Engine Performance problem
1994 Jaguar XJ6 6 cyl Two Wheel Drive Automatic 82000 miles
1994 Jaguar XJ6. The other day would not start but will turn over fine. Towed car home and tested for fuel OK, Spark OK. When turning car over it fires as you just release the key. I depressed accelerator 1/2 and tried to start which it did as I let go of the key. It ran for 10 minutes then while goosing the throttle it stammered and stalled. Will not restart but still will fire as you let off the key.
Checked coil for carbon track- negative. TPS checks out with voltmeter and voltage to MAFS is OK on battery power side and feed from ecm. The car has no codes stored in the VCM. HELP
