1999 Kia sportage loosing power under moderate acceleration.

1999 kia sportage lost power in mountains and would only pull up a mild grade. Also squeeling sound near alternator and smoke. Found squeel was not belts but leaking exhaust manifold, and smoke was from oil leaking from camshaft cover gasket. Towed it home to Nebraska and replaced both gaskets and plugs while I was in there. Also replaced both coils as they both showed signs of failing, although old spark plugs looked good. Previously had fault codes P301,302, and 304. Now all codes will clear and it idles pretty well and I can get it up to 50 mph after a mile or 2. But, if I crowd it, it makes a sound like Bwaah, looses power, and eventually sets the same codes. Fuel pump puts out over 50 psi going into a gauge that I put right after the pump, dead heading it. Fuel filter was replaced in 2008 and is hard to get to. O2 sensors seem to respond fairly normally as does fuel trim.

    Forgot to mention that I checked the timing belt and it looked great, but slightly loose.

    Additionally,, after it is warmed up I can get the engine up to 3,000 - 3,500 in park, but if I floor it I can still set the fault codes. I have a CP9180 diagnostic scanner but I don't have deep pockets. Thanks for any help.

    New cats and muffler 9 months ago, so they should have been good, but first cat appears to be collapsed and back pressuring. Runs fairly quite, but still rpm limiting, with only first cat in place ( warm up cat that is right after and close to the exhaust manifold ). Appointment Monday morning to have it checked out and, hopefully, replaced under warranty.

It sounds like a head gasket issue. Do a compression check to see if all cylinders are within specs. If you find there is an issue, decide if it is worth the repair cost. If you choose to repair it you will also want to check for an exhaust leak close to the engine such as flex pipe and also back pressure from a plugged converter. Otherwise you could end up blowing the head gasket again.

SOURCE: squeeling belt, have replaced idler pulley,

Try using a very small spray of silicone spray on the belt next time you're hearing the squeal. If it temporarily stops, replace the belt. Check the p/s fluid level, if it's low it could cause the pump to make noise. Also if it's low, you have a leak, check all lines, connections and pull back the bellows boots on the p/s rack (if rack and pinion). Finally, pick yourself up a mechanic's stethescope, good tool for diagnosing accesory noises. Listen to all components while duplicating the noise.

SOURCE: Can not start 2000 Kia Sportage with 161 K Miles.

It sounds like the timing is not set correctly. When you installed the timing belt, there are two dots on the crank shaft and cam shaft sprockets - these two dots need to line up as close to eachother as possible. This is done by putting the belt on the two sprockets while both dots face eachother - lay them down on a table or flat (clean) surface with both dots facing eachother (crank shaft sprocket dot should be facing up, and cam shaft sprocket dot should be facing down) - carefully insert the sprockets onto the cam shaft and crankshaft simultaneously - this usually takes some finess and patients - once they are in place and you are confident they are lined up, you can put the coverback on. Also, make sure (first) that the number one cylinder is at TDC (top dead center, or in the "up" position. Pull the #1 plug out, manually crank the engine over or "kick" the engine over with the ignition (have someone do it for you). You can use a small screwdriver,inserting into the plug hole (not all the way) and when you see it pop up, poke it in again to feel the piston is at it's maximum height (if you hold the screwdriver on the cylinder and feel the screwdriver / piston go down, bring it back up again.
With it at top dead center, and the two dots facing eachother, put everything back together. Make sure all gaskets are not "bulging" out of the cover. (if applicable) .
If this is all done correctly, the car should start with no problem.
Please let me know if you need further assistance.

SOURCE: Engine overheated because of radiator

5 minutes is a long time to drive a car with no coolant. Does the engine run rough, or miss? Or is it just sluggish and low on power? If it got hot enough, there could be permanent damage to the engine. Overheating can cook the engine oil into a gummy sludge and loses it;s lubricating properties.Check for signs of coolant in the oil. That would indicate a head gasket failure or a cracked head.

99 kia sportage sputtering under acceleration

Hi Missippirebe, I think you should replace the fuel filter and if the problem persists check fuel pump pressure. It should be at around 3.7 bar. Regards John

1999 kia sportage chassis acceleration sensor failed. I need the location and what it looks like.

The chassis acceleration sensor is located on the left side below the motor. Not on the motor but on a little metal plate connected to the body. I paid $55 at KIA for the part. The part # is 0K2NC-18911. They say it's a universal part. It took me two days to convince them the part even exist. But I have it now. I hope this helps.
