2001 Saturn SL No. 1 Cylinder Mis-fire

I recently took my 2001 Saturn SL to have it's required yearly emissions check performed prior to renewing my registration and for the first time since purchase it failed. I was told by the emission station that the No. 1 cylinder was showing a misfire. The car starts and runs fine with just a hint of vibration. However, when idling there is a sputtering sound from the exhaust. The same sound goes away when the car is above idle. The idle RPM is a constant 750 and never wavers. I have changed the plugs and wires with no change in the sputtering. I changed the wires less than a year ago and originally had two wires crossed, this was quickly corrected. Could this be the reason for the fault code and if so what can I do to have it reset, Any ideas? Also I still get great gas mileage.

    Have the same thing on a 2000 Saturn SL1. Originally had a random misfire. Once sparks and wires were changed the code changed to misfire on Cylinder 1. Plug on Cylinder one was worn out. Others were not too bad. Mechanic suggests changing Ignition Coils next. Not sure if this will work.

Solved my problem: After more internet searching and consulting with my mechanic we determined it was the intake manifold gasket folding over into the #1 cylinder. This is common on Saturn engines. The gasket folds over leaving a leak in the vacuum system which causes the car to run lean. Check for a leak by spraying carburator cleaner around the #1 cylinder intake and you will hear the idle change if there is a leak. I had gasket replaced for $450 and car runs like new. My car is a 2000 saturn SL 1 with 60000 miles on it. Hope this helps someone.

The intake gasket is know to "fold" on #1. Spray the #1 intake runner, where it meets the head, with some brake clean. With the engine running. If the idle changes, it is leaking. Replace the gasket.

Firing order for a 4 cylinder Saturn 1998 Class AD model 4 door. I am not sure if it's an SL SL1, or SL2.


all Saturns for that year came out with a 1.9 liter engine. There was only one model that was different and had a single overhead cam. The rest had a duel overhead cam. The firing order is the same in both so you are in luck (see picture below). I hope this helps and good luck.

I have a '03 Toyota Celica GT-S with a annoying mis-fire. Started small by replacing all spark plugs - nothing. Replaced the MAF sensor - nothing. Took it to a authorized toyota shop & checked...


Replaced the MAF sensor - nothing. Took it to a authorized toyota shop & checked compression which check out good and put the computer on. Computer read mis-fire on cylinder 1, and then multiple misfire (like it would jump around). We went ahead and replaced the fuel injector on cylnder 1 - did not solve problem as when we hook the computer up, misfire seemed tp stay at idle and seem better when running high RMP, but check engine light is on as it never went away. Went ahead and replaced the coil pack to cylinder 1 - nothing. what am i missing?

Honda Prelude 2001, 2 codes seem to pop up all the time, P0420 and P0301. What has the to do with the other? Can the Catalytic converter cause a miss fire?


Hello: Sir, the 301 is telling you that you have a mis-fire on cylinder #3, You may have a bad spark plug, or bad wire going to #3 plug or you may have a ignition unit that is not firing #3 cylinder, With the #3 cylinder not firing it caused the 420 code that means the catalytic converter to be below acceptable efficiency for emission standards. Repair the 301 before you replace the converter

How can I clear the misfire on #4 cylinder code?


If you have not repaired the #4 mis-fire problem then re-setting or clearing the code will only last until the mis-fire is detected again (maybe only minutes or even seconds depending how bad the mis-fire is), and then the MIL (malfunction indicator light) will be right back on. Try changing the #4 spark plug and ignition wire first, if this does not solve the problem then there might be something more seriously wrong with your engine.

If you do not have a scanner to reset the MIL, then you can reset the MIL by dis-connecting the battery for three minutes and then re-connect the battery, and all of the data trouble codes should be cleared.

Error code p0301 and p0306


The code 0300 is a mis-fire code. It means at one point a cylinder has mis-fired. When you are given the the code 0301 it points to the # 1 cylinder, 0306 is # 6 cylinder. Here is a long list of what these codes could mean as far as diagnosing the problem :

-Fuel injectors, related wiring, sensors and computer issues
-Running out of gas, or poor fuel quality
-Evaporative emissions system (EVAP) concerns: fuel vapors leaking into engine
-Incorrect Fuel Pressure
-EGR system concerns
-Base engine concerns: low compression, valve train problems and timing issues
-Ignition system concerns including, but not limited to:
Faulty spark plugs
Faulty coil or related wiring
Ignition module or related wiring issues
Ignition related sensor faults or wiring issues
You will have to determine which or may be several, of these items to check out.
Please let me know what you find.
