.


I am at a loss as to what it could be. I even tried to re-learn the ECU like in my prev car (EF) but to no avail. I need some help as sometimes i use petrol but the cops around here dont really like seeing black so i need some help as to what it could be please?

I try and use petrol as much as i can but with it playing up like this, i cant.

If it was the timing, then it would have the same prob on gas. The injectors were my next point of call, just wanting to hear other ideas first as can be expensive.

Yeah, I'd go the injectors to start with, fuel filter, and get the flow & pressure test for the pump.

The test should only take about 1/2 hour to perform for the flow & pressure test.

You can get exchange ones from Repco. The are called Aznew. They are about the same price as getting them cleaned & tested.
