96GTB Wagong fuel prob? 7grand spent on this problem please save me money and help!

[mackryan]

96gtb problem only occurs when coldish

new engine, air flow meter, primary turbo, coils

1,st Strong rich mixture on first start (cold)

2,nd RPM changed =/- 200' sometimes when cold and idling

3,rd When it changed into 2nd gear, the car seems to decelerate (like its looses fuel/power) then the engine sorta accelerates decelerates like its trying to figure out how much fuel to put in)

Once it warms it goes like a weapon

4th) sometimes when putting it into drive etc.. the engine RPM drops very very low and almost stalls

 

ANY help would be greatly appreciated getting sick of spending all my money on this one problem

I'd suggest replacing your coolant temp sensor. They're not overly expensive, and can really affect how the engine runs.
