P0300 is random engine misfiring. Could be several problems. My car had this and I replaced the plugs and plug wires. No change. Checked the three coil units. They seemed ok. I used a new on in each spot and nothing changed. Ended up being the ignition control module that sits under the coils. Relatively easy to change. Costs around $150 at the parts store. This may correct the other codes.

My 2002 buick lesabre custom's service ingine soon light came on, but the car is running normal. what could be wrong with it???


there are lots of things that can be wrong. 9 out 10 times it is just a loose gas cap. If this happened to you then just tighten the cap and the light will go out in a few days. If not then you will have to get your codes read to determine the source of the problem. Many auto parts store will read the codes for free and give you a printout showing the trouble spots.

I have a1997 buick 3.8 car run like **** code reader said missfire on on more then 1 cylinder went to start again and wont crank like it has to much comp batt and starter good


If it is a p0300 code I would look first at the coil(s). My 2002 has 3 coils (2 cylinders per coil). I just went through this problem with my 2002 with the 3.8 engine. I bought one coil and tested it in each spot. No change. Underneath the coils is the ignition control module. That was my problem and I suspect yours. It costs about $140. It is pretty easy to replace if you are a DIY person.

What does trouble code P0171 for a 2002 Buick Park Avenue mean?


Trouble Code: P0171 (3.8L V6 VIN 1 Auto)
Fuel Trim System Lean (Bank 1) Print this code dataprint_icon_codes.gif Number of Trips to Set Code: 2
OBD II Monitor Type: CCM Details
Indicators: MIL Details
Trouble Code Conditions:
DTC P0101-P0103, P0107, P0108, P0121-P0123, P0130-P0138, P0140, P0141, P0201-P0206, P0300, P0401-P0405, P0410, P0440-P0446, P0506, P0507, P1404 or P1441 not set, engine started, vehicle driven at less than 82 mph at 550-4000 rpm, BARO sensor over 70 kPa (10.1 psi), ECT sensor from 68-230ºF, IAT sensor from 64-158ºF, MAF sensor from 2.8-150 gm/s, MAP sensor from 16-105 kPa (2.6-15.2 psi), fuel level over 10%, and the PCM detected the Long Term fuel trim value was more than +20% for 6 seconds. The PCM controls the air/fuel metering system to good overall fuel economy, driveability, and emission control. During open loop, the PCM determines fuel delivery based on sensor signals, without the oxygen sensor input. During closed loop, the PCM adds oxygen sensor inputs to calculate Short and Long term fuel trim fuel delivery adjustments. Short Term fuel trim values change rapidly in response to changes in the oxygen sensor signals. Long Term fuel trim makes coarse adjustments in order to maintain an air/fuel ratio of 14.7:1.

Possible Causes:
  • Air leaks in intake manifold, exhaust pipes or exhaust manifold
  • Fuel control sensor is out of calibration (ECT, IAT or MAF)
  • Low fuel pressure (fuel filter clogged, pressure regulator failure)
  • One or more injectors restricted or pressure regulator has failed
  • HO2S element is contaminated, deteriorated or has failed
  • Vacuum hose is disconnected, broken, leaking or loose
