Hello, I'm new to this site, I recently bought a '94 cherokee 2.5L and wanted to try and make it run a bit smoother. When I start it cold it runs a bit rough for about 10 minutes and then it's fine when the engine has warmed up. could it be that I have to tune the valve timing(I haven't looked at the gap yet because I don't have a garage and it's been raining since I bought it )
