99 rx 300 I have trouble codes p0300, p0301, p0303, p0305, po172, and p0171.Stomped


codes p 0300 through refer to misfires on each cylinder with the end number ( 301 is no 1 cylinder , 302 is no 2 cylinder ans so on)=== causes --engine mechanical fault , ---wiring---ignition/ fuel ---injector/s---ECT/ MAF sensor/s ---ECM
most misfires are from injector faults like dirty/blocked tips, low fuel pressure , no pulse or problem pulse from ECM rather than plugs and wires and coils
codes p0171 refers to system to lean bank 1===causes ---intake exhaust leak---air system---maf/vaf sensors ---fuel pressure / pump---injectors ---heated oxygen sensor ( HO2S)
code p 0172 is system to rich-====causes ---intake blocked ---EVAP cannister purge valve ---fuel pressure --EGR system---injector/s ---HO2S
couple these two codes with the misfire codes , I suggest you look at the injectors, fuel pressure (too low) from EVAP problem not venting tank, fuel pressure regulator, EGR system

Codes 0171 0174, 0316,0430


code p0171 refers to system too lean bank 1 causes---intake exhaust leak--- AIR system----MAF?VAF sensor fuel pressure/ pump injectors HO2S
code p0174 refers to System to lean bank 2 causes the same except Maf and vaf are not mentioned and hose connections are added
code p0316 refers to misfire detected at star up first 1000 revs causes ---engine mechanicval fault---wiring---ignition/ fuel system--injector
code p0430 refers to cat convertersystem bank 2-- effeciency below threshold causes ----cat converter--- wiring ----HO2S. Personally I would chewck the cat converter first as if it is blocking the exhaust system the ret of the sensors will have irregular readings.

I have a 2001 Kia Sportage Limited with a trouble code p0171 plus I can smell gas if I have a 1/2 tank or fuller. Any idea what it could be?


P0171 HYUNDAI - System Too Lean Bank 1

Possible causes- Intake air leaks
- Faulty front heated oxygen sensor
- Ignition misfiring
- Faulty fuel injectors
- Exhaust gas leaks
- Incorrect fuel pressure
- Lack of fuel
- Faulty Mass Air Flow (MAF) sensor
- Incorrect Positive Crankcase Ventilation (PCV) hose connection

My 99 grand prix bucks and jumps in reverse and when idling in drive or park


The codes pretty much explain the bucking and jumping. The engine is obviously misfiring on several cylinders.

With the P0171 code, the lean condition (and therefore, the misfiring) could very possibly be caused by a bad Mass Airflow (MAF) sensor, a faulty fuel pump, a clogged fuel filter, or a HUGE vacuum leak.

However, the P0171 code can also be caused by excess unburned air/fuel mixture going down the exhaust due to cylinders misfiring for other reasons like a faulty ignition coil, ignition module or bad spark plugs (as well as other possibilities).

So, now you are faced with trying to determine if the lean condition is caused by the misfires or if the misfires are being caused by a lean condition. (PROPER DIAGNOSIS REQUIRED)

Car stopped running while driving diagnostic codes read p0320 and p0171 what is the remedy?


Trouble code P0320 means: Ignition Engine Speed Input Circuit Malfunction

Crankshaft Speed sensor should be replaced.

p0171 is a lean condition for the right passenger side of the vehicle bank 1 on vehicles with rear wheel drive v6 or v8.

Diagonostic trouble codes reported p0171 p0174 p0302 2001 Taurus, only reports P0171


P0171 is system too lean bank 1, P0174 is too lean bank 2, and 302 is misfire bank 1. Look for vacuum leaks. If you don't find them, put a vacuum gage on it can check. The P0171 is almost always a vacuum leak. If not other possibilities are front O2 sensor is too old and should be replaced (if mileage is greater than 100k then replace). Try injector cleaner. Misfires are usually bad spark plugs, but could possibly be caused by insufficient fuel. I've never had a car of mine in bad enough shape to have that error.

P0302 is cyl #2 misfire and the other 2 are lean or rich codes because of the misfire repair code P0302 first and the other 2 codes will most likley clear up.
