The codes P2112 and P2104 are in most cases caused by a eaither the connection to the throttle body motor and or a bad throttle body motor itself. I would start with making sure the connector is clean and tight and if so then you are likely going to have to replace the throttle body assembly. In most case its the throttle body assembly as the motor is not serviced separate.
I was planning on replacing the motor over the weekend It doesn't look like it would be very hard. I was going to replace the throttle body gasket to rule out any vacuum leak at the throttle body and give it a really good cleaning cause its really dirty.
I replaced the throttle body motor and gasket cleaned the throttle body and I'm left with the lean codes still. Dose run nice though. Changed the oil and fuel filter. I get between 38 psi and 40 psi fuel pressure. I live in south jersey. What should my BARO, MAF, throttle position, vacuum and timing be at idle if anyone knows?
I am also having trouble with a P0174 Code and am seeking advice. First off, I did a no-no and washed my engine. I've done it before but always drove immediately after to dry things out. This time it sat for about an hour before a quick trip for breakfast. Next day and the past few days its been idling rough and feels like it missing on a cylinder or two. The only code I get is P0174 System Too Lean (Bank 2). Wouldn't I gets code for both banks being lean if I had a vacuum leak or MAF issue? I did check the MAF and cleaned it with electrical cleaner. Also checked the first couple of COP to see if water had filled the spark plug hole but all I found in there was dielectric grease. I not getting any codes for misfires. I've checked all the vacuum lines and fittings I can reach and all seem to be fine. I'm rally at a loss now. I'd hoped that if moisture had gotten into something it would have dissipated by now several days later she's still running like crap.
Well i had that code then I ended up with both. My intake gaskets went bad and i had a vacuum leak in the intake. I replaced the intake and gaskets and haven't had a problem since. I took it to ford and paid the 100 bucks and got a definitive answer. I bought both ( intake and gaskets) from ebay for 320 total
