2000 XK8 Intake Manifold question
#1
![Default](/forum/images/icons/icon1.gif)
Hi All,
On my 2000 XK8 Convertible with 67,000 miles, after replacing my intake manifold in November with a used one (my mechanic said it leaked like swiss cheese), I continue to get more than occasional P1316 excessive misfire and P0302 Cylinder 2 misfire.
Replaced Spark Plug and Ignition Coil two times with no change. It usually seems to happen at lower RPMs. Bad stuttering near 2000 RPM. I was reading about adding K-Seal to cooling system to Repair
possible small cracks in the intake manifold. I don't see any coolant leaks at all. It may run fine for three or four days, then terrible for several days. Any ideas from anyone would be appreciated.
Much thanks,
Eric "erjent" Jordan

I've been through this, it's like a whack-a-mole game! I had my intake pipe off and for life of me, couldn't see any cracks. Finally took it to a local shop who did a smoke test and sure enough, it was indeed leaking in the accordion section. Although pricey, I wanted to keep the car original and the shop was able to source a new old stock intake pipe.
