Bizarre problem starting when hot.

[maddogg20]

Hey guys,

I finally got the oil issue figured out with this damn car and now onto the next issue. When I start the car cold, it starts up fine. Throttle response can be a bit sluggish at times, but other than that she runs GREAT!!.

Now the problem. After I drive it for at least 10 minutes, if I turn it off and restart it, itll start but have a REALLY crappy low idle to the point where it shakes the car and pretty much regardless of how much you press the gas pedal it doesnt seem like it wants to rev up even if you floor it. If you push and release the gas pedal like 10 times, itll finally rev up and then hold a nice idle, but its VERY sluggish until it finally revs up. Im trying to figure out what the hecks going on here. I did some research and someone suggested that it may be the main relay, so I went ahead and fixed that by resoldering it, as well as the ICU. Im thinking maybe a fuel issue, but I already cleaned my injectors and changed the fuel filter it also has a new cap, rotor and plugs. I was also thinking maybe the TPS acts funny when it gets hot but if that was the case it shouldnt work at all once its up to temp.
Has anyone ever seen this kinda issue before?

Any helkp would be much appreciated...
Andy

my car does the exact same thing to detail except mine used to idle so low.. that is would stall. i haven't quite figured it out completely but i've done all the things u did except i put a New main relay. i raised the base idle which helped. it didn't solve the problem, it just prevented stalling..... i think its a sensor that is getting too hot.... or maybe a bad/ dirty FITV. i know my coolong fan and a/c fan aren't working properly so in my case that could help. if you figure it out lemme know. and if i get any info on it i'll let u know.
