Well first time here Hope someone can help?? Can anyone Tell me where it is located on a 88? Is it control by the Ecn? can it be unpluged If you do what will happen ? Will it start hard ? My vette is going into the prest timeing mode, It will not come out of it your after it warms up good . or am i barking up the wrong tree . The enc was just replaced? throw no codes< thats why i am thinking it is not hooked to the ecn? Is burning rich now tell it come outof the pre set timeing.Will it hurt anything if i drive it this way?

Thanks Black88
