Recently accelerator pedal has been giving me the ****s, so this morning I went to adjust all the pedals a little.

So the problem is this:
When the pedal is not pressed, The car idles around 650rpm, if you just touch the pedal a little, it goes up to about 1000-1200rpm. The lowest I can bring it with my foot on it is around 1000rpm. Any lower it basically drops down to 650rpm idle.

So basically I cant smoothly raise rpm from 650 it seems to jump to around 1000 and then be fine from there on. Accelerator cable and pedal is fine, its the throttle valve. Trying by hand to slightly increase it, it jumps to 1000rpm and is fine after that. It seems to be ON and OFF only at idle speed/1000rpm.

While this is not a major drama, its a anoying when you are in low gear and at low rpm, and want to slowly and smoothly accelerate/decelerate. Car starts to jerk, as you cant smoothly increase throttle and feels like is an ON/OFF switch.

So is this a sticky valve situation and it needs to be lubed etc (maybe TB cleaner has dissolved all the lube so its not smooth anymore) or is it some sort of anti-stall mechanism thats set a little too high??

I found this:

Acceleration hesitation (Hey that rhymes)

But there's no real proposed solution

btw I've got it too, I wonder if the o2 sensor replacement fixed it?

Found it was because there was a nick in my ecu wiring that was exposed.. it would ground itself every now and then which caused symptoms as above...

I taped up the nicked part of the wire - no problems since!
