I hve been searching the internet and have seen some others have had the same problem but I have not found the fix. Problem on my 95 sprotage sohc. When its cold and I start it, it starts up with a rough idle and if you touch the gas, it dies. If you let if rough idle for a while(sometimes it dies a few times)until it gets a little warm then it runs fine. It ran good all summer, I had the same problem last winter and I thought it was the idle air control valve. I know thats not it now, because I removed it rigged my own fast idle with a manual choke cable. It has something to do with the colder weather. I have never changed the fuel filter, could this be it? What about a sticking EGR valve or something.
