HELP Tough Start
Looking for some advice. '98 coupe starts first time every time when cold. Drive the car 30 minutes and stop, it takes 2 or 3 trys to get it started. Any troubleshooting advice? Thanks!

Could be a few things... if it's not happening until it's warm, then it's when your car is running at operating tempture (thank you capt obvious).
Your O2 Sensor don't work until your car reaches normal operating tempature. which means a bad one won't affect the car until after the car heats up to normal operating tempature.
If your not throwing any codes, i'm gonna take a stap in the dark on this one... Spark issue. I expect some laughs at this one... but if you have the time... check all the spark plugs.. Could be a good time to replace wire/plugs if you have the time/money..

check fuel pressure. could be vapor locking.also,does it puff black smoke or smell fuellie when it does start? if so,possibly you have a evap valve hanging open[pulling fuel vapors out of the evap canister causing it to start too fat{rich}.next time,try cracking the throttle open when you start it hot,if it fires right over,i would look for it being fat
