    As a follow-up, car has been very sluggish, and especially when cold, very rough ride. Several times car has bucked. Car has 300,000 miles, but has been running well until this happened. Check engine light has been on for some time

P0301 - Cylinder 1 Misfire Detected.

Possible Causes:
- Improper spark plug at cylinder #1
- Insufficient compression at cylinder #1
- Incorrect fuel pressure
- The injector circuit is open or shorted at cylinder #1
- Fuel injector #1 may be faulty
- Intake air leak at cylinder

Possible Solutions:
- Perform Injector Service
- Replaced Spark Plug #1
- Replaced Injector #1
- Replaced Ignition Coil #1

Being you have a heavy gas smell I would look into the injectors. If injector #1 is over producing it can cause a misfire. Test your compression and fuel pressure.

Multiple cylinder misfire


There could be a couple of reasons for this. If you are getting multiple misfires then usually it has something to due with the plugs going bad. It also depends on how many miles you have on the plugs and the wires. The other problem could be with the ignition coils or the ignition module.

Getting firing code error for cylinders 1,3 & 5 on my 1999 Sonata


I was wrong about the distributor being round (I was thinking about my other car). I found variations about the firing order but after troubbleshooting, varified the plug wiring order from the front of the car is 1 - 4 - 5 - 2 - 3 - 6 not 1 - 4 - 5 - 2 - 6 - 3 found on several web sites. From the front of the car looking at the engine, the back three cylinders by the firewall going from left to right are 1, 3, 5. The front three are 2, 4 & 6.

2001 hyundai sonata stalls at highway speeds. Had code read and code said misfire on all 4 cylinders. Why?


dear friend- can you be more specific with the conditions and fault codes.this sounds like your TPS sensor is instructing the ECU to cut the feul,therefore there must be another fault code.
