Question about 2003 Buick Rendezvous

1 Answer

Check engine light report: cylinder 2 mis-fire, engine skipping, hesitant acceleration,

The hesitation,skipping and rough running started suddenly and i took the car to auto parts place to have them check with their "reader". It came back as a cylinder 2 misfire. I replaced the spark plug (although it was firing just fine) still having the same issue. Also all of our vehicles are the doing the same thing.(05 chevy colorado, 03 cadillac and 03 rendezvous) went to local dealership, they said that GM is blaming this issue on ethenol in fuel. I have added "good" fuel system cleaner to gas tank on all 3... not sure what else to do

Use a different fuel station. First run the fuel tank low before refilling elsewhere.

SOURCE: 99 buick Lesabre

hey thanks for bringing me up to speed. ive been working on many other problems but with your great explanation i remember.
we need to check the compression on that cyl. and compare it to the compression on 2 other cylinders your choice.
but before you do this get a can of carb cleaner . and with the car idling spray around the intake manifold in the area of #6 cyl. what we are looking for is a small vacuum leak that would also act like this. with the engine idling and spraying around the intake the engines idle sould not change and if it does when you spray you have an intake leaking.
let me know how it turns out.
later
paul

SOURCE: "unidentified" Fuel System issue - check engine light on

What you have is a vacuum leak in the evaporative emission line.
The solenoid valve or line is broken allowing un-metered air to enter the intake system and is causing the high idle.
Once the leak is fixed, the codes can be cleared and you should be OK barring any additional problems, but the vacuum leak needs to be fixed first.
Let me know.
Regards,

SOURCE: I have a 2000 buick lasabre that has been running

plugs and or wires.
for some reason the spark is jumping out of the wire or plug.
the plug insulater may have a crack in it.
also use a carb spray to clean out the throttle body at the throttle plate.
all the black carbon will build up around the throttle plate and restrick airflow at an idle position.

hope this helps
thank you
jm

Cylinder 2 mis-fire code on 03 buick rendzvous


The code is telling you the cylinder is not producing power.
The problem could be a faulty spark plug or ignition problem, fuel injector, or mechanical problem such as a sticking valve.

Blinking engine light, rough running, smells like gas from exhaust. Happened all of the sudden.No water in oil. Have to push accelerator to start engine now.Just sounds like it is misfiring.


the blinking light is blinking a code that ID's the cylinder or cylinders that is mis firing, count the blinks, poss causes are defective ignition coil (one for each cylinder) or a defective spark plug, these are the common reasons other problems of course like a dead cylinder from low compression like a bent or burnt valve can also cause this, but that is very unlikely, U don't say engine type so assume this is a gas engine

You have a mis-fire in the ignition system, have Kragen Auto or any chain parts store run a quick test (it's free) to get the code, it will tell you which cylinder is mis-firing.
