My g/f 89 honda civic was a bi*ch to start today, never has been before. Battery was fine, but it cranked real funny, like 2 turns fast then 1 slow. It would stutter like it wanted to start, then crank slow. I pumped the gas while cranking and it fired up, ran like crap and stumbled for about 5 or 10 seconds, then smoothed out. Car has new timing belt, tune up, etc. After it ran, I shut it off, and now it starts fine. Only problem with the car right now is a crappy exhaust system. Anybody got an idea as to what could cause this? Its cold here, but its been colder recently, and it started fine. Seems to run OK when I drove it. Thanks for any help!
