87 Subaru Justy, Check Engine Light
Q: When my '87 Subaru Justy warms up, the check engine light comes on and then it seems like it is starving for gas. There was a new fuel pump put on as well as a Subaru rebuilt the carb. They could not find any data on this car....John

A: The most obvious question would be why is the check engine light coming on? As a rule when the vehicle's computer turns on the check engine light, it is not happy about something and wants to tell you about it. The fact that you have a driveability complaint in conjunction with a check engine light pretty much confirms there's a system problem. I'm not sure why the repair facility cannot find any data on your car, it's just doesn't sound right. In either case, you need a technician to ask the computer why the check engine light is on. Then you'll likely have the answer for your driveability problem is well.
