whats this

okay so i have two things going on with my 99 psd, first is the truck is like jickuping while driving almost like its gonna shut off for a split second. somtimes it will stall when i come to a stop as well, i think its a cps going? not sure though, now for the other one when i drive at any temp in first and second gear (auto trans) there is like a dead spot in power right before the turbo spools up, and it starts blowin white?maybe blueish smoke while this is happining, all i have to do is step on the throttle alittle harder and it clears right out and stops smoking, but i can hold it in this spot where it feels like its lackin power and blow smoke all the way up the road??? kinda like when its cold and doesnt want to shift and blows smoke ??? please help

Sounds like symptoms of bad timing, and perhaps a bad TPS.

I will suggest this.

Replace your CPS. it is cheap, and easy to do. Then, unhook your negative battery cables, for about 20 minutes turn your key to the run position to help drain off all capacitors, then turn the key switch off. Reconnect your negative cables and turn your key to the run position, but do not start the truck. Slowly depress the throttle pedal, to the floor, then slowly return it to the idle position. Shut the key off.

Now start the truck, and try running it. What you have done, is a soft reset of the throttle position sensor. If it clears up your problem, then you know that a TPS is in your future. You can do a hard recalibration of the TPS, but I am not going to get into that here.

Good luck
