I had a bad misfire it turned out to be the wires but I had the intake manifold off several times the misfire is cleared up. Now I have two codes I had checked P1505 and P1507. Idle speed control valve. Found it check the connection The connection is good but I was wondering if I could just take off the sensor and the control and clean it? I see if it was bumped around a bit the valve getting stuck. Any suggestions before I change it? Or if I should change it?

Good afternoon,

Since it got bumped around, I would just replace the motor. Most likely it is damaged internally. You cannot clean them. The area that gets carboned up. you cannot access it. Check out the images (Below). Please let us know what happens.

It was just the connection. The connection was loose I took it off put it back on and it was working fine.But, my crankshaft positioning sensor went again. Check engine lights on again car will not go over 3,000 RPM's luckily when I bought the wires I bought the sensor again. This is the second center in like two years. Can any of this that is been going on below the center?

Did you replace the sensor again? Make sure the surface is clean of all debris. If there is any dirt on the mounting, it will not sit correctly.
