Thread: help..cold idle issues

Well i've been having this idling issues with my se-r,it seems to happen when the temperature drops below 35 degrees()..It takes about 15 min to warm up,but once it gets to operating temperature it goes away..I already replaced the coolant temperature sensor,and the oxygen sensor.I did pulled some cel's,crank position sensor,iat,oxygen sensor,and coolant temperature sensor iirc..Sorry about my grammar english is my second language..,But seriously it is..lol
And i have some vids to help with diagnostics..
Any help would be greatly apprecited..Thanks..

Ps..don't mind the lol'ing girlfriend at the end of first vid..she tried scaring me..lol

Thanks T-Bags
throttle body cleaned
ficd cleaned
iacv cleaned..
It seems like the problem is fixed,but it was kind of warm out today..We'll see.

I swapped a Ve into it,i'm still having the same problem,so it might be ficd since i swapped from the de. It has a new o2 sensor,new coolant temp sensor,i don't think the tps or the maf or dist is the problem..
Any other suggestions???

You ever fix it? I am having this same exact problem. My car pulled a 1-1. Crank Position Sensor. 1991 NX2000

Never fixed or never noticed it again since it started getting warmer soon after.

it's the cheap ass bullshit of 10% ethanol mix gas.. regular gas actually has 35% corn oil.. they just don't tell us. on the other hand turbo on corn oil is great!
