Engine Problem

[kilmo]

This is a weird one to me, but may be a known problem for some of the wiser heads out there.....

Scenario: Sitting at the lights, you decided to give it a bit as the speed limit up ahead is 100km/h. So you do you get to 120km/h and you feel what can only be described as a vibration and a burble when the accelerator is on....you go off gas, the revs drop and the problem ceases...you put your foot back on the accelerator, and the vibration/burble comes back.......after approximately a minute or so, the problem goes and it appears to be back to normal running.....

This has happened to me on a couple of occasions and I'll be f**ked if I know what it is....

Any ideas ????

Does it always happen under load and at any speed? Could be a coil pack..

tuned or stock?

if tuned what are the gaps set at?

When were the plugs last changed?

When was the fuel filter last changed?

"after approximately a minute or so, the problem goes and it appears to be back to normal running.....

"

So after a coulple of squirts it then goes away, and wont return even when you give it a squirt the third or fourth time etc?

What fuel are you running?

does it happen when its hot?

It sounds like a spark or fuel prob to me. There could be a fault code thrown into the ecu, so if you take your car to someone who can scan for codes this might help.

good luck mate
