My car is an 86 glh omni. I converted to t2 blow through recently. Alk parts were off a 89 Shelby z daytona. Im using mptune & GLHS 2 calibration from boostbutton. Getting it ironed out except for 1st start of the day. Pops rite off goes into normal fast idle. After about 10sec wideband goes off chart lean it about dies. Then catches up wideband goes rich. It does this crazy lean/rich dance for about 30 seconds or so then all is well. How do I go about curing this one? Also I noticed using my solous pro snap-on scanner iat sensor reads 2.50v & 102º all the time. I unplug it stays the same but engine idle is effected & then drops a code. Any help id appreciate!
