#25 of 67 2001 Kia Sportage
Jul 09, 2008 (2:35 pm)
My 2001 sportage is misfiring and running poorly on and off. the check engine light is on and code says random misfire on # 3 and 4. sometimes will run okay, then will surge (suddenly have power again) or sometimes all but die and start to back-fire (engine light starts to blink on and off about then). Have replaced plugs, both coil packs and plug wires. had timing belt changed within last two years, less then 30k miles since. total miles is 114K. problem is worse w/ A/C on and/or under load. Dealer told me today that he can't tell me anything else without a few hundred $ on tests.
Any ideas? You can contact me direct at jon1099hotmail.com

ALl symptoms definitely show spark problem.. Very sensitive to humidity...train hair dryer over coils and plug wires. Also, oil intrusion from cam/valve cover gasket is a common problem and can contaminate spark plugs starting with #4...then 3....I would open the valve cover (more annoying than difficult) and check that out....

I have replaced plus, wires and coils at same time and no better, so not humidity. problem always gets worse under load, uphill or with AC on. Tending to think timing belt off a tooth, but acts more electrical.
Any other ideas.
thanks for the input

how do you line up timing marks on the 2.0, and how do get the belt around the lower pully

Not done yet on mine...to come soon...but read these instructions... lower cover seems to be still there on photo above, but obviously, it must me taken off since crank balancer needs to be removed as per instructions...when I do mine, I'll take photos...but if you can take pictures, it might also help others....and myself...

... indeed I'd check T_belt, as imprperly timed valves caould let exhaust from one cyinder stray into another and cause backfires and this would show more under load....but no garantee. The idea is to clear the option so one can look at other things without the possibility of this cause still hanging over your head. Your findings can be very helpfull for others...so keep us posted.

what happened was the crankshaft pully bolt loosened up and the pully came forward and pulled all the belts off with it, it messed up the timing blt but did not break it, now im trying to get the pully all the way off and clean it up to put it back on.
#32 of 67 Kia Sportage 2002 temp gauge drops car slows

I'll be driving when my temp gauge drops to C and the car slows down, I've noticed rust in the radiator when I remove the cap, if I flush the radiator will that solve the problem? Maaer
Also where is the drain plug for the radiator is there a diagram? Thanks All

I have a 1997 Sportage that does the same thing. I took it to the parts store where they ran the codes and said it was my mass air flow sensor. They said that the misfires and backfires are from the air to idle ratio, and that it can cause major issues if it isn't fixed... Soon!! Car doesn't idle well, when a/c is on it almost shut off, and it goes extremely slow when going up hill. It costs about $160, pretty expensive, but it will save on trying to replace everything else just to find that it was that all along. I would try that before you change anything else.

Good idea, I hate to drop that kind of cash on a maybe, but a good direction to go.
