Drinking fuel??

[ryana89]

Could it be the Air Flow Sensor (Or AFM) by any chance?
I noticed the flap/door on mine was a bit sticky but nothing worth worring about.
When the car "wont rev" how does the engine run? Does it cough/splutter or run rich (black smoke)?
Does the rpm stay abnormally high at idle when it occurs?
When does it occur (just randomly or when its hot/cold).

Sorry for late response, had to take the car for a drive myself to explain the problem a little better.

Regardless if the engine is cold or warm, when you press the throttle pedal, the engine wont respond for a few seconds, then it would return to normal. Once its moving, the engine responds normally. I don't think it would be the air flow sensor, only because once the car is moving it doesn't splutter or cough.

Check the resistances on the idle switch on the throttle body, possibly faulty.

How fast does it idle?

same thing was happening on mine i changed the oxygen sensor thinking it was that didnt help but my dad leaned the air/fuel out a bit on the afm and that seems to have fixed it.

It didn't idle well, so we had to lift up the idle a little bit. Sits on 1500 now, only cause it would of the problem. We are avoiding to not drive the car because its dangerous to be on roads like this.

How do you lean the air/fuel ?

Have you ever had it idle properly? I you have don't go changing settings to make it run better, go after the cause of the problem. You may/probably have an air leak.

Sounds to me that the throttle closed switch is sticking in the closed position. If it does that you only get 8 degrees of advance and that essentially stops the engine from accelerating. If it opens up after you hit a bump then the engine will respond to throttle position.

My advice is find yourself a mk2 Haynes manual and follow the set up procedure in that. Don't look for the forum to give all the answers, there's not too many people on here that have ever had a K-jet, let alone a 16V, which is quite a bit different.

Yes, reading helps.

Thank me later.

This answers all my questions.

Ta for that mate.

I reckon it sounds like a vacuum leak too.

2nd choice would be to change the Air Flow Meter. Do not prise the cap off and tinker with your one.

3rd Choice would be ECU which is common to fail on an 8v Digi.

Cheers mate,

Will check it out and get back to you guys.
