These are 3 code I found on my 98 gt.

P0500 - Vehicle Speed Sensor fault.
P0171 - System Too Lean - Bank No. 1.
P0174 - System Too Lean - Bank No. 2.

new plug and wire with 2 new bosch o2 sensort, my car is smoke alot the other day and water was coming out the tail pipe, I lucky enough to fix it with head gasket repair, now it no or very little smoke when start up, after its warm up no more smoke . Could it be water destroy my o2 sensort ?

and my idle is around 800, when I put the gear to neutral to brake the car, then edometer is point at 1500 and after the car complete stop, few second later it drop down to 800 ?

thanks

Did you get coolant down in the engine when you took the PI intake off? I did and used a wet/dry vac and let it run to burn the rest off.
