I have 95 Nissan Maxima...I have trouble starting my car when the engine is cold, especially in hot or warm weather, never had a problem in winter. Please advise!!!

 

You said you have a problem starting your car when the engine is cold..you also stated that you had never had a problem in the winter.??!!..is'nt your engine more colder in the winter?..anyways..Have your battery checked out...maybe weak...or terminals on the battery may need cleaning.

 

You are correct the engine is much colder in the winter but unfortunately that is the case. Anytime the weather is warm or hot, the engine has hard time starting in the morning. Once it starts and the engine heats up to the ideal temperature, it doesn't have that problem until it seats long enough for the engine to cool down again.

Also, I checked the battery and the terminals...looks fine.

 

Clean your throttle body and check the TPS.
My 95 use to do the same thing and it was just dirty and misadjusted.
