SOURCE: truck runs rough

Sounds like one of your chambers isn't firing. Run your car for a few minutes, shut it off then pull your plugs one at a time and see if one of them is wet. Might just need a new plug.

SOURCE: check engine light on,idols rough,fine at all other speeds.

It either has a vacuum leak or a dirty MAF. To test for vac leaks spray the engine with carb cleaner to see if the engine speed changes., if it does you fond the leak. The most common leak is pcv line coming straight off the back of the throttle body. Check there first. Also check to make sure there are no air leaks between the throttle body and the mass air flow. Don't replace the idle speed motor or the tps, they won't fix it. It is possible the o2 is the problem, but it usually isn't. P0107 Is usually always from the stuff i listed above.

SOURCE: 2001 v6 escape rough idle when cold

To update my earlier repair on the 2001 6 cyl Escape: When cold, and when the ignition was turned over but no accelerator pressure given, the rough idle finally returned the P0303 code again when the check engine light came on indicating that it wasn't caused by the plugs or the coil. FYI, I had replaced the intake manifold gaskets during the original repair and just prior to that I had replaced the fuel filter which was very dirty (I cut it open to see).

The repair manual referred to fuel injectors as a possible problem. I have run three tanks of fuel using different injector cleaning products and am very pleased with the results. Cold starts are much smoother and I am unable to coax out the P0303 code or any other code.

My opinion, change the fuel filter, use a fuel injector cleaner for a couple of tanks, change the plugs if the problem still exists. The coils were not the problem on my vehicle.

2001 mazda tribute v6 runs rough cold ildes at about 200 rpm till it warms up then its ok what could it be


I replaced the upper & lower manifold runners seals, now it runs perfect, The reason it runs ok when warm is because the manifolds expand and seal the gaps on the surfaces that the worn old seals are not closing. Also change the spark plugs.

2001 MAZDA TRIBUTE COLD STARTING PROBLEM


My wifes car had this same problem at about 100000 miles and after many trips to the shop it turned out to be carbor build up in the intake manifold. A fuel injector cleaner was hooked up and it helped the problem, but did not completely solve it. In oreder to get it totally clean the intake had to be removed and clean it out manually.

Problems with cold engine


It is the head gasket. Have that replaced and you will be fine. You have an air leak. I was told by the mechanic at mazda that the anti freeze eats away at the gaskets. CRAZY, but it works. I still have an issue with my 2001 Tribute revving while in park. Its always something.
