jowens Posted November 2, 2005 Share Posted November 2, 2005 Have a '90 Legacy wagon 2.2 automatic. Don't know what to do next. Engine is misfiring and so far we can't get it resolved. Our mechanic is still trying to figure it out. We have replaced air filter, spark plugs, spark plug wires and replaced 2 fuel injectors. It is still misfiring. What do we check for next? Any help would be greatly appreciated. We need this car fixed badly. Link to comment Share on other sites More sharing options...
Cougar Posted November 2, 2005 Share Posted November 2, 2005 Some folks have cured the problem using Seafoam to remove carbon deposits in the cylinders. They rev then engine and suck up about half the container through a vacuum hose tied to the intake and the other half is poured into the tank.

Legacy777 Posted November 2, 2005 Share Posted November 2, 2005 Have you or your mechanic tried to check and see if any codes are stored in the ECU? Instructions are on my site. I would start there. Link to comment Share on other sites More sharing options...
tunered Posted November 2, 2005 Share Posted November 2, 2005 the 2 injecters you replaced are they across from each other? the coil pack as i understand it works in 2 halves,1-2 fires on the front half 3-4 fires from the back half. ed Link to comment Share on other sites More sharing options...

Right now only #2 is misfiring. Thanks! Link to comment Share on other sites More sharing options...
beezer Posted November 5, 2005 Share Posted November 5, 2005 Is the "check engine light" on? If it is I would deal with this first. Is there a spark going to each cylinder? If there isn't I would check the coil pack. It seems weird that one side would fire and not the other, but, its worth looking at. Check the igniter as well. If both these check out fine I would take another look at the plugs and wires. Possibly change fuel filter if you haven't already. Are the injectors working, you should be able to hear them click if you hold a long screwdriver to them. Run some seafoam through the intake to clean it out. Good luck Link to comment Share on other sites More sharing options...
