Re: need some advise on TPI not running well when warm
If you have a data link connector, see if you can get any codes out of it. If you can read the O2 sensors see if it is leaning out when it gets hot. My guess is fuel pump also. If you have no power on accel chances are you don't have fuel pressure. If you can get a fuel pressure gauge on it to either rule it out or verify it.
