ddcboyle Posted May 26, 2013 Share Posted May 26, 2013 Hey, okay so i have multiple problems that have just happened recently but cant put it down to anything. Problems are (and im not sure if their linked with one another) 1- I have an engine managment light showing. It has been showing for a month or two, and my diagnostics checker says its the cat pipes. I got a brand new invidia exhaust, but its still showing. 2- Theres a knocking noise when i go over any form of bump in the road. Its coming from centre console forward, it sounds like an engine part is loose, i wouldnt imagine it to be the exhaust as it was fitted pretty well. 3- This is the main issue, when i put my foot down in the car, the revs go up, back down, and then the car revs normally. the only example i can give is, its like when your wheel spins, the revs go up but car isnt going any faster. This now happens even if im doing 60mph and just put foot down a little, rev up, rev down and then it gains speed. The only things that are going through my mind which it could possibly be are, - my air filter needs cleaned (its k&n typhoon and havent cleaned for around a year) but then i dont think that would cause the problems, but i could be wrong. -Or, its something loose in the engine/exhaust area, i thought it could be my manifold, and that would explain the knocking, the engine management light and the revs going a bit haywire. Im going to be taking it to a garage this week or the following when i have spare time. So any ideas before hand would be good so i could possibly have an idea of what to expect.

The Chubby Ninja Posted May 26, 2013 Share Posted May 26, 2013 Maybe your clutch slipping? That would explain the wheelspin like symptoms 1 Quote Link to comment Share on other sites More sharing options...
Sam Mcgoo Posted May 26, 2013 Share Posted May 26, 2013 No. 3 = worn clutch. Need a new one. Quote Link to comment Share on other sites More sharing options...
lmc Posted May 26, 2013 Share Posted May 26, 2013 No 2 possibly drop links Quote Link to comment Share on other sites More sharing options...
Sam Mcgoo Posted May 26, 2013 Share Posted May 26, 2013 No. 1, have you reset the light? Do you have decats, high flow cats or standard cats? Invidia exhaust is cat back, it shouldn't effect it but increased flow may have contributed to a cat warning. No 2= get under there and have a look, shake, feel, poke and bang. No. 3 = worn clutch. Need a new one. Quote Link to comment Share on other sites More sharing options...

370Ad Posted May 26, 2013 Share Posted May 26, 2013 Tootle along at 30mph in 6th then put your foot to the floor. If the revs rise rapidly then you need a new clutch! Quote Link to comment Share on other sites More sharing options...

rtbiscuit Posted May 26, 2013 Share Posted May 26, 2013 Cats don't come with exhaust.... so I'm guessing its stock cats. In that case it could well need a new O2 sensor. What was the engine code you had? Quote Link to comment Share on other sites More sharing options...

Ekona Posted May 27, 2013 Share Posted May 27, 2013 If you're doing the clutch, do the lightened flywheel too. It's a no brainer, it really is. Quote Link to comment Share on other sites More sharing options...
ddcboyle Posted May 27, 2013 Author Share Posted May 27, 2013 money money money... Was planning to sell the car after next years insurance, but just spend 850 on exhaust and now <1grand for clutch. If i hadnt bought the exhaust i think i might have just sold it after hearing this Quote Link to comment Share on other sites More sharing options...
