so i have cleared the codes with a code reader and the way you have stated after replacing all 3 parts. the sportage don't want to start again until the cel pops back on then it runs great with the light on and will start no problem. the parts are new and the light comes back on after being cleared. wouldn't that make it the ecu? also because of this i think it is running extreamly rich (can smell execs fuel)

The ECU is a very robust piece of electronics with a very low failure rate, and typically when it does fail it's dead (not temperamental).

To me it appears that a sensor is not working, and only after a number of start attempts the ECU goes into "Limp Home Mode", and limp home mode runs the engine very rich.
Most likely a bad sensor or connection/wiring for the sensor.

Quality and not quantity counts.

Try to swap the IAC and the TPS connectors.

sensors have been replaced I will be testing the wires later tonight when i am back to the car. the tps connector is not long enough to reach the iac ( i have read about that before so was going to try it but no luck ) my iac is closer to the mass air at the end of the intake pipe, most others i have seen are more on the tb which then the connectors could be swapped

This picture was taken from a 1996 DOHC Sportage, I think your Sportage should look like this one



in this picture the IAC valve is disconnected and rotated, the TPS connector is visible at the top of the photo, the IAC connector is on the left of the photo, not visible.

iac is to the right of the tsp ( as you look at it ) on the intake tube.

How much of your Sportage history do you know? Did that issue start all of a sudden?

i know the original owner had engine problems and had the engine replaced at dick hanna kia about 9k ago, my uncle had got it from him drove it for about a year and then it overheated and started running rough. He parked it figuring it was a head gasket. it set for 2 years til i decided i wanted it, the overheating issue ended up being a thermostat and i check the codes and got tps and iac first, fixed those and it idles and runs great but still has those codes coming up along with the coolant temp sensor which i replaced now also. the thing only has 50k on it and 9k on engine and tranny. i am really leaning towards ecu. i wish there was someone local here in washington/oregon to where i could try out their ecu in my car or vise versa, but my ecu code is K01D.

Was it the dual contact temp sensor that you replaced - the one used by the ECU is the dual contact, and the single contact is solely for the gauge.

One thing you guys have "missed" is early KIAs had lots of ground problems causing all kinds of ECM/ECU problems and bad sensor problems. Check ALL grounds on the engine, frame and especially the ones coming off the ECM under the dash (and a lot of the time under the front carpet) and behind kick panels.
Many posts with many "problems" here cured by correcting corroded grounds and harness connections.
For what it's worth...
