I've got an '04 PT Cruiser (No turbo). The engine light came on a while back, but it ran fine for quite a while. Then, when summer came, it would quit running above 23-2400 rpm. When I slowed and got under about 60, it ran again. It seems to be fine when cold, but gets this problem after getting warmed up really well. It used to be OK again, if I turned the engine off and re-started it ...it sort of re-set....but, now, if it's warmed up well, it continues even even if re-started.

The "check engine" light is an indicator for a system that monitors many electronic functions in the system, also called the "malfunction indicator lamp" (MIL). It can come on for any of hundreds of different causes from any of the systems that the computer monitors. Some are very important and can lead to further component or engine damage and some are emissions related not as serious but still a problem and need to be repaired.
Your first step is to have the computer scanned to retrieve the trouble codes that were set when the check engine light came on. Those codes will give you specific information about what the computer saw and will get you pointed in the right direction to find your problem. With a 1996 or newer and some 95 cars and you have an AutoZone or Advanced auto parts in your area, they will read them for free. Once you have these code numbers, we can be a lot more specific about what your problem may be.
