96 gs 2.0 auto went to start it and it took awhile and runs really choppy I've got the following dtc
P0120
P0123
P0108
P0113
Feel like its possibly a ground issue any advice is much appreciated thanks.
 
120 is a TPS issue so check that it is plugged in good
123 is a TPS high sensor reading meaning the ECU saw it out of range above its highest value of 5v
108 is a MAF sensor reading to high also and
113 is the IAT Intake Air Temperature sending too high of a signal also.
Check all grounds and connections at those sensors, unhook the battery for 5 mins or so to clear the codes and then attempt to restart it.
 
Thought about the ECU also myself. The sensors are telling it a HIGH value which I hope hasn't burned a trace anywhere.
Glad you brought that up!
 
Or plugged in wrong since it is showing over voltage. Thanks Solomon for the tip!! :thumb:
