Generally this happens because these codes were reset at a dealership etc. These problems should have been corrected before the codes were reset (reputable dealer). A common reason that these codes come on is because of excess hydrocarbon emmissions with a misfire. If this was a temporary event, the light would reset. Since it continues, another likely reason is the oxygen sensor in the exhaust system has failed.

SOURCE: Mercury Cougar 1999 V6 Starting problem.

To remove the alternator, you have to remove the serpentine belt. They have a tensioner in which you place a socket wrench and pull on it and it loosens the belt. Before removing the belt notice how it is routed. Some vehicles have a diagram on the hood or on the front near the grill.You take the belt off. Then you remove the alternator by removing the bolts attaching the alternator to the engine. There are two or three bolts you have to remove. Two of them are fairly big bolts. About a size 14 metric or so. Disconnect the negative battery cable battery so you won't hit any grounds.Then take off the plugs from the alternator and the small nuts that hold the wires. Notice how they are placed before removing so you can know where each plug goes.Then replace the new alternator. Plug it back up and install the same way you took it out.Replace the belt starting from the left to right and pull on the tensioner and reinstall.

SOURCE: LS430 check VSC light on after check engine light on

My car (06 GS430) began giving me more frequent "Check VSC" warnings. (Code P0455 in my case. Really glad I bought that OBDII tool--resetting the codes is a snap!)

I knew that a loose gas cap could cause this, so normally I just give it a twist and it tightens. Now I found that no matter how many "clicks" I tightened the gas cap, it would not cinch down snug. The lightest turn the opposite way would open it.

I was all set to head over to CarQuest for a replacement filler cap. But I thought I'd inspect mine first just to see why it stopped holding. Upon inspection, I saw that what holds the cap in place is compression of the rubber O-ring at the back of the cap, which compresses against the filler neck. That apparently was no longer happening.

I carefully removed the O-ring from the cap--using screwdrivers to lift it over the edge of the groove it sits in. Like removing a bike tire from the rim--work your way around. Then I cut a strip of electrical tape about 10" long, and 1/4" wide. I wound this into the curved groove where the O-ring normally sits, just to build up a little thickness. Put the O-ring back in place. Done.

Now the cap tightens like it's supposed to, and thus far, it has stopped the VSC error codes. Don't know if it will fix your issue or not, Good luck.

Are there any Isuzu dealers in America anymore? I thought they all left. If you have one still, go to it.

SOURCE: How do I fix imrc on the 2002 mercury cougar p1519

a p1519 means your intake manifold runner control is closed on bank one (where #1 cylinder is located)-check to see if the hose that goes from the solenoid is disconnected, or damaged, and if it has a wiring harness (some have both) check to see if it is connected and the harness and connector are not damaged. You should be able to manually open the butterflys, and if they are stuck shut this might be enough for you to get them working again. To clean them (they get gunked up) you need to remove the intake and use a throttle body cleaner to clean the bores and plates up. Consider the possiblilty that the solenoid's vacuum diaphram is damaged-hook up a long enough hose to the vacuum port and **** on the end, observing the solenoid arm-if it does not even try to move, you need to replace the solenoid.

Can you bleed the water cooling system on 1999 mercury cougar


This is extremely important on some cars, for instance my BMW. 1. Have the car parked in a slight uphill slope. Make sure there is enough coolant in the expansion jar.
2. Start the engine and wait for the thermostat to open (upper radiator hose becomes warm).
3. Open up the radiator bleeding nipples slightly with a large screwdriver (bleeding nipples normally made of plastic with a '+* for a screwdriver to fit, at the highest points in the cooling circuit).
4. Allow air bubbles to fizzle out until you get a steady stream of coolant leaking out, use rags to capture leaking coolant.
5. Then close the bleeding nipples, switch off the engine and wait a few minutes for pressure to come down.
6. Open up the cap on the expansion vessel carefully and fill just below the "hot" marking.
7. Check levels again after a few miles and refill further if needed.

Done.
