Hey everyone!

Help please!!!

Starting to get stumped...Got a copy of the Rave and looking over what little info it has on wiring, all grounds and connections seem to be intact. I recently had the manifold off for VCGs and a full tune up, truck ran amazing for about a day and then stumbled very hard and has been weird ever since. runs fine, but rich and drivability is slightly decreased. Connections and area around ECU seem to be clean and intact.

14 Codes are:

1884 - AIT invalid {Suspect MAF}
0445 - EVAP purge circuit fault
{purge solenoid used to be loud as normal but i no longer hear it activating}
0448 - EVAP system vent control circuit
0102 - MAF low input {Suspect MAF}
1590 - ABS rough road circuit malfunction
{I read that this can be caused by a misfire detection miscommunication as well}
0340 - CPS circuit malfunction

0135 - O2 heater malfunction Bank 1 Sensor 1
0155 - B2S1
0141 - B1S2
0161 - B2S2
0134 - O2 sensor no activity B1S1
0154 - B2S1
0140 - B1S2
0160 - B2S2
{All 4 sensors are dead in the water out of nowhere????}

Thank you!!!

 

UPDATE: did unplug while running on the MAF, no change. While MAF may be bad, I'm still suspecting ground issues

 

Fuse #2 was blown, will report back what all that fixes.
