Since I got it there has been a constant rough idle and slight miss no matter what temp. I have replaced spark plugs, coils, cleaned the throttle body and checked as best as I can for air leaks. So far I have not been able to fix the problem. I have reset the ECU, reset the VCT, changed the fuel and air filter. Really starting to run out of ideas.Does anybody know anything more I can try? It doesn't break down under load, in fact it goes quite nicely when I accelerate or cruise. Kinda stumped.RegardsNick Link to comment Share on other sites More sharing options...

Are the mounts filled with fluid or something? Link to comment Share on other sites More sharing options...

Did coils, plugs, cleaned TB and everything all no less than 15,000km's ago. I've done everything you have as well... My needle does bounce as well... Sometimes when she idles after a drive she feels like she's gonna bottom out. (Is you car, by chance an absolute pig to drive when she's cold? )I hope for both our sakes that it is the TPS - I'll be following this thread closely Can we check the TPS ourselves or do we need to take it into a shop?Mine still goes like a bat out of hell, but these other drama's are annoying me...Good luck mate Link to comment Share on other sites More sharing options...
