2000 Kia Sportage Trouble! Please help!?

[jcmartinez_v]

My kia was having trouble starting for the past few weeks. I had to press on the gas while turning the key to get it to come on. I put STP in it and it fixed the starting problem, but now it shuts off when I put it in drive. Any idea what could be wrong?

You still have that 10 year warranty? It sounds like you need to use it for probably a vacuum leak. Have it checked with an OBD II code reader. The car will tell you what its problem is.
