Samantha1878 Posted March 21, 2013 Share Posted March 21, 2013 Driving home from work I realised whenever I was braking or completely stopped the n/a was still revving. When I was completely stopped In neutral handbrake on I watched the rev counter and it kept going up to 2k revs then down to 1k then back up to 2k. So I pressed the accelerator and took my foot of again and It carried on. So I pushed the accelerator up and it stopped doing it! It's Asif it was stuck or something! Is this something I need to be worried about :| ?? Quote Link to post Share on other sites
russ78 Posted March 21, 2013 Share Posted March 21, 2013 might be crap in your icv, when the revs come back down from 2k to 1k does it nearly stall ? Quote Link to post Share on other sites

The ones I've seen have an electronic valve on the bottom of the tb where the thermostat valve is on the GT and V tb. I would start by in hooking the throttle cable and making sure that slides in and out nice a freely. If that's ok I would move onto the getting the throttle body off and cleaning that out with carb cleaner Quote Link to post Share on other sites

Try unplugging the TPS and see if it makes a difference, if not it could be the TPS faulty Quote Link to post Share on other sites
Samantha1878 Posted March 21, 2013 Author Share Posted March 21, 2013 it does it as i'm braking and when i'm stationary :/ Quote Link to post Share on other sites
AdamB Posted March 21, 2013 Share Posted March 21, 2013 Try with the throttle cable first, it could be that as you've come off the accelerator and throttle is stuck open slightly due to the cable sticking Quote Link to post Share on other sites
rmsnoel Posted March 21, 2013 Share Posted March 21, 2013 Sticky throttle or throttle cable on top of foot pedal caught. Quote Link to post Share on other sites
