SOURCE: service engine light is on in my 2004 Buick LaSabre

the service engine soon light means a fault has occurred in the engine or emission system's electronic controls, it has nothing to do with any service you did in most cases, there are over 150 problems that turn the light on, to find out what the problem may be go to any Kragen Auto or Autozone parts store and ask them to run a OBD 2 trouble code test, IT IS FREE. then post the code back here for us to look at, which is also FREE.

SOURCE: 1990 buick lesabre when in drive seems like its in neautral

Hello, I'm not sure if you are still dealing with this problem, but here are a few tips.
1.When the car is running and at normal operating temperature, check the transmission fluid level. If the transmission fluid level is low, this will cause the Transmission to slip when in drive.
2.If you transmission fluid level is low, this usually indicates you have a leak. Transmission fluid does not need to be changed like other fluids such as oil.
3.You may also want to add a "stop slip" agent to you car, this may help or possibly correct the problem.
4.If all else fails, I would recommend you take you car into a certified Transmission shop. Please vote or rate this reply if you found this reply helpful.

Rav 4 misses under acceleration


well if engine is ok. No year, no engine stated, wow. !!!
misfire is bad combustion. (gas usa cars are my answers)
  1. never did a TUNEUP this decade? 60,000 miles tunes.?
  2. bad spark first.
  3. bad fueling next too rich causes misfire. lean bogs.
  4. misfire shakes engine hard, is it .
  5. does it misfire parked just racing engine?
  6. cause are many over 50, but if engine good way less, so what can it be (we do tests no Gue$$) bad spark plugs, leaking injectors execessive fuel pressure, bad TPS, sensor. map sensor issues, (even clogged) and others. no engine stated makes waxing smart, hard, way to hard so i quit here.

2008silverado 4.3v6 has miss when you ecellrate changed plugs doing it again engine light back on


Since the engine light is back on the code is likely to help you diagnose the problem.
1. If you have a code reader for your car plug it in and it should tell you what the computer thinks the problem is.
Remember for the engine to miss it has to be loosing fuel or spark. The spark plugs are only one of the parts required to make a reliable spark in the plug as the engine is running.
2. Check the spark plug wires and the distributor internal for rust contamination around the reluctor magnet area. The 4.3 chevys are bad for this. Have someone start the car for you at night while you look under the hood for spark leakage. In the dark any wire leaking spark enough to make it miss on acceleration will flash blue lights in the dark.
3. Replace the fuel filter.
4. Check for vacuum leaks in the rubber tubing plugged in to the intake manifold.
5. Make sure the battery to engine ground cable is in good condition at both ends and tight.
6. Make sure the battery to chassis ground wire is connected clean and tight.
Good luck.

Intermittent miss at idle and steady speeds


You need to hook up a computer scanner to the engine to find out what the fault code is [indication of what is causing the miss]. The CHECK ENGINE lamp lights up when a fault code is detected and set in the computer's memory. ALWAYS replace all the spark plugs on a Ford when there is a miss. Those "alleged" 100,000 mile spark plugs are really only good for about 60,000 to 65,000 miles. Using them longer than 60,000 miles causes the ignition coils to overheat [from trying to fire the huge gaps on those worn out spark plugs] & fail. Hopefully, you will get a fault code to tell you which cylinder is the problem. When you disconnect the battery, you give the PCM [engine computer] a case of amnesia, and it forgets the fault codes it has stored in it's memory. That's a foolish move, as it only removes the info a "real" mechanic needs to solve the problem. Use only Motorcraft, NGK or Denso spark plugs. Other brands won't last in a Ford product.

Slight miss accelerating


place a inductive timing light on your spark plug wires one at a time;\while the car is in neutral and, running accelerate the engine
when a miss-fire occurs on the bad spark plug wire you will see a missed flash from the timing light's bulb

I have a 1995 Chevy S10 4.3L Engine. What would cause the engine to miss during acceleration??


Have you changed the spark plugs this year ?
Is the check engine light on ?
How's the cap rotor and wires ?
A miss under load is normal when one of the spark plugs is weak or they are not getting enough voltage from the coil. Also, a weak injector or problem with the fuel system can cause a miss.

How do you remove the ignition coil


Each ignition control module (ICM) has the following circuits:
An ignition 1 voltage circuit A chassis ground An ignition control circuit for each cylinder A low reference circuit
The PCM controls spark by pulsing the ignition control circuits to the ICM to trigger the coils and fire the spark plugs. The PCM and ICM are internally protected against shorts to power and ground on the ignition control circuits.

The spark plugs are connected to each coil by a short boot. The boot contains a spring that conducts the spark energy from the coil to the spark plug. The spark plugs are tipped with platinum for long wear and higher efficiency.


Ignition Control Module (ICM) Connectors

To install:

CAUTION DO NOT wipe grease from the module or coil if the same module is to be replaced. If a new module is to be installed, a package of silicone grease will be included with the module. Spread the grease on the metal face of the module and on the cover where the module seats. This grease is necessary for module cooling.

Replaced coil, spark plugs,plug wires, rotor and rotor cap, and the part under the rotor (forget the name) car has a miss when idleing and when getting on it, NAPA said the spark plug gap should be .035,...


if this is a four cylinder engine,the plug gap is what NAPA told you,verify you have the right plugs and gap,next remove the cap again and verify the plug wires are pulled into cap where they will lock in.

Replace plugs and wires at the same time and this will fix it. It is not a transmission problem. Common customer problem at a dealership I worked at. Carbon tracking on plugs and wires will cause this , so replace both at the same time to fix.
