hey guys i have a 90 TII and my car hesitates like it's starving for fuel until it is fully warmed up and then it is fine....my air/fuel gauge is almost in the rich when it is shuttering. is it a sensor? all emissions removed, i don't know anything about thermowax so could it be this?

 

When does it hesitate? RPM? Throttle position?

 

about half throttle it starts.....once it is warmed, it runs like a champ.

 

water thermosensor connector.... that's what solved my cold shuttering problem.

 

did you replace the sensor or just the connector...thanks

 

I replaced both.... the sensor first, then I discovered it was the connector that was bad. lol.

 

cool...thanks again i will do it, heck it needs it anyway

 

BTW, you should be throwing a CEL on start up if its out though... are you throwing any codes?

 

my check engine light never came on but i know the light works bc when my o2 sensor came loose it came on.

 

then maybe the tps or afm is outta whack a little? run some tests with a multimeter, refer to the FSM for specs, available in the FAQ's. those would be my three culprits.
