ibs 308 Posted July 22, 2015 Report Share Posted July 22, 2015 So when I plant my foot fully down on the accelerator pedal after changing gear the car momentarily jerks a few times and then starts moving again. I thought it may have been it not getting enough fuel as I was running the standard pump. But today I had a performance fuel pump fitted and it is still doing the same thing. I was going to try an injector cleaner tomorrow in case one of the injectors is blocked. Is there anything else I should have a look at?Thanks Link to post Share on other sites
dave_424 48 Posted July 22, 2015 Report Share Posted July 22, 2015 Do you have a diverter valve or blow off valve? if you have a diverter valve, do you have it recirculating back into the turbo inlet after the MAF? Link to post Share on other sites

I'm not to sure wether it's doing its job or not though as I'm not sure if it's set up right and I don't know how I would test it. Link to post Share on other sites
FishWick 21 Posted July 24, 2015 Report Share Posted July 24, 2015 Sounds like it's either going lean or could spark issues. Have you got an AFR gauge in the car? Link to post Share on other sites
ibs 308 Posted July 24, 2015 Author Report Share Posted July 24, 2015 I've not got AFR fitted. A couple of days a go a mate told me to try some injector cleaner I've put some in and that has made a slight difference. It's not doing it as bad as it was so I'm going to try another bottle with my next tank of fuel and see what happens. Bealieboy 1 Link to post Share on other sites
Bealieboy 1,625 Posted July 24, 2015 Report Share Posted July 24, 2015 What cleaner did you use ibs? Link to post Share on other sites
dave_424 48 Posted July 24, 2015 Report Share Posted July 24, 2015 It isn't detecting knock on gear changes (heard it happening on some EVO's and subarus) and retarding your ignition timing is it? can you check knock count using VCDS? Link to post Share on other sites
ibs 308 Posted July 24, 2015 Author Report Share Posted July 24, 2015 What cleaner did you use ibs?It was the Forte stuff bealieboy. My mate had a bottle in his garage so he gave it to me. Bealieboy 1 Link to post Share on other sites

Will give that a go if the second bottle of injector cleaner doesn't do the trick. Bealieboy 1 Link to post Share on other sites
