Hello, I have a 98 Amigo 4x4 4cyl. 5 speed. I''m having problems with my engine and have a check engine light on. I went to advance and they checked it and stated that the number 4 cylinder misfire. I had just put new plugs and wires on a year ago. Also I just put in a bottle of injector cleaner in. I''ts funny that when I first crank the engine it idles fine but when you start going forward it acts as if its not getting fuel, but as I run it longer and the engine warms up it operates better. I checked the plugs ang they don''t look fouled. Advane says to replace the wires but I already did that a year ago. Also Advance stated that if the coil was bad it wouldn''t run at all. Has any one had this problem. Thanks for any ideas.
