Having problems with your Kia Sportage ?

99 kia sportage, backfiring, no power, rough idle.

\015 I have a 99 kia sportage, which is backfiring, and lost all power, and has horrible idle. A few weeks back it overheated, and leaked out nearly ALL the coolant from the system (separate issue obviously). I filled the coolant tank again, and was fine. Shortly after, I decided to put in a fuel injector cleaner, as it had a TAD rough idle, but full power and no backfiring. Within an hour of putting the treatment in, the car was in BAD shape. It literally has NO power at all now, revs extremely high trying to climb tiny hills, and backfires about every 1-2 seconds, at low and high acceleration. I was originally thinking bad fuel filter, as all the gunk from the injectors might have plugged it. Replaced it, which made it run 10% better for a day, but didn't fix the issue. I grabbed a set of plugs, as I thought possibly the overheat might have fouled a plug or 2, but haven't yet swapped them out. I know vacuum leaks are the main cause of these sort of issues, and I also noticed a bit of fluid leaking from the head, and a bit of coolant smell through the vents occasionally. At idle it doesn't backfire much, or at all, just under any kind of load. From the info I can gather, most folks seem to think a head gasket leak wouldn't be substantial enough to cause all these issues, even if it WERE on the way out, but thought I'd get some more opinions. Also, the backfiring seems to be coming from the front of the vehicle, as I can physically feel it under my feet while driving - and it's LOUD as hell! Plugs? Head gasket? Sensor? Exhaust manifold leak? Any help would be appreciated - thanks!\015 Posted / edited by AnonymousUser on : 22-01-2018

My 1998 KIA Sportage backfires a little and doesn't have any power off the line. When I get up to speed and while idling it runs fine. The engine light is on and the code indicates that the number 4 cylinder isn't firing properly. I changed the plugs, wires, and fuel filter but it didn't help. The timing belt was replaced 30,000 miles ago. There is also a light on the dash that says "hold". It has something to do with the auto-transmission. The only other thing I could think of would be the fuel

2007 kia Rio Engine shuts off intermittently. History: 1 year ago we had an issue with rough engine and power issues (Approx 150k). replaced spark plugs and same issue. Engine light codes reported misfire on cylinder 3&4. replaced both coil packs for those cylinders and no problems since. Then out of the blue a couple of months ago the engine would just shut off randomly, no bogging or rough idle, just the engine would stop running. this would happen usually when slowing to a stop, making a slow

For a 1989 Corvette L98, basically stock. Hard to start, particularly when hot, might die once after catching momentarily. Always have smell of gasoline after starting, exhaust pipe black and sooty, but emits no black smoke when starting or accelerating. Idles really rough, but drives ok on the road at any speed, good acceleration and power, not rough at all. Will backfire when getting off of the acceletrator especially at higher speeds. Have already replaced all injectors because supposedly

Hi, I have a 2000 kia sportage ex standard which I purchased last spring. Lately it has started to lose power when you go to take off. It idles fine until you start to drive. This has happened about 4 times since Christmas. It loses power even in first gear. I've had to pull off to the side of the highway to try and get it to rev up. I've noticed this happens when you stop the motor and start it again. My second problem is the temperature guage doesn't go up. It is winter here and not having hea

Intermittent problem. Truck ran fine one day and barely ran the next time I started it. Runs incredibly rough like it's missing but not like a consistently missfiring plug but missfiring on all plugs and won't idle without quiting. When I open up the throttle wide I get power on all cylinders momentarily and then the same thing, coughing spluttering and occasionaly backfiring.... Then for no reason it will run well and idle well and I can drive it normally.
