The fuel sensor in my 1998 jeep cherokee is moving up and down

you need to check all sensor connections as the crank shaft sensor also will mess up your idle....try slightly unscrewing the tps and push it up or down slightly to see if this fixes the problem.

6 or 8 cylinder? Either way the computer (ECM) controls the coils. 6 cyl has a 'coil rail' and 8 cyl had individual coils on each cylinder. There are crankshaft and camshaft sensors that tell the ecm when to fire each cylinder

On my dodge truck, it was the throttle position sensor that went bad. It is located on the side of the throttle body. $50 for a new one, or $100 to have a shop do it.

Hope this helps (remember to rate this answer).

4.7L ENGINE CRANKSHAFT SENSOR LOCATED ON THE ENGINE BLOCK ABOVE THE STARTER. ON THE 4.0L ENGINE CRANKSHAFT SENSOR LOCATED TRANSMISSION BELL HOUSING AT THE LEFT REAR OF THE ENGINE. THE 5.2L 5.9L CRANKSHAFT SENSOR LOCATED ON THE ENGINE BLOCK BEHIND THE RIGHT CYLINDER HEAD.

The fuel filter sits on top of the fuel pump. It is the fuel fuel filter/fuel pressure regulator. You will have to drop the gas tank to access it. Hope this helps.

Best of luck
