Are you in the market for a Ford? Check if it's equipped with IMRC (Intake Manifold Runner Control). If the answer is yes then you can factor in the repair cost straight away because it's bound to be broken. It's not a very expensive fix (the mechanism looks a lot like cruise control) and Ford owner forums provide tips on how to do it yourself. Be warned that it may not be easy to detect a defect by yourself!

DUDE! I just bought a 2002 Focus SVT back in April. I barely made it off the lot before a check engine light popped on telling me there was something wrong with the IMRC. I ended up blasting sea foam through it and adding some other shit to my gas tank. Voila problem solved. Only to be replaced with a check engine light pertaining to my high flow CAT not working.

I remember that V6 Ford/Mercury Cougars had a massive problems with IMRC. It was stupidly placed and would often overheat and burn out a transistor. What's more, no warning light would light up. A field test devised by the owners' club was to invite a friend with a 2 litre Cougar (those were IMRC free) and race him. If you lost - your IMRC was broken.

That is a ridiculous test. See my issue is, since I bought this fahking car I have had a check engine light on. first for the P1518 code, then a code because of the tune that is installed on it, then most recently a P0420 (or maybe P0402) which has to do with the CAT. I owned 3 different hondas over 7 years and never had ANY problems with any of them. So far I have had 5 problems with this ford in the first 5 months of ownership.

My parents owned a 2003 Focus for 6 years and the only problem they had was a burnt out ignition coil and a cat failure that resulted from it. All that got fixed under warranty.
And the IMRC test story was more of an anecdote than anything serious.

I didn't have any trouble with the IMRC on my Gen 2 or 3 Taurus SHOs, but I've read that many others have. Do you recommend repair or just wiring them open?

If you want to properly take care of your car it's always better to fix it. Locking the valve in the "open" position can cause problems with idle, increase fuel consumption and slow the car down on low revs, much like the valve staying closed impedes high rev performance. If you don't care about the car you may as well leave it be. Many models don't even bring up the check engine light if IMRC breaks.
What I've seen some people do on Cougars and quick Mondeos was move the transistor (or the whole mechanism that operates the cable) to a different spot in the engine bay or put some additional cooling in there.
