View Full Version : 97 Disco Loosing Power

10-13-2007, 04:16 PM
Hello all, my 97 Disco is loosing power at Hwy speeds, never goes dead, just looses power for a few seconds. Changed plugs and wires and did not stop problem. This will happen for a few days and then not happen again for a few days or a month. I have previous owners papers he took to Dealership and they could not find problem.

Any help would be greatly appreciated!!!

97 Disco 125,000 miles

Kind regards,

I had a similar problem @ less than 60000 miles. I was told that it stems from a design flaw in that the exhaust ports were incorrectly sized and , when they accumulate enough carbon, it leads to intermittent misfires. I needed to have my heads machined. First step would be to wait until the next power loss and have your OBD checked.
