starting issue once warms up then cools
 

I have an 88turbo with a remanufactured engine with about 5k miles. It starts right up when it is cold, but is slow to warm up. (I am starting to wonder if it may not have a thermostat?) Once warm if I cut it off then come back while still relatively warm, it starts right up. If I wait until it cools off too much it does't want to start. I just cranks and cranks unless I floor it. Any ideas on what to do or what could be causing this and how to fix it? I don't want to get stranded.

Have the injectors professionally cleaned. Check the operation of the CLT.

OK, any recomendations on places to clean injectors? I have never done anything like that so a lot of this is new to me. I know this may be dumb, but what is the CLT? Is that something a dealership will need to check? I just joined the rx7 club yesterday so I'm sure in time I will learn a lot of the abbreviations. Thanks for your help. I hate to sound like a moron, sorry.
