I can't get my car running correctly. I thought it needed a tuneup, so I got that put on and it's still feels like it don't want to drive. Before anymore money spent, I need to know really what's going on with my poor KIA!!!

I bought my 2002 Kia Rio second hand unfourtunally 1 month and 6 days ago. Since then I have actually been able to drive it 5 whole days but not consecutively. My mom was helping me out and I'm paying her back due to financial situations and she lives 2 and a half hours from me.We put a new battery in it since one in it was coming back bad. I drove it home and only problem I noticed was a shimmy on the interstate between 56-69 Mph. Ok figured it was a tire. Drove it about 150 miles total after I got it home where I live in the country. The second day I had it I was driving without any indication that something was going to go wrong it stop shifting up a mountain and was reving to 4000 rpms. Well I'm in a middle of a snowstorm nowhere to pull off so I keep it going trying not to lose momentum at this point get to the top of the mountain still not shifting. I then have the bright idea to start manually going through the gears(automatic transmission). It works for a short distance still snowing at this point semis everywhere on the interstate that can't stop! So I keep on trucking it to get to the next exit. Then one by one the gears stop shofting (its reving high and jerkin into gear whole time). So automatically I think its the transmission. I have it towed to the shop its reading misfire cylinder 2&3 and misc misfire, solinoid in torque converter and a whole list a total of 24 codes don't have all in front of me or I'd list them. Well the shop has my car for 4 weeks, changes fluid, filter and gaskets in transmission, solonoid for torque converter, checks plugs and wires, changes coil packs, beats out transmission and pan( they said it took a hard hit and was dented in), fixed the exhaust and informs me that the catylic converter will need replaced but they knock a lot of gunk out. Ok fine after $1,085 worth of work it seems to be tip top! Drove it a little less then 48 hours same problem starts again same misfires but no other codes only this time it's shifting but really hard. Look it up on YouTube similar car it was catylic converter. Ok he said it needed changed get it done another $145. Drive it home the check engine lights still on but shop tells me before I leave it won't go off but is running great. I agree yes its running great. Get down the road to get on the interstate... Hold up what's that a hard shift but shifts fine after that. Ok it must be ok maybe my foot wasn't level and made it shift funny. Get off the interstate does it between 1st and second again then between 3rd and overdrive and stops. Take my boyfriend to work and only hard shifts once. Get back on the interstate and won't shift and is reving to 4000 rpms but got up to 65 mph. Then all of a sudden my airbag light comes on while my wipers are on they slow way down like they want to quit, rpm gauge starts jumping so I turned my wipers off rpm gauge still jumping but not as fast turn the head lights off quits goes to 4000 rpms but won't shift. I whip it around in the median and head back to my boyfriends work. Called my mom she said to unplug the negitive terminal and let it set for a couple hours. Ok I'm willing to try anything. 2 hours later plug it up and codes have cleared! Yay! I get it in nail it across the parking lot to see if it will shift. Its shifting hard again but woowee it's shifting! Well I decide to sit at work and wait for my boyfriend cause I don't know if I'll make it back at this point. He had tighten the terminal good I watched but when we went to leave it wouldn't turn over. You could hear it click and a wuh wuh. Ok cheak the terminals they're good. Try again same thing. Get a jump starts right up! Yay! Drive 50ft and it dies like someone turn it off and and the exact moment everything went dim. Now once again of needs towed. What do u think now? I've about given up on this car. I'm desperate and just glad my kids weren't with me!

Like a bat out of hell

I was told it would cost $800-900 to replace.I can't afford that. Can you help me would it be better to buy the part then take it to my mechanic, if so what sites are good to purchase from or what auto store to go to for a good price.

Was told I need a new a/c compressor, it started out that my a/c plowing warm air, making a sound from the a/c. Had my mechanic figured it just needed freon, but then soon after it went warm again, mechanic look into it said I need a a/c compressor.

I'll start and drive my car for a couple miles and then the car will shut off like I have just turned it off. Has anyone else encountered this issue and know how to fix it? I have checked and cleaned the connections for the battery and also the spark plugs, we still have no idea what could be happening. It seems like it could be electrical. Any ideas would be greatly appreciated!

i talked to advance auto they say they are bolted,i called a kia dealer and tthey said they were pressed,whos right?

Ran OK when wife drove to work,next day just cranks over but won't start
