What is a p2098 on a 2005 jeep grand

Do you have a check engine light on and flashing? Have you run the OBD2 fault code test?

2008 jeep cherokee (hemi) engine light its on i brought to fix they change 4 sensor and the converter. After 5 days engine light comes on again, what else can be? im depress about it, after paying almost 2 grand to fix this issue.

The 6 cyl engine uses a coil strip for all 6 cylinders, and the 8 cyl uses one coil per cylinder. So I assume you have an 8 cyl engine.
You are saying one coil has power but is not firing ?
Have you switched it with another cylinder to eliminate the coil as a possible problem ?

Hi Joko,

What you are describing is a failure of a main circuit. The first thing you should check is yo make sure that your battery is in good condition and that the cables are clean and tight. Let me know if yu find anything wrong there. Then there may be another main circuit problem. Check all of the fuses in your fuse block in the engine compartment. If any of these fuses are blown, it will usually cause several things to not work. If you find any fuses blown, DON'T REPLACE IT YET. Let me know WHICH fuse is blown and I can help you find out why it blew so you can get the problem fixed.

Get back to me on this and we will continue.

6 CYLINDER IS A INLINE ENGINE LONGER ENGINEIT HAS SIX SPARK PLUGS. THE V8 ENGINE HAS 2 VALVE COVERS. LEFT BANK RIGHT BANK IT HAS 8 SPARK PLUGS..

When was the last time spark plugs were installed??? How many miles are on the vehicle and is there a check engine light on?

It maybe a loose heatsheild on the manifold, converter, or underbody heatsheild.

If the light is ywllow, it's emmissions or some sensor. You can drive to a service center and have the codes read. If the light is red...STOP!! and check engine oil. DO NOT drive further!! Have it towed in for service.

Check intake gasket and vecuum hoses near intake runner #4. To do this spray carb cleaner at parting line between manifold and block while engine is running. If leaking rpm will dramatically change. A leak will lean out that cyl and cause misfire

You say you changed the cam sensor. A1391 code is a crank sensor on the top of the trans. bell housing.
