Hey fellas,

2 weeks or so ago, I was driving, I decided to have some fun cause my sis was next to me in her SV6 lol... So stalled it up, didnt take TC off as I wasnt intending on doing anything too dramatic.. Took off, TC kicked in so I backed off a bit, then nailed it... After that and till now, everytime I nail it, it feels like TC is coming on, the TC light doesnt come on its just feels like it, kinda farts, jerks around a bit and drops power.. I spoke to someone who said it maybe my tyre pressures were off and the car was sensing it and applying the TC, the tyre pressures were off, but since I have been keeping an eye on them and its still occurring..

Just had a service etc... new plugs bla bla bla.. Car was fine after the service, so nothing to do with that...

Any ideas?

What do you want to know?

Basically I took off harder than I thought, TC kicked in and now whenever I boot it it has the same feelin of TC turning on, but the TC light doesn't come on. It even happens when I turn TC off..

Both are possible.. Last service I had I had the plugs changed and I had an issue where we thought the coils were playing up but it wasn't them.. Valve springs are Nizpro ones but were installed years ago, could be a possibility but the car hasn't seen over 250rwkw's so I'm thinking they should be ok..

Ok sweet, will look into it. Would crap coils cause an increase in fuel usage too? Not a lot but noticeable?

Turned out to be a blocked fuel reg.. Was pushing 6bar instead of 4, so that explains the extra fuel usage and obviously running way rich which was causing the drama..

Thanks for posting back with the cause, someone may benefit from this later on.
