Bought a new XJ this week, and the check engine is coming up misfire on all cylinders. Previous owner put on new plugs and wires. Im guessing the gap is wrong, and wires are going to the wrong spot on the distributer cap. Does anybody have a pic of the wires going to the correct spot? Its a 96 with inline 6. It drives find, just misfires the entire time and rough idle. Also has a small exhaust leak at the block from when they installed new exhaust manifold and didn't put on the gasket right. Could that have something to do with this? Thanks

Not a photo but this should help. Also yes the exhaust leak will make it run badly.

Thanks thats just what I needed. Yea hopefully I can fix the gasket soon, just sucks to pull everything off for one little spot where its bad

mrfajita

The gasket is like 24 bucks at NAPA but yeah those bottom manifold bolts are a pain in the ****.

If you're going to pull the manifolds off for the gasket, you might as well see if you can find a 99+ intake to put back on.

Last time I was at the andersens junkyard in Greeley there was 4 or 5 99+ Jeeps, two of the intakes were just laying on the ground. Mine from there was 26 bucks I think after tax.

I have a 99+ intake in my parts rig. Forgot about that upgrade Ill definately do that. How big of a responce did you notice?

Firing order is correct. Gonna go get a plug socket and see if there gapped right. Otherwise not sure what it could be

I believe you will find #1 goes at 5:00 viewed from the side.

Check to make sure the plugs are the ones called out on the underhood label - not what the parts house wants to sell you.

No BOSCH!

/Anybody know how to remove the plate under the distributer cap? There is a sensor there (camshaft position sensor?) Im trying to remove it, having difficulties. There is a bolt on the very bottom of it that is a huge PITA to reach, anybody done this before?

TPS will cause random multiple misfire.

Before anything - check to make sure the new plugs are the ones called out on the underhood label. They put the make, number, and gap there for a reason.
Parts houses will tell you to use ones that don't work but thy make the best profit on - the label doesn't care about profit, just how it runs.
