My car is still acting up. So now the car still idles like sh*t. So last night I go and start the car up and its starts acting funny. It stays at 2000 rpm and If you put the clutch in the rpms would go up. then starts idle surging. So i pull it in the garage and shut it and let it sit. So today I go out there and start it up and its warming up and the rpms are coming down and then it starts surging again so i shut it off and then start it again and it seems to be working fine. but it still surges alittle then when you rev it to say 5g let it go it will die. The isc is rebuilt and the throttle position sensor tested ok when the throttle body was rebuilt. I got a logger the yesterday and set the tps. I'm not sure what the hell could be causing this. My cas is leaking and it seems to be making a noise. So I was wanting to know if the cas could be causing this?
