Small problem
My '94 Lincoln with the DOHC 4.6 will hardly run first thing in the morning. It idles rough and when I put it in gear it bucks and sputters and you have to really mash on the gas to get it to move. Once it gets moving it drives fine and never does it again all day. Only does it first thing in the morning. Any ideas?

Re: Small problem
Well it kinda sounds like a vacuum leak or possibly the IMRC's are stuck open. I've really never heard of the IMRC's sticking in the open position but it is possible. Have you tried cleaning your maf?

I ran some Seafoam through the engine a few weeks ago. Do you think another can would be good as well? Mike Donley

Re: Small problem
I guess it couldn't hurt to run another can through. Can you feel your IMRC's open when the car is cold? I know when I first take off in my car I can feel the carslightly bog when the IMRC's open, wasn't sure if it was the same in your car.

Re: Small problem
Well my car has an electric motor that opens the IMRC's so I can just rev the car to 3200rpm and feel the cables at the back of the intake open the IMRC's. I think your is vacuum operated so I'm not sure at what RPM or vacuum they open at but you should be able to see or atleast feel where the cables are at the back of the intake, then try reving the car up to see if they move.
