Turner1990 Posted August 15, 2016 Share Posted August 15, 2016 Morning all, Im having a few problems with my 2000 WRX turbo after the weekend of fitting new parts, these parts include new knock sensor, new vapour canister, new crank shaft sensor, and new air filter. These parts where changed as there was a VERY SLIGHT miss fire when around the 3k rev mark but she pulled through well enough after a second or 2. However, since fitting all the new parts there is a major "cough and splutter" that happens when pulling away at low revs (e.g. when at rolling speed in 2nd gear she bounces and kicks like crazy) the only thing left i can think it could be would be the ignition coil pack itself (the plugs and leads are all new this year) but i am a bit reluctant to do this as brand new they are around £200-£250 and I've just had to spend £600 on a vet bill for the dog. has anyone else encounter this problem (the car not the dog) and what was done to fix it? Many Thanks, Turner. Quote Link to comment Share on other sites More sharing options...
stants Posted August 15, 2016 Share Posted August 15, 2016 Hello & welcome, have you reset the ecu? It will take the car a while to re learn the parameters as sensors have been changed Sent from my SM-G930F using Tapatalk Quote Link to comment Share on other sites More sharing options...
Turner1990 Posted August 15, 2016 Author Share Posted August 15, 2016 do you think it could be down to the MAF needing to be replaced? i gave it a clean out as it was covered in muck so its all shiny again now....? Quote Link to comment Share on other sites More sharing options...

Turner1990 Posted August 15, 2016 Author Share Posted August 15, 2016 update the air filter is an induction kit with a silver universal cone filter which only allows air in from the top end (not the sides) could it not be getting enough air intake? should i buy another which has the "mesh" going all round to allow more air flow or shouldn't that cause a problem? as i say it was riding lumpy before all the new bits where fitted but now its gotten even worse :( please someone help :( Quote Link to comment Share on other sites More sharing options...
Tidgy Posted August 15, 2016 Share Posted August 15, 2016 Get it to a specialist and let them have a look, could carry on chasing it round the engine bay and still not find it. Quote Link to comment Share on other sites More sharing options...

MJP02 Posted August 15, 2016 Share Posted August 15, 2016 if you kept the old bits I would swap them back 1 by 1 and see if 1 makes a distinct difference, cheapest way at the moment Quote Link to comment Share on other sites More sharing options...

Turner1990 Posted August 16, 2016 Author Share Posted August 16, 2016 Update: I swapped the vapour canisters back and swapped a one way vacuum pipe to facing the other way (and messed about with a few other bits and bobs) last night in the dark with a tiny torch that cuts out every 5mins (was not a fun evening at all) and hey presto its working so far.... so not sure if it was the canister or the pipe but either way I'm a happy choppy this morning :) Thanks for the advice people 1 Quote Link to comment Share on other sites More sharing options...
