fixed idle now it shudders - Ford Forums

Well, fixed the idle problem... all i did was clean the IAC and the MAF sensor and now it idles fine. Now we've noticed that it likes to shutter lightly when your cruising. Not when your accelerating, just cruising at a constant speed or slowly declining in speed or slowly increasing...
only code was camshaft position sensor bank 1 came up. nothing else.
any idea?
Would this code cause this result?
thanks

It's very possible that will cause it. The PCM watches all the sensors and adjusts the mixture and timing from the readings.

would you know where that sensor is located?
...I'm assuming its a faulty sensor (or sensor related) rather than an issue with the camshaft.

these use timing CHAINS right? (V6)

thanks for your help...again

I found your previous post. These plugs go to the sensors. C643 and C1893.

those look fun to get to! you wouldn't happen to know which one is bank one would ya?

Bank 1 should be the side closest to the firewall. By the picture, it's hard to say. Look at the connectors and see which one goes toward that side.
