Pokiou Posted 16February, 2017 Report Share Posted 16February, 2017 Hi fellow Porsche owners,I recently noticed something on my 996 C2, when i release my throttle after some acceleration there is a delay in the response from the throttle. maybe .5 to 1 second delay. I don't know if this is normal or if its something i should be looking into getting sorted? Hasnt affected anything but i think it might help with smoother gear changes.Any insight would be great.D.

Pokiou Posted 17February, 2017 Author Report Share Posted 17February, 2017 Nope its cable. Link to comment Share on other sites More sharing options...
edgy Posted 17February, 2017 Report Share Posted 17February, 2017 Ah I am thinking GT3. If the pedal is returning properly, could it simply be a sticky throttle body? Link to comment Share on other sites More sharing options...
IanJ Posted 17February, 2017 Report Share Posted 17February, 2017 I had a similar problem in my 924S. It was cable tension. I replaced the cam with a better responding one and tensioned the cable and didn't have any problems after that. Not sure if you can get a similar mod for the 996?

Pokiou Posted 17February, 2017 Author Report Share Posted 17February, 2017 Hmm, well the throttle is not sticky at all its really smooth. But when i lift off, it takes like 1 second for the car to respond.. maybe i need to see if the cable is loose on the throttle body. Link to comment Share on other sites More sharing options...
Jim45 Posted 17February, 2017 Report Share Posted 17February, 2017 Ah I am thinking GT3. If the pedal is returning properly, could it simply be a sticky throttle body? Early C2's were the only one's with cable throttle - all are electronic throttle after 1999......Jim. Link to comment Share on other sites More sharing options...
Macca Posted 17February, 2017 Report Share Posted 17February, 2017 I guess I would start by cleaning the throttle body air inlet while at idle. (just get some TB cleaner and spray etc) I had a look through some forums about the "potentiometers" , and cleaning the tracks. (disconnect the battery before pulling the TB apart) Hope this helps hilst chasing a vacuum leak I removed the throttle body from the car and took it apart to have a go at cleaning the potentiometer. Pretty easy to do really. Once the throttle body is out of the car, there are 6 clips that hold a plastic cover onto the side of it. Remove these by prying off with a thin flat screwdriver - do it from the metal side or you will damage the plastic. Carefully tease the plastic cover away and inside you'll see some tracks and metal brushes. I cleaned the tracks using some IPA and a cotton bud. The cotton bud was black by the time I finished so it was definitely dirty. I've not had a chance to take it out for a drive yet, but I'll post an update when I do.

Airhead Posted 17February, 2017 Report Share Posted 17February, 2017 How far do you travel at 60 kph in one second?60 kilometres per hour = 51.3 feet per second.(15.63 mts). How long is a 996? Think I'd get it fixed. Link to comment Share on other sites More sharing options...

Pokiou Posted 14March, 2017 Author Report Share Posted 14March, 2017 Hey Macca, I didn't really have to much time to take it past the workshop due to getting stuff ready for the Melbourne F1. In the mean time i put a cable tie at the end of the throttle cable where the lead stopper is. This took up about 90% of the slack and started to ready 98% throttle on the software when i connected to the OBD reader. Now when i lift off its not as bad. It feels a lot more natural to be honest. Throttle response it a lot more crisp. I did take her for a drive up to healsville yesterday and around the twisty roads and it felt pretty good. I wish i had more bottom end power lol.

dan_189 Posted 16March, 2017 Report Share Posted 16March, 2017 There is a throttle position reset procedure but it might only be for e-gas cars. As for bottom end power do you have any aftermarket exhaust parts like cats or headers? Link to comment Share on other sites More sharing options...

dan_189 Posted 20March, 2017 Report Share Posted 20March, 2017 Few things can be done:- Clean throttle body (easy DIY, remove airbox, remove cable and remove 5 bolts and the throttle comes off) as its a MK1 then chances are it needs to be cleaned being 16+ years old- Take apart, clean and lube pedal assembly Although not having driven a drive by cable MK1 I can't comment on its characteristics although following the procedures above should help Link to comment Share on other sites More sharing options...
