do you have any check engine lights on? If you do, that is the first thing I would have checked. It does sound like plugged EGR, vacuum leak, or bad TPS

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?

If yours is the v6 2.5 the tps is adjustable and you can turn it up and down. On my mazda it acted like it was in the fuel system and i ended up replacing the distributor.

Checking for spark is really simple while fuel delivery is more complicated because of the the way it is metered for delivery. On VW's a fuel pump relay is used and a jumper cable connected to relay box. This controls the fuel pump to deliver fuel manually. With a fuel pressure gauge connected to the line from the pump continued withing the system, you assess whether you have correct fuel pressure, maintain it within a specif duration. Electronic fuel injectors do stick or stay open causing very poor or no start condition. Make sure you have fuel delivery since you are positive that spark is present.
