One or more fuel injectors may become stuck closed causing an engine misfire  and the Check Engine Light to illuminate. Our technicians tell us that this problem can be caused by some fuel additives. There are special procedures which may be able to restore the affected injector. If this fails the affected injector must be replaced.

    I think i have the same problem with fuel injector. The check engine light starts blinking when i go up the hill. I already replaced the catalytic converter. But that didn't help. I consulted with technician and he that that the problem is in the fuel injectors

    Misfire on cylinder 4. Started happening when I switched from premium gas to regular gas. I used premium gas for the longest time (as this van "appeared" to do better with gas mileage with premium 10.5mpg to 11.5mpg all local stop-and-go driving), but when gas got up there in cost switched to regular gas. It took about 6-9 months but then the check engine light would flash. I through a bottle of techron in it and it went away for a while. It came back so since then I've switched back to premium gas and the misfire hasn't reappeared...

    Check engine has been on for a few months and the engine misfires, backfires, and chugs when you first start out. After it warms up it is fine. Today it stopped working. When you turn the key, you don't even get a click. Have cleaned battery terminals and posts, but i still does not even click. Ideas?
