I did a run with my new exhaust and afterwards the car started running funny. I pulled over and it settled down. I then drove home and everything seemed fine. The next morning I get in the car and the CEL was on. I took it to Autozone and had them run the codes. I don't remember the exact code numbers but it was a MAP sensor, lean on cylinder 1, and coolant temperature too low.
Later that day I jacked up the car and inspected the exhaust. One of the clamps (first one after the resonator) had come loose meaning I prolly had a good exhaust leak. Could that be what is causing the CEL?
I have driven about 100 miles since I retightened the clamp and checked all the other clamps. I have an appointment on friday morning to have a shop look at it but in the meantime want y'all's opinions.
Ok, took the car to a shop. They ran the codes and pulled a bunch of them. I did what they suggested (replaced the MAF sensor) but the light stayed on and the car still ran funny (like it had no power). I had the codes cleared and the next day it came back on. I did this hoping that less codes would come back. It worked. lol Only problem is that I still can't figure the bastard out.
The car drives fine till you get to 3,000 rpms then its like it hits a wall. The vacuum side of the vac/boost gauge acts weird too. When I go to leave a light or stop sign it goes from 20 psi straight to 0 psi with me not pressing the pedal hard at all (didn't used to do that). Also, when cruising it used to stay between 20 and 10 psi and when going up hill may get halfway between 10 and 0 if it is a big hill. Now it goes between 10 and 0 psi when cruising and goes to 0 psi when going uphill.
Ok, any suggestions?!?!?! lol

Maf sensor is brand new. Air filter was changed out for the factory filter. (newer then the cone filter that was on it). The guy that pulled the codes showed me the scanner screen and I wrote them down. Even compared it to the list that is in my Haynes manual.
