Car is stock and  starts fine when cold, and also starts fine when fully warmed, but only after siting  for a few minutes after being fully warmed up.  When fully warmed and engine siting  for around 20 to 30 min she does not start easy.   She will start after 2 minutes of cranking with the pedal to the floor and then she will run ok.  I had a spare MAF,and replaced it.  That did not change anything.  Thanks for taking the time to read this and will greatly appreciate any help.  

Carburetor or fuel injected ?

He's running a maf so you can assume SPFI or turbo MPFI. Check your temp sensor ( the one for FI not gauge ) most of the  time this is the hot start problem.

engine temp sensor, the one with 2 wores, not the single spade. especially with MPFI engines

It's  a SPFI,  I unplugged Coolant Temp Sensor (Green plug) during the hot start problem and the problem did not go away. The next day with the engine fully cooled down and the CTS still unplugged I went to start car and it started and died right away.  I am thus assuming CTS is working ok? or am I making and incorrect assumption? Thanks for taking the time to help, it is much appreciated!

I checked the ECU codes and 34  "EGR"  comes up.  Does anyone here think that this may be causing my problem? , or is it just unrelated.  Car is a 92 Loyale SPFI non turbo Auto FWD and  has only 110 000 miles, engine runs fine other than above mentioned problem.

Hi, i am still learning but i had that code when i got my 91 loyale wagon. It means the egr solenoid control valve is bad. Either electrically opened up or a bad connection. From what i have read, the computer just checks for resistance of the coil in the valve and if it does not see it it thows the code. I hear they go bad all the time. That one and the purge control valve. Same type of valve. I think the egr does not do anything untill higher rpm or load, like when you let off throttle while cruising? Other gurus will know more on that. Hope that helps somewhat

I changed CTS sensor did not help.  I put a thick ground wire from the ignition coli bracket to the neg on the battery.  Still no change.  Since the car starts fine when hot for the first 10 to 20 min, but starts hard after 30 to 40 min heat soaking, I am assuming it may be a fuel problem.  Its SPFI and I pulled the boot off the top of the throttle body after I turned off engine to see if fuel is leaking slowly and flooding it out over 30 to 40 min. I cant see it leaking, but I seem to have convinced myself it is a flooding problem.  Is their another way for me to check  if the car is getting flooded?   Appreciate the help!

Seems the problem was the TBI  slowly leaking fuel after it was warmed up and flooding engine.
