My T100 starts like a beast when it's completely cold, but after being warmed up, it has trouble turning over. It rumbles and sometimes i have to floor it and clear it to force it to turn over and start. It's also slightly sluggish? Any ideas? Thank you!!

I have a 1996 with the same issues. I have cleaned/checked the IAC valve, replaced the hoses and gaskets, but the problem remains.. It has gotten worse as time has passed, now it starts great when cold, but won't until it sits and cools for about a half hour....have you found any solutions to this problem?' Thanks!
