Title: Sticky throttle
Post by: danzigfan on 28 April 2021, 15:00:51

So....I managed to put my project 3.0 omega back together. I ditched SAI gublins, eml isn't on, everything works fine, idles perfectly. No obvious vacuum leak - tested with brake cleaner, breather system clean as a whistle.

Downsides: cranks a bit longer before start when cold
                      It has no insurance or number plate at the moment, that why I can't test it on the road
 When I put it in 1st gear and try to drive off it stops pulling at around 1500 rpm, sits there for a second and then all the power suddenly comes back and wants to act like nothing has happened.
When I rev it up in neutral it revs fine. Problem appears only when under load.
I can't really tell what happens in second gear due to reasons stated above.

I forgot to add it's manual

I hope link works. RPM's are different, but does the same

Looks like the Traction Control is being triggered, at least on the YouTube car. Does it still do it if you disable TC?

TC gets triggered because I was driving on a gravel road. Engine does the same with TC on/off.

Clutch slipping/release bearing sticking?

Driving like that on gravel won't help diagnosis any.

Last night I remembered that fuel inside the gas tank was low and old - from december.
So I took a 10l gas can of fresh petrol and it's cured. Problem solved :y
Thanks for all your help.

Will post some pics at the end of May after I register it for this summer :D

 ;D that'll do it ;)

If it does it again, you may need a new pump. They don't like being run low.

thats one major problem with modern fuel. it doesnt last as long as it used to. thats why i never ever fill a car to the top.
you used to be able to start and use a car that had stood for a fair few years but now your lucky to get a few months !
