Well

Today is the day I start to figure out my hot idle issue

runs rough hot, figuring it leans out. let you all know how it goes later

Will

New 2.0 with ~ 1000 miles

Euro P & C

Jake CAM and lifters

Stock EFI

running rich from cold to 225 degrees F

3.6% to 3.8% CO on the Gunson and Control unit nob dialed to full lean

needless to say I have idle issues....

Where do I start boys?

Fuel pressure?

or leaky/gunked up injector(s)

hows it idle? rough?

idle is rougher as temp increases

is c.o. rich on BOTH idle and high speed?

rich cond. on high speed tend to help cool. how is the timing? advance drives up the temp.'s.

put a fuel pressure gauge on it and see if the fuel pressure is and if it holds for a good length of time

could be one leaking injector (causing high c.o. readings) and your attemping to lean out the other three to cover it. (lean/rough running overall)

you most likely can you smell the h.c.'s from the rough run (misfire)?

modified cam may make it idle funny, and hence make the mixture wrong. also I suggest you test the meter on a second known good car, just to make sure your gunson meter is reading more or less right.

before you fix any thing, make sure all four injectors are flowing the same. do this by crankin gmore to get them to flow , and place each in a test tube, so you can measure teh volume of fuel form each after say a five to ten seconds of cranking. they all should be close in volume
