Re: troublesome idle, Scorpio 95
Check your vacuum hoses to carby especially the idle control valve. If you've moved the motor to get access, which if its front wheel drive you will have, you may have put the vaccum hoses on the wrong part of manifold eg lower or higher vacuum than necessary casuing actuating valves to either stay open when they should be shut or vice versa or a hose may be off which causes the engine to loose vaccuum and stall. Hope that helps
If You always do what you've always done, you'll always get what youv'e always got.
