1990 L98 bogging down while under load
i have a 1990 corvette L98. when cold car is some what fine. when fully warmed up. car will bog down under load. the car will only accelerate under partial throttle. does anyone have a idea of what the problem might be.
Tps has been changed, coolant temp has been changed for the computer, iac has been changed. The only thing not changed is the map sensor. Is there any way to test the MAP SENSOR.

check for cluged converter ? the list can go on and on. is the car missing? bad coil? I would start by testing fuel pressure and volume. Then test to see if the converters are cluged.

Went into work today and changed the strainer, fuel pump and pulsator . The strainer on the fuel pump was loaded with crap and the strainer on the fuel pump was crapped up also. Once I replaced everything the car came alive. Thank you all who helped me.

yessir, I completely understand THAT one !
I spent a fortune to make mine run cool in 120 degree desert heat with the a/c on.....now I can't get the dang thing to give me more than "warm" when its 30* outside...With those ambient temps and rain the engine does not want to reach its "normal" operating temp...which is around 190. The heat exchange is so great in the big "POS Chinese knock-off" (yes, that's a dig) radiator that the fan doesn't even come on. It can't get to the min fan temp ! I drive with a parka and watch the temp gauge like it was the wheel of a slot machine, hoping to see the magic numbers that will thaw my feet .....but no. The car insist on giving me what I demanded during the hottest summer months...
Wish I had this problem in August.....
When its drizzling and freezing out, I want HOT !
