So I was in the parking lot at work today and I stepped on it a bit to show my buddy the loudmouth exhaust. It didn't really pickup, instead sputtered then caught back on and accellerated slowly. I was confused but it drove fine after that, so I let it go. Then coming home from work I got on it a little bit on the main road. It started sputtering again in low RPM's, then eventually stalled after trying to accelerate at a light. After cranking it for about 5 seconds it started back up and I took it to a nearby gas station. I let it idle with the hood open and it seemed to be idling fine. The fans didn't turn on til about 240-250 though, when they usually turn on at 220-225.

I let her cool down, drove her home...now I'm a mess because my baby's sick lol. There's no engine light, which i'm not happy about. I'm thinking either something ignition-related or fuel pump. What do you guys think? Thanks

 

Check fuel pressure and your opti and the coil.

 

another thing that happened that I forgot to mention:

Yesterday I raced a stang on the freeway and I was reaching speeds around 120 mph. After roasting him I stopped to get gas, and after filling up my tank I put the key in the ignition and as soon as the fuel pump started to prime, the power to the car went completely out. It was as if I disconnected my battery. So after freakin out, I took off the negative battery terminal, then re-connected it. Started right back up. Not sure if this helps diagnose anything or not? Thanks a lot guys.
