My Comanche has been taking loner and longer to start it seems. It also will idle great for about the first minute after you start it cold. But then, as the engine warms up the idle drops and gets more rough. Then at about 170F the idle jumps back up and seems to idle ok. When the engine is hot though, the idle is at about 800RPM and every 10 seconds or so there is a rough period in the idle that shakes the whole jeep. The idle speed is also very erratic, fluctuating +-200rpm. I've compeltely removed the throttle body and cleaned everything, check the intake manifold bolts, and checked for vacuume leaks.
Today I disconnected the Camshaft sesnor at the distributor, started it up and it took about the same length of time to start. I also disconected it while the engine was running and nothing happened. I'm thinking the Sync sensor is shot.
Anybody replaced this sensor before? I'm assuming I have to remove the distributor? Can I replace the sensor without messing up the timing of the engine?
