Check engine light

Code say's misfire..complete tune up..still on..new exhaust..haven't done the o2 but i didn't think that would show a misfire..runs excellent...light has been on for months..just getting real annoying and it won't pass inspection.

98 dodge ram 1500 5.9L 2wd. Truck runs really rough, stalls, then won't start. No check engine light now. Had misfire codes, did tune up, now it still stalls and no check engine light.


What is the O2 sensor reading? If it runs rough check the engine compression, run an injector flow test and clean and replace as necessary. Check the EGR for leakage. Drive it and see if the misfire codes return, I think they will.

ENGINE LIGHT ON CODES P0141 & P0144


code p 0141 refers to heated oxygen sensor (HO2S) 2 bank 1--heater control--circuit malfunction===causes --wiring---HO2S--- ECM
code p 0144 refers to heated oxygen sensor(HO2S) 3 bank 1--high voltage ===causes wiring short to positive ---HO2S---ECM
also refers to oxygen sensor(O2S) 3 bank 1--high voltage ===causes wiring short to positive---O2S-- ECM
HO2S sensors are the units in the exhaust manifolds or before the cat converters
O2 sensors are after the cat converter
two completely different operations
use the special tool for sensors as the wires are easily damaged from the wrong tool use
as for misfiring you will get a P0300 (0300,0301,0302,0303 etc) depending on which cylinders are misfiring
when checking for misfiring the injectors , (blocked or not firing) are as important as plugs and wires
If the misfiring continues after sensor replacement , replace the ECM with a known good one as it is common to all fault codes and misfiring

Sounds like you have a serious vacum leak.; DTC 0174 and 0174 are lean conditions on bank 1 and bank 2, 0300 is random misfire. The only thing I can think of is a big vacum leak like the brake booster / vac line leaking, or maybe the intake manifold is cracked ... even a stuck-open EGR doesn't normally lean a motor that much. Start by checking for a vacum leak, if the motor will idle you can spray a little WD-40 around ports and lines >> if the idle speeds up or becomes smooth you on the right track in the area you judt sprayed.

2002 330 i misfire with low fuel


it could be your exhaust sensor. If it is not sending the right information to the computer than the computer will adjust the tuning to suit.I hope this helpsregards

Rough running under load both o2 sensors changed with new plugs. I think the trouble light was on too long and sum how killed the converter


did you check the coils and plug boots when you replaced the plugs? often times the coils get weak and don't complete the burn to the plugs. also check the connections at the coils to make sure no terminals got bent when you plugged them back up. the convertor can be bad or will go bad if the engine running problem isn't corrected.does the check engine fault codes reveal misfire codes or catalyst below efficiency code? the misfire codes need to be fixed first.

My check engine light is on and I just had a diagnostic run, and the following codes came up: P0300 Random Multiple Cylinder Misfire, P0305 Cylinder 6 Misfire, and P0058 Oxygen Sensor. The mechanic...


Hi, check the wiring on the sensors for contact with the hot exhaust. The wire may have melted insulation (you may not need a sensor but just a wiring repair). The sensor is screwed into the exhaust pipe behind the catalytic converter. There is one on each pipe. Code 58 is bank 2, which I think is on the passenger side. The O2 sensor may possibly cause the other codes too, but I have a post on misfires you can browse.

Please see my tip at http://www.fixya.com/cars/r6715318-causes_gasoline_engine_misfires . These are generic instructions. If you get stuck or need specific instructions for your car, please get back to me with model, year and engine info.

If the code 300 is not being caused by the sensor, then a tuneup may not resolve the issue. For example, a code 300 can be caused by the crank sensor, and that is not part of a tuneup. So $350 later you may still need more work.

1996 Voyager van has check engine light on, will stall out at lights and even when moving, like on the highway. Someone said it could be the oxygen sensors, could this be the problem? FYI, the van has had...


First thing, and it costs nothing, is clean the throttle body interior thoroughly. Lift the throttle plate with your fingers and make that interior spotless, pay special attention to the rim of the throttle plate too. OK check out how it runs. If the problem is still there have a garage or Autozone do a code read from on the on-board diagnostics (OBD). If the car is exhibiting rough engine running I would check spark plug condition and the efficiency of the spark plug holders/leads. If when the car stalls does it start up directly or is it reluctant. If the former, change the cam sensor and if the latter, change the crank sensor. Both sensors when faulty also give rise to intermittent misfire events. At the age of your vehicle I would replace both as an insurance policy as they both have finite life. If no codes show on OBD replace the O2 sensor on the exhaust manifold. O2 sensors deteriorate with age and often give problems before the on OBD can detect them. The fact that you have a CEL also indicates an emission fault which points to an O2 sensor signal outside of normal range.

You may need to look at your exhaust system. If you have a leak, your O2 sensors will send the wrong reading to your engine which will in turn tell your engine to fire differently. Your code will come up reading as a misfired bank. See if you have an exhaust leak first, then see about changing out the O2 sensors behind the leak.

Runs fine until it hits temperature then misfires?


o2 sensors are swapped by mistake! make sure the correct wires are plugged into the corresponding sensors. did you have exhaust or other o2 sensor work done? possibly a failing catalytic converter but unlikely. Check engine light?

The only way, for shure is to go to computer diagnostics. 99% sure that this is some engine sensor, buy only diagnostics will tell who. (130,000 miles, hm lamda. it have only 150,000km live)
