Went to Autozone got the codes.
Threw 4.
1. PO201 Fuel Injector circuit condition - injector #1
Probable cause:
a. Open or shorted fuel injector(s)
b. Open or short in electrical circuit
c.High fuel pressure - pressure regulator - defective - fuel return line blocked
d. Check TPS and circuit for failure
2. P0122 (Throttle Position) sensor
Probable cause:
a. Sensor open or shorted internally - replace component
b. Check connector and wiring to sensor
3. P1391 CMP or CKP signal intermittent condition
Probable cause:
a. Timing belt or chain stretched or jumped
b. Defective CMP sensor
4. P0171 Fuel trim bank one condition - computer has recognized a rich or lean condition on one engine bank only.
Probable cause:
a. If bank One and Two codes set together suspect fuel pressure or MAF sensor
b. Oxygen sensor defective
c. Ignition misfire - repair
d. Fuel injector problem
Now where to begin???
Suppose I'll pull the plugs today and check their condition/Gap first.
Did not misfire this morning but I only drove about 10min there and back from Autozone.
All guages dropped out on way home. Check engine light went out - AIRBAG light came back on.
Got the codes-bought some oil/filter and new Champion copper plugs just in case I find bosch or something else in her. Gonna inspect cap rotor and wires first.
I'll keep y'all posted.
