I have a 95 del sol si. It's been getting harder to start recently. It started to do this when it started to get cold out. I thought it was a bad battery at first. Just yesterday, the CEL came on. I haven't coded it yet. I think it needs a tune-up. I've been very busy and my friend borrows my car to go to work, so I haven't had a chance to check it out. Any ideas. The previous owner doesn't know when it was last tuned, but the distributor cap looks new and the belts are in good condition, so I don't know without digging into the engine.
