ok i'm thinking something is getting hot maybe, in the morning or when i first leave from home the car runs fine, but by the middle of the day or end, it runs like a pos, studdering, bad idle. etc etc.

 

I had the same problem, But my car didnt sstudder....it sounds like your fuel pump because in the morning your car puts more gas in to warm itself up (richer) and during the day when your car is warm it cuts back on the fuel...OR....your fuel pump is bad and heats up during use, which means the pump gets weaker forcing less fuel into your motor

 

like he said but I would check the pump, the relay the filter the injectors and the fuel line to make sure it doens't have any leaks and isn't too close to anything hot.

do it from easiest to hardest of course

 

sucked up, brought it to my mechanic,,,, it was the rotor had eaten through the dizzy cap? go figure, but someone just put that one there this past christmas, aparently it wasn't right, or not tight, 85 bux later, new one on, car runs perfect.
