It is usally caused when the engine detects that the engine is in an unsafe condition that common sense. But its mostly caused in the v8 jags due to harness problems.Check the mass air flow sensor if u can see some open wires that can short to ground from the raditior brackets.Or the harness located on the front left side of the engine running downward. the harness usally shorts with groung from the topleft side due to improper installations from the mehanics....(kuwait)(Abu Ali)

00linc ls v8 240k miles little Skip off and on at times loosing water can't locate leek . could it be a head gasket going bad oil look OK not milky looking


Leaks are most common at hose connections, within the heater core, the radiator, or at the water pump. The water pump has a drain hole under the shaft that allows water to leak out when the bearing is getting bad. This is supposed to tell you to replace the pump. Unfortunately, many drivers fail to regularly inspect the engine compartment, and even when they do, often the coolant evaporated on the engine block leaving little or no residue to allow for detection. Seepage at hose connections can have the same results. The heater core leaking often runs out the firewall with the condensate from the A/C unit, so it is often missed. If you have no milky oil, then the head gasket isn't blown into the oil gallery. But you can have a head gasket blow directly into the cylinder(s) themselves. This will cause a white smoke from the tailpipe when running. Do not confuse this with the white smoke that comes with a early morning startup. This smoke is due to moisture that builds up in the muffler and is normal, but will stop after a few minutes. If the engine produces white smoke during normal driving under acceleration, then have it checked. You may be able to detect a slight smell of antifreeze from the tailpipe in this condition.

it could be many things, usually the throttle body will cause most of the fault displays your talking about.You need to get the car scanned to pinpoint the issue.

My 2005 Jag S-Type 6 cylinder check engine light came on and while in parked position the check engine light started to blink yellow and stated "Restricted Performance" what does that mean?


You have a fault condition in the the engine management system - get the codes read to indicate where the fault lies ... It is probably just a faulty sensor as this is the most common cause of check engine warnings. The restricted performance condition is meant to protect the engine or components from damage, so don't panic - get the codes read - its probably not as bad as you expect. hope this helps - good luck.

My 2204 jaguar s-type v6 with 115,000 miles has the amber engine fault icon on. The car is driving normal. What is causing the light to stay on all of asudden?


you may find this light comes on and then suddenly goes off again, This is caused by a monitoring alarm in the OBD II system that is sensing a fault as it carries out its constant series of checks on the engines performance during a set driving cycle. If the fault is not detected on the next driving cycle the light will go out. The most common reason for this particular fault is the MAF (mass air flow sensor) this can sometimes read out of range (due to dirt or sudden changes in air condition) Get the codes read as this fault will be logged in pending codes if the fault has disappeared or as a current fault if still displayed. Don't panic - just get the codes read !
hope this helps - good luck.

2001 jeep cherokee has a p1494 code and a p0301 code seems to be running fine but want pass emissions


0301 is cyclinder 1 miss fire,check coil pack and spark plug,plug first,1494 is the fan relay,It's in the right front of the engine compartment. Kind of behind and below the RF headlamp and in front of and below the fuse box.
Easy to replace, just unplug it and plug the new one in.
The relay is the most common cause for that code with a no fan operation condition, we see it all the time.
