Eng cuts out at steady speed under light throtle
i have a 1990 xj6 the head gasket blew between the #5 and the #6 cyl. I replaced the head gasket and all gaskets when it started all was fine. when I took it for a test drive at about 1/3 throtle an about 50 mph it has a miss. Let up of the gas and it is fine. Step on the gas and it runs great. The code that is showing is a 26. 02sensor / Leak. I can find no vacuum leaks. Does anyone have any info on this. I really need some help on this. Thanks John.

As you had head gasket problems with #5 & 6 you might have a plugged up catalitic converter (the ones that are in the manifolds plug up then forces the ehaust back up the manifold which creates heat and slugish engine responce). I had similar problems and resurfaced head twice before finding the problem was caused by the cats (i just punched the guts out of them and put them back and the emissions still checked out ok I guess the ones in the pipes worked). The best way to check is put the car on a lift remove the manifolds from the exhaust pipes,start it up and see if there is equal flow out of the manifolds.
