Jaguar Repair: moldings, loose body, rocker panels
loose body, rocker panels, moldings: Hi Jim, Jaguar did not come with chrome strips on the rocker panels so I have no clue how to get them loose. Body shops have to contend with aftermarket add-on strips so you might let a body shop look at them and maybe advise you the best way to remove them...

Jaguar Repair: Re: 1986 XJ6 dies after running, spark plug wire, noid light
spark plug wire, noid light, auto parts store: OK, the 20 PSI is useless info as when the engine dies the flap in the airflow meter closes and that turns the pump off.

Jaguar Repair: 1984 SeriesIII Federal wont drive when warm, mate brad, u bolt
mate brad, u bolt, limp home: Hi Brad, My guess is that the injectors needed work because of the rust in the fuel had got past the fuel filter and may still be a problem. When you have a running problem you MUST be able to see fire (spark) and Fuel. Did you run a compression test?...

metal pipes, sorry jerry, pipe connections: Sorry Jerry, I have never put one in an S but have in the 85 XJ-6 and I am guessing it may be the same.

Jaguar Repair: 1986 XJ6 Engine Tapping Noise, piston speed, oil viscosities
piston speed, oil viscosities, valve action: Hi Jim, By tapping I take it that it is a light noise.

Jaguar Repair: my 83 jaguar xj6 is sputtering when you step on the gas petal., fuel pressure regulator, jaguar xj6
fuel pressure regulator, jaguar xj6, vacuum hose: Hi Edward, Your symptom narrows the problem to about a thousand things. You do need to drain the tanks and flush them.

Jaguar Repair: '84 XJ6 ball joints, caliper pistons, caliper piston
caliper pistons, caliper piston, piston seals: Yes, but look closely for any leaks and watch fluid level. One more thing to check.

Jaguar Repair: '84 XJ6 ball joints, lower ball joints, spindle assembly
lower ball joints, spindle assembly, air hammer: Hi Michael, That ball can be a tough one because of the mild angle on the tapered shaft.

Jaguar Repair: '84 XJ6 loss of power, continued, tank leaks, vacuum test
tank leaks, vacuum test, vacuum line: If you had that much rust in the tank, your fuel filter has to be partially clogged. Vacuum line T can go on any of the vacuum hoses. A T on the fuel line is easiest at the fuel line just before the fuel rail. Leave the regulator alone. Howar...

Jaguar Repair: '84 XJ6 loss of power, continued - NOW A/C, compressor clutch, compressor side

Jaguar Repair: '84 XJ6 loss of power, continued, fuel pressure gauge, air flow meter
fuel pressure gauge, air flow meter, vacuum gauge: Hi Michael, When the vacuum goes to zero that is a indication of a stopped up exhaust system.

Jaguar Repair: '84 XJ6 loss of power, continued, fuel pressure regulator, quick snap
fuel pressure regulator, quick snap, necessary modifications: The high RPM and high load is what you need to look at for back pressure as opposed to a quick throttle movement.
