Jaguar Repair: '84 XJ6 fuel pump noise, jaguar specialist, coolant temp
jaguar specialist, coolant temp, vacuum lines: The fine vibration is normal for the design of the pump.

Jaguar Repair: '84 XJ6 loss of power, vacuum leaks, vacuum gauge
vacuum leaks, vacuum gauge, coolant temp: Hi Michael, It sounds like you have several issues. It also sounds like the car has not been driven in a long time.

Jaguar Repair: cal screen vent, kick panel, rout
kick panel, rout, fresh air: Hi Jim, Fresh air enters the car at all times. The AC/Heat decides where to rout the air. There is no time that just fresh air is routed into the car without heat or AC. Only the Euro version brings fresh air into the car without heat or AC and that has nothing...

Jaguar Repair: catlitat comverter, r134, o2 sensor
r134, o2 sensor, freon: Hi Jim, The O2 sensor is before the first CAT so It would operate as normal. The O2 sensor is a minor adjustment to mixture. You should not use 134 in the Series III car, only use R-12 or any of the other gasses. I have used several of the Propane based...

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, vacuum tester, delivery problem
vacuum tester, delivery problem, fuel pressure: It is a waste of time guessing. Testing is the ONLY method to arrive at any conclusion.

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.

Generic CATs are only about $120. I would not expect...

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.
