Question about 2003 Ford Crown Victoria

1 Answer

I have a 2003 cvp. As I accelerate to get on the freeway, or under severe load, the check engine light blinks. Code was misfire in cylinder 6. A mechanic felt it was not the coil or the spark plug, but the injector. He told me to put cfoam (sp?) in a full gas tank and see if it helps. My gas pump then went out and I replaced it. This AM, I was driving and accelerated hard and the check engine light started to blink. I pulled over, turned the car off and re-started it, but now the check engine light is on and will not go off. I have not had the time to check the code yet.

More than likely you have a misfire due to a coil. In 11 years of working at a ford dealer as a driveabilty specialist I have never seen a crown vic injector fail. If it has a misfire code again I would replace the coil and plug on the appropriate cylinder.

2002 chevy avalanche hesitates when accelrating and check engine light starts blinking


THE BLINKING MEANS THERE IS A MULTIPLE CYLINDER MISFIRE CAUSING CONVERTER DAMAGE. NOT SURE KNOWING WHAT MOTOR YOU HAVE IF ITS THE 4.2 THERE IS A CAM SENSOR ON THE PASS SIDE FRONT OF THE HEAD THAT GM HAD SEVERAL PROBLEMS WITH. FIND A PLACE THAT WILL PULL THE DTC CODE FOR YOU. VERIFY ITS A MISFIRE AND/OR CAM SENSOR CODE, IF IT IS REPLACE THE CAM SENSOR. YOU HAVE TO REPOSITION THE POWER STEERING PUMP TO REMOVE AND INSTALL THE SENSOR

02 chevy 2500hd 6.0 ses light flashing at40mph an gose out at 75mph


The SES light flashing means the engine management software has detected a misfire condition resulting in exceeding 3 times the federal limit of emissions. Under heavy load such as acceleration one or more cylinders are misfiring and once cruising speed is reached the engine is under a lighter load (10 to 20 percent ) that is why it stops flashing several causes of misfires are worn spark plugs ,spark plug wires, faulty ignition coil or coils fuel injector or fuel pressure problems a quick check of the computer to retrieve trouble codes should identify the problem cylinder or cylinders and will direct you in the right direction to find the faulty component but will not tell you exactly what is wrong certain test must be performed to isolate the cause.

Vehicle vibrates under acceleration but when you back off vibration disappears - saab 2.2 tdi


If this happens when acceleration in a straight line, it indicates either a cylinder misfire, in which case the MIL lamp will be lit or, you have worn CV joints at each end of the drive shafts to the driven wheels.

Outer CV wear is usually manifest by a 'rhythmic clicking' on turns under load. Vibration usually is inner CV wear.

Check engine light flashing and car idling low. 2003 Passat V6 4Motion. Recently replaced the timing belt. Was told this is unrelated. Need to replace Cam Belt for cylinders 4,5, and 6


First things first. The check engine light is blinking because the engine is misfiring to a point that could damage the catalytic converter. If cylinder 4 5 & 6 are all misfiring i would check the engine timing belt for proper installation. These are the cylinders for the left bank of the engine. If the belt has jumped or was installed wrong this would explain the misfires. Unfortunately this is an interference motor which means there is a high probability if the belt is on wrong, the engine valves mat be damaged. I would perform a compression test on those cylinders to verify the belt condition. Hope this helps.

Engine check light& error code p0301 on my 2003 rav 4,


Unless your computer in your car is faulty... the check engine light came on because it, or one of your vehicle's many sensors detected something within your vehicle was not operating under preset factory conditions. Fortunately, the error code that was extracted was indeed a cylinder # 1 misfire, which is fairly basic. Could be a bad spark plug, wire, etc. or you may have gotten some condensation inside the plug boot. Your mechanic did indeed clear the code, but drive it for awhile and see if it repeats. Normally with a cylinder misfire, you'll notice a small stutter when you accelerate or idle. If your Check Engine light returns, have the codes extracted once more. If the same cylinder is misfiring, have him replace the spark plug and wires.

2003 cavalier trac and engine light on


you are probably throwing code p0300 random misfire. it sounds like your ignition module which sits on the top of you engine it is silver with find and held in with 3 torx screws it controls 2 cylinders at a time so when it goes your car will be only running on 2 cylinders this can severely damage you catalytic converter. and a dealer won't cover it under the emissions warranty. the module costs around $100 so you might want to diagnose it.
