Question about 1996 Chevrolet Suburban

1 Answer

1996 suburban random misfire or runs rough changed the following sensors: O2 (all four) MAF IAT ECT and PCV, air filter, water pump (flowkooler), thermostat, cleaned ground connections then I added Lucas fuel system cleaner and now seems like the engine is not getting fuel and cuts out changed the fuel filter no improvement suspect fuel pump, due to fuel cleaner additive would like advise before changing the fuel pump ($410 at local shop)

    same problem. Have changed the distributor, cam shaft position sensor, O2 sensor, sensor wires, spark plugs. No luck. Any suggestions? will check compression and injectors next, but not indicated by fault readings

I would check the fuel pressure first if it is in the good ranges then your pump is good. have you checked your spark plugs and wires? if not i would, if bad replace. otherwise i would have the ignition coils checked to find out if they are working correctly. that is all i can think of. good luck

Rough idle and smells like gas when driven


When checking for Vacuum leaks, did you use a water spray bottle on seams and vacuum lines and EGR pod?(engine running)

Check for air leaks in exhaust before O2 sensors. O2 thinks its running lean from air leak in exhaust header and enrichens fuel charge.

Fuel injectors dirty, not closing tight. Switch injectors to other bank and see if Error Code moves to relocated injectors.

Bad spark plugs, check if you have fuel runners in your intake.

Check engine light is on. Does replacing the oil filter fix the problem? The codes are: P171, P174


very Unlikely this will have any affect. sounds more like an air leak to me.
You will find all codes available at http://www.bluejag.co.uk/decode.php



Fault Code:- P0171 Indicates a Power-train fault


The fault is generally due to a problem in the Emission Management (Fuel or Air) area


Fault Description: Bank 1 combustion too lean

Action of ECM:- ECM Default:- Bank 1 catalyst warm-up ignition ****** inhibited- Bank 1 closed loop fuel metering inhibited- Canister purge inhibited- Maximum engine speed reduced


After clearing the DTC, complete the Start engine and bring to normal operating temperature> 82 °C (180 °F) Idle for 10 minutes
Check for a reoccurrence of fault DTC.


Possible Fault:- Engine misfire Air intake leak between MAF Sensor and throttle Fuel filter / system restriction Fuel injector restriction Low fuel pump output HO2 Sensor(s) (1/1, 1/2) harness wiring condition fault Exhaust leak (before catalyst) ECM receiving incorrect signal from one or more of the following components: ECT Sensor, MAF Sensor, IAT Sensor, TP Sensor
Fault Code:- P0174 Indicates a Power-train fault


The fault is generally due to a problem in the Emission Management (Fuel or Air) area


Fault Description: Bank 2 combustion too lean

Action of ECM:- ECM Default:- Bank 2 catalyst warm-up ignition ****** inhibited- Bank 2 closed loop fuel metering inhibited- Canister purge inhibited- Maximum engine speed reduced


After clearing the DTC, complete the Start engine and bring to normal operating temperature> 82 °C (180 °F) Idle for 10 minutes
Check for a reoccurrence of fault DTC.


Possible Fault:- Engine misfire Air intake leak between MAF Sensor and throttle Fuel filter / system restriction Fuel injector restriction Low fuel pump output HO2 Sensor(s) (2/1, 2/2) harness wiring condition fault Exhaust leak (before catalyst) ECM receiving incorrect signal from one or more of the following components: ECT Sensor, MAF Sensor, IAT Sensor, TP Sensor

I would like to know what the following codes represent for my 2002 jaguar x-type 3.0 Codes are P174, P175, P1111


P1110 Intake Air Temperature Sensor Signal (Dynamic Chamber) Circuit
The other DTC refer to mixture issues.

From http://www.bluejag.co.uk

Fault Code:- P0174 Indicates a Power-train fault
The fault is generally due to a problem in the Emission Management (Fuel or Air) area
Fault Description: Bank 2 combustion too lean
Action of ECM:- ECM Default: - Bank 2 catalyst warm-up ignition ****** inhibited - Bank 2 closed loop fuel metering inhibited - Canister purge inhibited - Maximum engine speed reduced
Possible Fault:-
Engine misfire Air intake leak between MAF Sensor and throttle Fuel filter / system restriction Fuel injector restriction Low fuel pump output HO2 Sensor(s) (2/1, 2/2) harness wiring condition fault Exhaust leak (before catalyst) ECM receiving incorrect signal from one or more of the following components: ECT Sensor, MAF Sensor, IAT Sensor, TP Sensor

once again from http://www.bluejag.co.uk

Fault Code:- P0175 Indicates a Power-train fault
The fault is generally due to a problem in the Emission Management (Fuel or Air) area
Fault Description: Bank 2 combustion too rich

Action of ECM:- ECM Default: - Bank 2 catalyst warm-up ignition ****** inhibited - Bank 2 closed loop fuel metering inhibited - Canister purge inhibited - Maximum engine speed reduced


After clearing the DTC, complete the Start engine and bring to normal operating temperature > 82 °C (180 °F) Idle for 10 minutes

Check for a reoccurrence of fault DTC.

Possible Fault:- Restricted air filter Leaking fuel injector(s) ECM receiving incorrect signal from one or more of the following components: ECT Sensor, MAF Sensor, IAT Sensor, TP Sensor

1996 es300 trouble code po172 and misfireing on all cylinders


Whats going on here is that you have a too rich fuel air mixture. This will cause your misfiring and set off the PO172 Code. Your Bank 1 O2 Sensor is picking up the too rich mixture. This O2 sensor is location on the #1 Cylinder side (so you problem could be in #1/#3/#5 Cylinder). A dirty MAF Sensor, loose plug wire, dirty/broken spark plug, dirty fuel injectors, vacuum leak, and PCV Valve could all be a cause. I would run some injector cleaner through and also clean the MAF Sensor, change your PCV Valve. This would be an easy and cheap start for you. Good luck and thanks for using FixYa!

Sincerely,
JC

Replace the coil packs.
Your issue is NOT the converter, or you would have a P0420/P0430 code
