OK, about a month ago, I bought this 1989 Dodge Colt. 4 banger, 4 speed, new wires, cap, rotor, tires, radiator, injectors cleaned out, and I think that's it. It had been running perfect, until about a week ago. I thought it was bad gas, but not now, as I just filled it up yesterday. At first, at low RPM's, it was running kinda rough. But when the RPM's got up there, it kicked in. However, it's been getting progressively worse, until today, when I left this evening for something, I have to rev the shit out of it to get it going from a stop. Just to get up to speed (I barley accelerate), I have to almost put it to the floor and rev it out through every gear. Every gear, every RPM it runs very rough. I've looked at the wires and plugs, everything is there and in order. I do hear some squeaking of belts when it's cold, but I think I barely got it home tonight. I'm at my wits end with cars lately, and this isn't helping.
The first two things that come to mind are timing belt and ignition module. I haven't done anything else to it yet. Any thoughts on why it's running so rough? This is my daily driver and I can't even drive it right now, I don't want to be stranded. I have checked for vacuum leaks and nothing. It will stay running (though very rough), but I rev it when stopped just to make sure it does. It starts fine, too. Not hard to start. But it just runs rough. Someone please help me...
