No problem. Sometimes all of us start off wrong on a site but you did have one of the best helping you. You might want to get that fixed because his knowledge does come in handy. It has for me more times than I can count.
Now, if you have around $100.00 to spend, I would go buy these things.
1. New MLPS
2. CRC MAF cleaner
3. New TPS
4. New air filter, if the one you have is dirty.
5. Throttle body gasket
Installing the MLPS is simple to do. Unplug, unbolt the two bolts, slide off, reinstall the new one and make sure it's lined up as it should be and bolt it down and plug it in.
Remove the 4 bolts from the air box using a long flat head and take the air box out after unplugging it. Take the MAF out so that you can see both sides. Spray both sides of it and get it good and clean. Let it dry for a few minutes before putting it back together. The bottom bolts of the air box are hell but it can be done.
Once that's all done, remove the air intake tube, remove the pass side wiper arm, remove the pass side cowl. Have an 8mm socket with a ratchet ready and some extensions. take out the two bolts holding your throttle cables in place. Now go to the throttle body and remove the 4 8mm bolts holding it on. When you have the throttle body loose, pull up on it and on the back side of that, you'll see a plug holding it down. That's your TPS. Unplug that and pull the throttle body up and lay it over the intake.
Two screws holds the TPS onto the throttle body. Take those out, remove the TPS you have on now and replace with a new one. Get your new throttle body gasket in place. By now, your back should be feeling some pain, from bending and getting the gasket to stay in place is annoying and sometimes a little dab of elmers glue but only enough to kinda help hold it still. Don't forget to plug in the new TPS before you bolt the throttle body down. Once it's tight, put your two throttle cable screws back in place and then put the rest back together. You should be fixed after all of this unless you have bad solenoids inside the pan of the trans.
Maybe just trying a new MLPS first will fix it. Try one at a time but cleaning the MAF is simple and cheap as hell to do and it can't hurt anything.
