Hello all.
Yesterday while driving on the freeway (65mph) it felt like the car was holding back. more like a pulse or if i were tapping on the brakes. it got worse as i decelerated. i thought it was going to stall on me cause the rev will drop to about 400 the jump to 700. i managed to find a safe place to pull over. checked all connections under the hood and everything checked out ok. i start the car, take off and everything is fine now! WTF? i didnt get any messages on the DIC but here are the codes i pulled up
28-TCS - Traction Control System
C1225 RF Excessive Wheel Speed Variation
C1232 LF Wheel Speed Circuit Open or Shorted
C1291 Open Brake Lamp Sw Contacts During Deccel
C1292 Set Curnt/Prev Ign Cylce
40-BCM -Body Control Module
B2578 RF Turn Signal Monitor Circuit (Short to Voltage)
B2583 LF Turn Signal Monitor Circuit (Short to Voltage)
B0-RFA - Remote Function Actuation
U1096 Loss of Communication with IPC
U1064 Loss of Communication with BCM
U1016 Loss of Communication with PCM
C2105 Right Front TPM Sensor Malfunction
C2110 Right Rear TPM Sensor Malfunction
C2115 Left Rear TPM Sensor Malfunction
what could have caused this? No spark? No fuel?
car has about 105K, any insight will be helpful.
TIA

I'd look at chassis grounds 1st, read the electrical stick at the top of the section.
Also the wiring in the passenger door acordian is a KNOWN issue causing all kinds of issues like this. I think this is also covered in the electrical sticky.

I'm sure you know you can purchase the chaffed wire loom at most auto parts stores. Why not by a new connector pigtail ?
