I gave my car to a "mechanic" who later called me to inquire as to the correct firing order. I've since gotten my car back, but I'm afraid he might have gotten it wrong. I now know that it's 1-3-4-2, but how do I check if he got ot right. My car doesn't have a distributor, and it sounds like it's misfiring one ore more cylinders.
Go to www. automecanico.com this site is spanish, however all information come in english you can download from pdf is VERY Powerful and complete . see the firing order for you specific model.
God bless you

fuel injectors?, fuel pressure? low compression? even vacum leaks can cause misfires,

If the engine seems like it's OK but you are just seeing a solid Check Engine Light, and if the light has ever mysteriously gone out on its own, check the Knock Sensor. Over time they rust. I have had the repair done on my 2 subies (a 97 and a 99).
The CEL will go out on its own if you have 4 starts with no misfires. If the knock sensor is out, rapid accelleration or steep hill climbing will make the light come back on as the timing advances and the sensor does not ****** the timing for you, so the knocking becomes a misfire.

When cleaning your engine, water/degreaser went down the spark plug ports. Try using a air compressor blow gun to remove the moisture from around the spark plugs and boots. The water was causing the engine to misfire on 3 cylinders at first and as the ports started to evaporate the moisture, the less misfiring was occuring. Dry thouroughly and hopefully coils do not have damage to them. Also check to make sure the boot is making good contact with the spark plug.
