Engine problems check engine is on, sometimes when I try to accelerate, engine do not work. . Now, if you disconnect the idle solenoid valve, the fault disappears, so I changed it, but the failure continued. If you keep the idle solenoid valve connected , and you disconnect the TPS failure also disappears, but the engine ralenti over 1000 RRPM ... Where can I find the values / Ohms ??to check if the TPS is bad or if some other sensor that the problem ... Currently, I removed the idle solenoid valve minimum and adjusted manually the screw, it works fine. The only problem, cold start I appreciate all the help. regards

Good source for Kia its free to register NO STRINGS

SOURCE: car won,t start sometimes & check engine light

before changing any more parts there are grounds on the engine that need cleaned one on the back of intake manifold then you have to remove battery tray clean up the ground there then clean where the tray bolts up as this aids in chassis grounding remove ground cable from bellhousing before you reassemble install star washers btween cable ends and where they bolt up this will dig into ground surface and cables making a better ground then remove turn signals in front there are two on right side and one on left side cleanup and star washer then there is the ground spots for the ecm inside removr kick panel on right side clean up and star washer if the starter doesnt work after this starter is probably bad but the other codes will probably clear out

I have 2005 Kia Sportage with a check engine light. No other symptoms. I was told by Kia and Local mechanic that it is the fuel injectors. Error Code states that Fuel injectors are running lean. Put Master airflow- no change. Ran engine test with propane to run rich and trim never changed from 15. Car runs great. Kia dealer said that this is because we use Ethel in gas that it effects the alumium fuel rail delivery to the injectors and that it is necessary to change all of them .Kia Dealer wants $1,000.00 deposit to place order 6 fuel injectors from Kia. (Has anyone heard of that?)Also put fuel injector cleaner in tank.Does anyone have any suggestions before I spend over $1,000.00 to replace all 6 injectors or possible idea of what could be wrong?

Well, it is either a timing belt/chain going out or a bad crank position sensor most likely causing the other problems. The O2 sensor may be bad as well but that usually doesn't cause the Misfire. The vehicle on board computer is confused, that is why it is throwing all those codes. and why it gives you that 1166 code which isn't defined. Check the crank position sensor and the timing and timing belt first. Once you have that fixed the rest should clear up.
