My zed recently decided to present me with a new prob

 

i can drive along in traffic at the usual lack of urgency, but when i try to accelerate slowy the engine completely stalls.if i keep my foot on the gas it kangeroo's until i take my foot off letting it settle, then i can accelerate again.

 

there is also a lack of power when this is happening,

it doesn't happen all the time and seems throttle related

could it be my throttle sensor? have taken it off and it seemed ok.

 

can anyone help :bow:

hiya, my z does that every so often and is getting worse. (dam it)

but the problem with mine is a leaking dump valve which dosent close 100% makes the engine run lean off boost and jerk.

try that it might be the problem. let me know

good luck.

Could be the MAS (airflow meter) ;)

i have a na auto so dump valves aren't a factor thanks anyway

 

already checked my mas and it was ok bit stumped

so its not the throttle sensor then?

could it be air leak after mas

Checked ECU error codes?

 

Could also be bad connections to the PTU/coilpacks. This can happen on a TT (not sure about NA tho) if you get a code 34 (knock sensor fault). Although you won't get 'safety boost' you'll still get the ignition retard if the ecu detects any knock ;)

done the ptu connections last week, they were in need of cleaning but generally not bad,

also checked the ptu

will check the detonation sensor later.

the thing is it totally shuts down to tickover then after a couple of seconds lets you put your foot down again, if you do it any earlier or keep your foot on the throttle it bounces up the road like you just whipped it with a cactus

thanks for the speed sensor a little while ago it worked a treat by the way

it was a dodgy section on the carbon strip inside my tps with about 3mm broken off one sides contact

new one on way

thanks all

Nice work :) Well done

cheers
